Hello All
Do we put all our eggs in the Big Bang Theory or do we investigate another theory such as the reycling process?

Re: Origins of the Universe
I moved this post to the Cosmology forum away from the general discussion forum.
I feel I should point out a couple things here. First let me say that your question is a valid question which merits responsive and open-minded discussion, however, there are currently discussions pertaining to the BB Theory and other possibilities already in progress here in the Cosmology forum.
Secondly, and most important, the title of this has already been used more than once in the past with less than favorable results. There are members from all over the world of all ages and walks of life. Everyone has their own beliefs and convictions. Most are attracted to these forums for one purpose. That's because this web site is dedicated to the amateur astronomer, and the sciences of astronomy. Without going into detail I will refer you to the forum policies concerning religious and political discussions within these forums. If you have not already read that policy, which is posted in the Off Topic area, discussion that are Contain and or are Religiously and or Politically charged are prohibited. Unfortunately, the title in and of itself has in the past invited less than civil contention between some of the members here. Discussions pertaining to the origins of the universe can get fervid and out of hand very quick. If this thread or any other shows any signs of turning that direction, the appropriate action(s) in accordance with current policies will have to be taken.
Have A Nice ___________

Re: Origins of the Universe
If thermodynamics is true then all the atoms that exist today have always existed in various forms throughout the infinite past and will throughout the infinite future. Atoms do not care how old we think the universe is or how it got there. If the past is truly infinite then all the atoms in the universe would have had time to Shake hands via gravity and would "know" about each other. If time began with the BB. Then what event in the future could cause time to cease to exist? Perhaps atoms produce gravity by choice so they can get together to form different things or perhaps they become the victims of gravity and simple clump beyond there individual control. No one has been proven correct as identifying the actual "cause" of gravity. It can only be passively measured. Same as the BB. Given that we have no idea how the Big Bang could have happened, what we believe we are seeing "out there" leads us to believe that it "must" have happened. The funny thing about universal observations is that they put Earth at the center of the universe. Experts deny that we could be at the center but refuse to believe that anyone at what we reckon the edge of the universe would be able to see anything beyond that point. Silly isn't it? Perhaps the universe does recycle. A message from the stars on how to conduct business here? BQ

This is not an accurate representation of BBT: In the earliest epochs there were no atoms at all. Once the universe had cooled sufficiently for atoms to form, only the lightest three or four elements existed in atomic form until stars formed. Once star formed, limited stellar nucleosynthesis shifted the proportions of the lightest elements via nuclear fusion (e.g., as time went on, hydrogen was converted to helium, and so on, so the relative proportions began to shift). And once stars got old enough to progress beyond helium fusion and/or exploded in supernovae, heavier elements formed and were distributed throughout their local regions of the universe (which went along with the general cosmological expansion).
If time began with the BB. Then what event in the future could cause time to cease to exist?
Depends on whether you define time as an entity independent of physical entropy. So, for example, if the ultimate fate of the universe is continued expansion to ultimate entropical heat death, then at some point change would cease and there would be no observance of time.
Perhaps atoms produce gravity by choice so they can get together to form different things or perhaps they become the victims of gravity and simple clump beyond there individual control. No one has been proven correct as identifying the actual "cause" of gravity. It can only be passively measured. Same as the BB.
If by "passively measured" you mean simply observed, then okay. But many of the tenets of BBT are based on working knowledge of experimental nuclear physics (independently verified many times over).

Re: Origins of the Universe
It was not intended to accurately represent the BBT. It was an imaginative look at the possibility that atoms might have always been here without the BB leading to their eventual birthdays. BQ

Hello All

No, we do not put all our eggs in one basket. However, physicists and cosmologists have been working for decades on unifying theories, so the trend is toward standard models. Note the plural. The BBT is such a model and is well-supported by observational evidence.
There are several other hypothetical models, some of which include all or parts of the BBT but go beyond it (backward in time) and -- while entirely speculative and thus far untestable -- are active areas of research by many scientists. Some of those scientists likewise support the standard model we call the BBT.
Doubtless, there are some who have their heads in the sand. But that does not mean there are not credible creative and imaginative minds at work in cosmology as well. No worries.

Re: Origins of the Universe
In my short readings of M theory I think I have come to believe that what we know as our universe, may never have not exsisted, or perhaps never had an explicit begining or start. That perhaps energy and matter always exsisted but just in different forms. I have read that our universe may have gone through phase changes, similar to how H20 Can be liquid, solid or gas in form as we percieve it.
So perhaps the values of such things like the fundamental four forces or the postulated higgs boson are variable over infinity.
But then comes into play the question of time, what is time, has it always been as we percieve it now? Perhaps what we know as time is only what is described in the man written laws of thermodynamics and in particular entropy. Maybe there is no time as we know it but only an interval of infinity where matter and energy always exsisted but because of yet some unknown quantity the values of forces are variable.
And what of Dark energy and Dark matter? M theory proves to be more interesting every second, some places I have read think dark energy is implicit outward pressure caused by quantum vaccum flucturations, making me wonder if even now as I type this the values of all things known are constant over any interval. How can we possibly explain the vast majority of energy/matter in the universe being reserved for these unknown ghostly postulations.. We are missing something, something big. I can only hope M theory has it.
And on the Big ban theory, I truely dislike the name, as a bang implies some short of chemical interaction causing what we know to be an explosion of shorts, but it was really an extremely rapid expansion of space itself..
Who knows, it just seems to me that everything is a sea of interconnected and related values..

Re: Origins of the Universe
The BBT is currently the standard model because:
-
It fits the data better than any other theory we have.
-
It has survived all its significant tests.
-
It has the support of the vast majority of cosmologists.
Is it perfect? No.
Are there/will there be challenges? Yes.
In your metaphor, is it broken? Not even cracked.
We're each entitled to our opinions here. Are we cosmologists? No. Can some of us reproduce the data used in support of the BBT? A very few of us here can, to at least a limited extent. This doesn't make us particularly well-qualified to challenge, or to support, the theory in general.
Still, it's interesting and to at least some of our members it's educational to discuss it and various challenges to it. And it can be a great deal of fun.
The major reason I respond to posts about it here is to clarify points that are made either erroneously or perhaps a bit carelessly about the tenets of the BBT and their interpretations and supporting evidence. The thing that most often causes me heartburn with these discussions is statements that would lead those unfamiliar with its underpinnings to conclude that the BBT is in disfavor among cosmologists.
It certainly has critics among that community, and some of them are vocal. But in the aggregate they represent a very small percentage of working cosmologists and astrophysicists and very, very few of them are in favor of abandoning it in toto.
One point I'd like to make in support of the BBT here is that the theory of the origin of the universe is a very, very big deal. It is, essentially, the Big Question: Where did we come from and where are we going? So of course it is going to generate discussion. It is very unlikely to be a simple answer, too, so there will be ample room for challenge and debate.
As you can tell from some of the references supplied in the post above, though some of the challenges seem to be coming "from left field", perhaps equally as many arise because of new observational technology and methods that create as many problems as they resolve!
That is the nature of modern scientific inquiry ...
Fear not. If this is your goal:
At the end of the day, I want to know that what ever theory we are putting our eggs in is close to the one that is supported by science. I do not like my eggs broken.
... then the BBT is the one that is supported by most researchers ...

That perhaps energy and matter always exsisted but just in different forms. I have read that our universe may have gone through phase changes, similar to how H20 Can be liquid, solid or gas in form as we percieve it.
Stars and galaxies do go through their phases and stages of evolution. Matter to energy to matter cycling.

I think so.
But then comes into play the question of time, what is time, has it always been as we percieve it now? Perhaps what we know as time is only what is described in the man written laws of thermodynamics and in particular entropy. Maybe there is no time as we know it but only an interval of infinity where matter and energy always exsisted but because of yet some unknown quantity the values of forces are variable.
Time cannot be changed only the relative time in communication that measures duration. Its not an ITEM that lends itselve to change to past or future.
And what of Dark energy and Dark matter? M theory proves to be more interesting every second, some places I have read think dark energy is implicit outward pressure caused by quantum vaccum flucturations, making me wonder if even now as I type this the values of all things known are constant over any interval. How can we possibly explain the vast majority of energy/matter in the universe being reserved for these unknown ghostly postulations.. We are missing something, something big. I can only hope M theory has it.
Dark energy and dark matter were brought in to explain galaxy movements and as an ad hoc ideas to make the big bang theory fit the model.
And on the Big ban theory, I truely dislike the name, as a bang implies some short of chemical interaction causing what we know to be an explosion of shorts, but it was really an extremely rapid expansion of space itself..
Many people people think of the big bang as one big bang and the expansion as actual distance expansion.The theory states that it occured everywhere at the same time from a singularity point and the expansion is not actual, but! time-space expansion.
Who knows, it just seems to me that everything is a sea of interconnected and related values..
Yes, I may agree with you on that.
Regardless, keep reading.

What data? and Why did it survive the tests? and Why has it majority of support? These are questions that need to be aswered by the people who funded the theory. People were told, the data fit the theory and that it has been tested time and time again. This created a movement and people did not question the data supplied.

Changes occur through science, and at this moment, people are questioning the data and the observations.

Its up to you to further research the current information.

Do you really understand the Big Bang Theory, or just support it for the love of it.

Rather than me supplying hundreds of links to support alternative theories, maybe you should read up on the topic.

Re: Origins of the Universe
Harry:
As you can tell by reading my posts on the subject of the BBT, I do trot out the data in response to specific points being made. I don't intend to publish a treatise on the subject here, or anywhere else.
I have about 6 linear feet (a shelf and a half) of books about BBT and cosmology. So, I have read quite a bit about the subject. The first book I read about it was Gamow's and if memory serves that was in 1953. I have been studying it off and on ever since. I am familiar with it, despite the fact that my interests in astronomy are not primarily in cosmology.
I do also regularly read articles published in scientific journals, particularly when they challenge parts of the standard model. One of the nice things about astronomy today compared to when I started out is that the Internet makes this much easier to do.
As to precisely how many or what percentage of cosmologists support the standard model and BBT, it is certainly the majority today. What happened in the past year to change it? While it is true there is no "vote" taken formally to establish the BB as working theory, it also is true that if the majority of cosmologists opposed it then it would not be taken as established theory -- it would be a working hypothesis. It is well past that stage and today's challenges do not seem to threaten it in toto.
I have said here many times, including the post you referenced, the BBT is not perfect. My reply in that post was to correct the interpretation that it is seriously broken. It is not. Sure, there are challenges.
But here's a bigger point: there is no serious challenger overall. That is, there is no proposed theory that already has passed its own challenges to reach the status of Theory. There are some interesting hypotheses. Many people like string theory and M or brane theory. Neither is theory: they're hypotheses. They are not (perhaps not yet) testable. A theory must be.
The BBT is a working theory. Not by fiat, but by having survived various challenges and adopting data acquired by new technologies and methods and evolving to its current form. It has been questioned -- and seriously -- many times. You allude to current questions and challenges, as well.
That's how science works ... not by the likes of you and me sitting around discussing it.
The good that comes of folks like us discussing it is that those who haven't read as much about it might learn something from the discourse.

Re: Origins of the Universe
The BBT does not need or require another theory thats more 'correct" for it to be overall, "wrong".
The only reason BBT survives is because no one has any better idea's. This again, does not make make it a correct theory.
Let be carefully not to assume that because a theory has no rivals ready to overtake it, that its correct in any shape or form.
DATA and OBSERVATION are the only litmus tests.
So, maybe someone should post ONE Challenge to BBT and another post the Solution.
Then at the end we can determine for ourselves if the BBT takes too many liberties with imaginary data for it to be correct.
Test,

But let's not delude ourselves into thinking we are going to answer this question on these forums. For my money, the BBT is the best we've got for the time being.

Re: Origins of the Universe
Test4echo:

That is correct. But the BBT is part of the Standard Model because it fits the data better than all its rivals combined. There are no significant, testable rivals. You could say the BBT is wrong except that it fits the preponderance of the data, not just one or two bits of it. You could say that a rival hypothesis is correct if it fits one or two bits of the data, but that doesn't make it a theory of the same order as the BBT.
The only reason BBT survives is because no one has any better idea's. This again, does not make make it a correct theory.
That is partly correct. The first sentence is wrong: the BBT survives as a theory because its multiple hypotheses have been tested repeatedly against observational data and found to be correct. The second sentence is correct: if a better idea comes along (and fits the data better, or answers correctly more of the challenges to BBT) then it could displace the BBT.
Let be carefully not to assume that because a theory has no rivals ready to overtake it, that its correct in any shape or form.
Yes. I do not make that assumption. However, so much of the BBT survives testing that it is assumed to be correct. That is how hypotheses become Theory. A theory is accepted by working scientists as the standard for moving forward. So, once again, find a bit or two here or there to complain about and fine: you work it out and see what needs amending or adding to the model. It's not until you find a lot of those, or one or two MAJOR tenets that are incorrect that you consider scrapping the theory itself. That is simply not the case with the BBT today.
DATA and OBSERVATION are the only litmus tests.
So, maybe someone should post ONE Challenge to BBT and another post the Solution.
Then at the end we can determine for ourselves if the BBT takes too many liberties with imaginary data for it to be correct.
In principle, that's correct. it happens quite often here. In fact it happened just a few days ago with the tired light idea (which has passed zero of its challenges).
However, WE (here in these Forum threads) are not the ones to do that in any formal way. Do we have the means to do it? We can offer thought experiments. We can point out what researchers are doing. A few of us may be able to participate in actual research at some small level. But let's not make the mistake of assuming that our imaginations and resources are on the same level as those of current researchers.
Are our conclusions as valid as those of working cosmologists? As opinions, yes. As science, no. While this does not mean that members here are incapable of doing science, I am saying that we can't expect that our opinions or musings here are relevant to the scientific community.
Astronomy Magazine (among others) does a good job of highlighting recent and relevant research. Focus topics and special issues get even deeper into discussions of cosmology.
But I'm not aware of a working cosmologist or astrophysicist signed in as a member of the Discussion Forum here ...
As I said before, what we can do here (and in the time I've been a member I have seen many shining examples of this from our members) is offer coherent and informative discussions about the issues.

Re: Origins of the Universe
Hello All
The mistake in history made time and time again is that the minute "MAN" thinks he or she knows, thats the minute research and learning stops.
So!!!!!!!! we have the standard model. Do we stop researching and learning and going where no man has gone before, do we stretch our wings and fly higher in fear of falling.
Look at history, time and time again it happens.
So! take the time and question.

A New Non-Doppler Redshift http://www.newtonphysics.on.ca/hubble/index.html
| QUOTE |
It is known that many astronomical observations cannot be explained by means of the ordinary Doppler shift interpretation. The mere examination of a recent catalog of objects having very large redshifts shows that among 109 quasi-stellar objects for which both absorption and emission lines could be measured, the value of the absorption redshift of a given object is always different from the one measured in emission for the same object. It is clear that such results cannot be explained as being due solely to a Doppler redshift. A new mechanism must be looked for, in order to explain those inconsistent redshifts and many other observations related to the “redshift controversy”. |
International Workshop on Redshift Mechanisms in Astrophysics and Cosmology (Clonakilty-Cork, Ireland, May 15-18, 2006) http://redshift.vif.com/NewsWire/BrassTacksRelease1.pdf
| QUOTE |
An extraordinary event took place recently in Ireland. A group of independent and professional researchers met to discuss an old heterodox topic with important consequences in astrophysics and, especially, in cosmology: possible causes of the redshifts in the spectra of astrophysical objects other than a Doppler or expanding universe mechanism. Many decades of work have been devoted to this kind of research, most of it forgotten by the greater part of the astrophysical community nowadays. But the question is still open, the debate is still alive, as was shown by the participants in the present Workshop. There is no smoke without fire, and the existence of many facts and theories on alternative origins of redshifts may point to some new pathways in physics that deserve further attention. This was precisely the aim of this meeting. |
Further Evidence that the Redshifts of AGN Galaxies May Contain Intrinsic Components http://www.citebase.org/fulltext?for...rg%3A0704.1631
| QUOTE |
Because the belief that the redshift of quasars is cosmological has become so entrenched, and the consequences now of it being wrong are so enormous, astronomers are very reluctant to consider other possibilities. However, there is increasing evidence that some galaxies may form around compact, seed objects ejected with a large intrinsic redshift component from the nuclei of mature active galaxies. In this model, as the intrinsic component decreases the compact objects evolve into mature active galaxies in a time frame of a few times 108 yrs (Arp 1997, 1998, 1999; Bell 2002a,b,c,d, 2004, 2006; Bell and McDiarmid 2006, 2007; Burbidge 1999; Galianni et al. 2005; Lop´ez-Corredoira and Guti´errez 2006). In the DIR model radio galaxies represent the end of the AGN evolutionary sequence, where most of the intrinsic redshift component has disappeared and their luminosity has peaked. Only then can these objects be detected to large cosmological distances and can it be seen that they are good standard candles. There is every reason to assume that at each stage of their evolution (at each zi value) they will also be good standard candles. |
On the Quantization of the Red-Shifted Light from Distant Galaxies http://www.ldolphin.org/tifftshift.html
| QUOTE |
As the turn of the next century approaches, we again find an established science in trouble trying to explain the behavior of the natural world. This time the problem is in cosmology, the study of the structure and "evolution" of the universe as revealed by its largest physical systems, galaxies and clusters of galaxies. A growing body of observations suggests that one of the most fundamental assumptions of cosmology is wrong.
Most galaxies' spectral lines are shifted toward the red, or longer wavelength, end of the spectrum.
Edwin Hubble showed in 1929 that the more distant the galaxy, the larger this "redshift." Astronomers traditionally have interpreted the redshift as a Doppler shift induced as the galaxies recede from us within an expanding universe. For that reason, the redshift is usually expressed as a velocity in kilometers per second.
One of the first indications that there might be a problem with this picture came in the early 1970's. William G. Tifft, University of Arizona noticed a curious and unexpected relationship between a galaxy's morphological classification (Hubble type), brightness, and red shift. The galaxies in the Coma Cluster, for example, seemed to arrange themselves along sloping bands in a redshift v.s. brightness diagram. Moreover, the spirals tended to have higher redshifts than elliptical galaxies. Clusters other than Coma exhibited the same strange relationships.
By far the most intriguing result of these initial studies was the suggestion that galaxy redshifts take on preferred or "quantized" values. First revealed in the Coma Cluster redshift vs. brightness diagram, it appeared as if redshifts were in some way analogous to the energy levels within atoms.
These discoveries led to the suspicion that a galaxy's redshift may not be related to its Hubble velocity alone. If the redshift is entirely or partially non-Doppler (that is, not due to cosmic expansion), then it could be an intrinsic property of a galaxy, as basic a characteristic as its mass or luminosity. If so, might it truly be quantized? |
| QUOTE |
| The Hubble law for the large scale redshift of galaxies is usually taken as evidence (if not proof) for the picture of an expanding universe in general and the Big Bang theory in particular. However, recessional velocities have by no means been actually measured and the assumption of the Doppler effect being responsible for the shift is only reached due to the absence of other known physical explanations. In fact, the Hubble law appears to be based on rather limited data sets, and in particular has not been examined for its strict validity throughout the whole of the electromagnetic spectrum (in fact, it is known that the redshift factor for certain spectral lines from the same object differs by up to 10% even within the visible part of the spectrum itself). |

There are more recent (2007) data on this, with attendant explanations that do not require scrapping the existing cosmological redshift model. Still, I agree more data is needed. I'll try to find a link to the 2007 explanation and return with a link this weekend.

Many decades of work have been devoted to this kind of research, most of it forgotten by the greater part of the astrophysical community nowadays. But the question is still open, the debate is still alive, as was shown by the participants in the present Workshop. There is no smoke without fire, and the existence of many facts and theories on alternative origins of redshifts may point to some new pathways in physics that deserve further attention. This was precisely the aim of this meeting. |
Further Evidence that the Redshifts of AGN Galaxies May Contain Intrinsic Components http://www.citebase.org/fulltext?for...rg%3A0704.1631

Because the belief that the redshift of quasars is cosmological has become so entrenched, and the consequences now of it being wrong are so enormous, astronomers are very reluctant to consider other possibilities. However, there is increasing evidence that some galaxies may form around compact, seed objects ejected with a large intrinsic redshift component from the nuclei of mature active galaxies. In this model, as the intrinsic component decreases the compact objects evolve into mature active galaxies in a time frame of a few times 108 yrs (Arp 1997, 1998, 1999; Bell 2002a,b,c,d, 2004, 2006; Bell and McDiarmid 2006, 2007; Burbidge 1999; Galianni et al. 2005; Lop´ez-Corredoira and Guti´errez 2006). In the DIR model radio galaxies represent the end of the AGN evolutionary sequence, where most of the intrinsic redshift component has disappeared and their luminosity has peaked. Only then can these objects be detected to large cosmological distances and can it be seen that they are good standard candles. There is every reason to assume that at each stage of their evolution (at each zi value) they will also be good standard candles. |
At the Texas Star Party in 2004, Dr. Arp was a featured speaker. He was quite well received. The amateur (and semi-pro) community is much more open to discussions with what are sometimes called "fringe theorists". I really enjoyed his talk. I had breakfast with him the next morning, as part of an interview for Astronomy Magazine's TSP blog (which Jay Ballauer and I were doing for this website). He was aware of pending publication of newer data and explanations which might invalidate his "ejection" premise. The point he made in his presentation was that his explanation (and those offered by his grad students doing the computer modeling) precisely fit the data, and within the measurement uncertainties fit it as well as the accepted cosmological redshift models. He further argued that what he and his students and supporters were doing was acceptable discovery science, and I agreed with him about that.
At breakfast the next morning, I asked him what he thought was the gravest risk to such theories as his, and he replied that (I'm paraphrasing here): "Discovery science itself could be deprecated, without good reason. So there might be new data that show our explanations are invalid. That's okay. What's not okay is for folks to get the idea that discovery science is passe or even wrong to go do. We need people out there on the bleeding edge coming up with new ideas to fit the data, and generating that data. We need to feel it's okay to occasionally be wrong in the pursuit of better data."
He was especially concerned that discovery science be thought good enough to warrant telescope time. He was concerned that students wanting to do off-the-beaten-path research might not get the telescope time to develop the data that supported or countered their own ideas.
I certainly would agree with that.
He went further, saying that if we get in that sort of situation, it will discourage new students from pursuing alternative approaches, which might be a bad thing.
I can agree with that, as well, though I'm not aware of the extent to which it may be occurring.
On the Quantization of the Red-Shifted Light from Distant Galaxies http://www.ldolphin.org/tifftshift.html

As the turn of the next century approaches, we again find an established science in trouble trying to explain the behavior of the natural world. This time the problem is in cosmology, the study of the structure and "evolution" of the universe as revealed by its largest physical systems, galaxies and clusters of galaxies. A growing body of observations suggests that one of the most fundamental assumptions of cosmology is wrong.
Most galaxies' spectral lines are shifted toward the red, or longer wavelength, end of the spectrum.
Edwin Hubble showed in 1929 that the more distant the galaxy, the larger this "redshift." Astronomers traditionally have interpreted the redshift as a Doppler shift induced as the galaxies recede from us within an expanding universe. For that reason, the redshift is usually expressed as a velocity in kilometers per second.
One of the first indications that there might be a problem with this picture came in the early 1970's. William G. Tifft, University of Arizona noticed a curious and unexpected relationship between a galaxy's morphological classification (Hubble type), brightness, and red shift. The galaxies in the Coma Cluster, for example, seemed to arrange themselves along sloping bands in a redshift v.s. brightness diagram. Moreover, the spirals tended to have higher redshifts than elliptical galaxies. Clusters other than Coma exhibited the same strange relationships.
By far the most intriguing result of these initial studies was the suggestion that galaxy redshifts take on preferred or "quantized" values. First revealed in the Coma Cluster redshift vs. brightness diagram, it appeared as if redshifts were in some way analogous to the energy levels within atoms.
These discoveries led to the suspicion that a galaxy's redshift may not be related to its Hubble velocity alone. If the redshift is entirely or partially non-Doppler (that is, not due to cosmic expansion), then it could be an intrinsic property of a galaxy, as basic a characteristic as its mass or luminosity. If so, might it truly be quantized?
I only remember one of the counter-arguments to the above, and it was accepted (that doesn't mean it invalidates the whole premise): that galaxy morphology has very little to do with galactic evolution except in the very broadest sense. That is, the original Hubble "tuning-fork diagram" has little basis in evolutionary fact, and is only an observational bias (an unintentional one). Last year I met a U. of Wisconsin astronomy major who is specializing in galactic evolution. I also know one of the astronomers at the Keck observatories, whom I corresponded with last year about spiral arms as "density waves." Although we didn't discuss the above topic specifically, we have discussed cosmological redshift and their view is that the observational support is very strong except at extreme look-back times. That's probably understandable ...
I am not aware of data that shows galactic redshift to be significantlyl quantized. It would be interesting to see, so I'll look for it.

The Hubble law for the large scale redshift of galaxies is usually taken as evidence (if not proof) for the picture of an expanding universe in general and the Big Bang theory in particular. However, recessional velocities have by no means been actually measured and the assumption of the Doppler effect being responsible for the shift is only reached due to the absence of other known physical explanations. In fact, the Hubble law appears to be based on rather limited data sets, and in particular has not been examined for its strict validity throughout the whole of the electromagnetic spectrum (in fact, it is known that the redshift factor for certain spectral lines from the same object differs by up to 10% even within the visible part of the spectrum itself).
What? There are many measurements of recessional velocities! "Lmited data sets" is simply not correct. Hubble's own measurements were limited, but the data has been greatly expanded since new technology allows determination of thousands of galactic spectra -- at multiple wavelengths -- in a given night. The above quote seems totally off-base to me ...
I just finished reading Joseph Silk's On the Shores of the Unknown, a 2005 summary of what we know, and how we learned it, about the origin of the universe. At one point he mentions that the then-accepted precision of the Hubble constant was plus/minus ~7.5 percent. He follows this with an entire section devoted to sources of uncertainty in various methods of measuring recessional velocities and redshifts. It is interesting reading.
As to the claim, above, that the Hubble Law has not been examined for its strict validity throughout the whole of the electromagnetic spectrum well, of course it hasn't. That is a LOT of territory. However, let me add it has been measured at many different optical frequencies, it has been been measured at radio wavelengths for decades, and it is now being measured at X-ray and gamma-ray wavelengths. I submit that current research is not exactly flying blind here, nor has it for the past several decades.

Non-Doppler Redshift Mechanisms with Possible Cosmological http://flux.aps.org/meetings/YR03/AP...0.html#SR9.015
====================================================
If the Big Bang cannot stand up to the winds of science, stop trying to protect it from falling, by adding ad hoc props.
As a scientific theory, the BBT is no different from other theories except as to its scope (it is THE big question, after all). It is common practice to alter a theory based on new data, and to incorporate new interpretations as they are required. One of the things we should keep in mind about the BBT as we research alternatives is that better than any other cosmological model we have today, it rests on multiple pillars of supporting data.
I totally agree with the idea that as questions arise based on new data, or new interpretations of old data, they should not be quashed but actively addressed. Research should not only be allowed along these lines, but should be actively encouraged. I'm not aware of any aggressive movement by BBT supporters to quash the competition. But I do understand there is risk as outlined by Dr. Arp.
I'm enjoying this discussion. Others should add to it besides the three or four of us so far!
I will be out with a group of college astronomy students under a nice, dark sky with some serious glass this weekend, and won't be able to check in again after this evening for a while ...

Re: Origins of the Universe
Hello Chip
Your response was extremely quick and by your writing, you know a bit about cosmology.
Rather than trying to blow down any theory.
Lets look at the basics, the workings of the parts of the universe and than fit them back to what ever theory.
So! we have a clean slate, dish, plate and so on.
We can look at
Star formation and varies stages.
Compact degenerate matter
Galaxy Evolution
OOPs
Got to go and pick up the kids

G'day from the land of ozzzzz
We have been told that nothing can escape a black hole, assuming that a singularity exists. There is no evidence to indicate that a singularity can be formed.
So! for now we can study the compacted matter that we assume axits in Neutron Star, varies other exotic stars and the so called Nucleons that are called black holes.

| Sheared Flow As A Stabilizing Mechanism In Astrophysical Jets |

| Abstract: It has been hypothesized that the sustained narrowness observed in the asymptotic cylindrical region of bipolar outflows from Young Stellar Objects (YSO) indicates that these jets are magnetically collimated. The j cross B force observed in z-pinch plasmas is a possible explanation for these observations. However, z-pinch plasmas are subject to current driven instabilities (CDI). The interest in using z-pinches for controlled nuclear fusion has lead to an extensive theory of the stability of magnetically confined plasmas. Analytical, numerical, and experimental evidence from this field suggest that sheared flow in magnetized plasmas can reduce the growth rates of the sausage and kink instabilities. Here we propose the hypothesis that sheared helical flow can exert a similar stabilizing influence on CDI in YSO jets. |

| Abstract: We have performed several simulations of black hole systems (non-rotating, black hole spin parameter a=0.0 and rapidly rotating, a=0.95) with a geometrically thin Keplerian disk using the newly developed RAISHIN code. The simulation results show the formation of jets driven by the Lorentz force and the gas pressure gradient. The jets have mildly relativistic speed (\sim 0.4c). The matter is continuously supplied from the accretion disk and the jet propagates outward until each applicable terminal simulation time (non-rotating: t/\tau_S = 275 and rotating: t/tau_S = 200, \tau_S \equiv r_S/c). It appears that a rotating black hole creates an additional, faster, and more collimated matter-dominated inner outflow (\sim 0.5c) formed and accelerated by the twisted magnetic field resulting from frame-dragging in the black hole ergosphere. This is the first known simulation confirming the formation of an inner magnetically-driven, matter-dominated jet by the frame-dragging effect from a black hole co-rotating with a thin Keplerian disk threaded by a vertical magnetic field. This result indicates that jet kinematic structure depends on black hole rotation and on the initial magnetic field configuration and strength. |

| We present the first results of high energy density laboratory astrophysics experiments which explore the evolution of collimated outflows and jets driven by a toroidal magnetic field. The experiments are scalable to astrophysical flows in that critical dimensionless numbers such as the Mach number, the plasma beta and the magnetic Reynolds number are all in the astrophysically appropriate ranges. Our experiments use the MAGPIE pulsed power machine and allow us to explore the role of magnetic pressure in creating and collimating the outflow as well as showing the creation of a central jet within the broader outflow cavity. We show that currents flow along this jet and we observe its collimation to be enhanced by the additional hoop stresses associated with the generated toroidal field. Although at later times the jet column is observed to go unstable, the jet retains its collimation. We also present simulations of the magnetic jet evolution using our two-dimensional resistive magneto-hydrodynamic (MHD) laboratory code. We conclude with a discussion of the astrophysical relevance of the experiments and of the stability properties of the jet. |

| Abstract: The jets observed to emanate from many compact accreting objects may arise from the twisting of a magnetic field threading a differentially rotating accretion disk which acts to magnetically extract angular momentum and energy from the disk. Two main regimes have been discussed, hydromagnetic jets, which have a significant mass flux and have energy and angular momentum carried by both matter and electromagnetic field and, Poynting jets, where the mass flux is small and energy and angular momentum are carried predominantly by the electromagnetic field. Here, we describe recent theoretical work on the formation of relativistic Poynting jets from magnetized accretion disks. Further, we describe new relativistic, fully-electromagnetic, particle-in-cell simulations of the formation of jets from accretion disks. Analog Z-pinch experiments may help to understand the origin of astrophysical jets. |

| Abstract: We present first results of astrophysically relevant experiments where highly supersonic plasma jets are generated via conically convergent flows. The convergent flows are created by electrodynamic acceleration of plasma in a conical array of fine metallic wires (a modification of the wire array Z-pinch). Stagnation of plasma flow on the axis of symmetry forms a standing conical shock effectively collimating the flow in the axial direction. This scenario is essentially similar to that discussed by Canto\' ~and collaborators as a purely hydrodynamic mechanism for jet formation in astrophysical systems. Experiments using different materials (Al, Fe and W) show that a highly supersonic ($M\sim 20$), well-collimated jet is generated when the radiative cooling rate of the plasma is significant. We discuss scaling issues for the experiments and their potential use for numerical code verification. The experiments also may allow direct exploration of astrophysically relevant issues such as collimation, stability and jet-cloud interactions. |

| Instability of toroidal magnetic field in jets and plerions |

| Authors: Mitchell C. Begelman (JILA, Boulder, USA) |

| Quote: |
| Abstract: Jets and pulsar-fed supernova remnants (plerions) tend to develop highly organized toroidal magnetic field. Such a field structure could explain the polarization properties of some jets, and contribute to their lateral confinement. A toroidal field geometry is also central to models for the Crab Nebula - the archetypal plerion - and leads to the deduction that the Crab pulsar's wind must have a weak magnetic field. Yet this `Z-pinch' field configuration is well known to be locally unstable, even when the magnetic field is weak and/or boundary conditions slow or suppress global modes. Thus, the magnetic field structures imputed to the interiors of jets and plerions are unlikely to persist. |
| To demonstrate this, I present a local analysis of Z-pinch instabilities for relativistic fluids in the ideal MHD limit. Kink instabilities dominate, destroying the concentric field structure and probably driving the system toward a more chaotic state in which the mean field strength is independent of radius (and in which resistive dissipation of the field may be enhanced). I estimate the timescales over which the field structure is likely to be rearranged and relate these to distances along relativistic jets and radii from the central pulsar in a plerion. |
| I conclude that a concentric toroidal field is unlikely to exist well outside the Crab pulsar's wind termination shock. There is thus no dynamical reason to conclude that the magnetic energy flux carried by the pulsar wind is much weaker than the kinetic energy flux. Abandoning this inference would resolve a long-standing puzzle in pulsar wind theory. |

| There is a trend to find what is actually driving the jets and ejecting matter from compact cores such as the so called black holes. |
| |
| Black holes with singularity I do not think they exist. But! black holes that have a compacted core that acts like a Nucleon and having a mass about 3 or greater than our sun may create electromagnetic fields that may prevent EMR from escaping. |
