Re: Mystery of rapidly expanding universe solved.
No, matter is not expanding. It's only on the very macro level.

Deep field images show a clustering effect. Galaxies tend to merge in their evolution. Yes there is monster jets that are found in clusters of galaxies that eject matter out in huge amounts creating and triggering new star formation and in turn evolving dwarf galaxies that merge to form larger galaxies.
The expansion of the universe is not actual, But! spacetime expansion.

Re: Mystery of rapidly expanding universe solved.
I think you did a good job with your explanation Harry. I personally don’t understand such a question very well. Why would anyone ever conclude that expansion is going on at the subatomic level?
If that were going on, then the forces involved in our everyday life, would also have to adjust or things would quickly deteriorate. Atoms are smaller than the wavelengths of light. If only atoms enlarged then we would soon be able to see them. But there would be so many other repercussions that this would just be an impossibility. So then when you are asking about everything enlarging, then I assume they are also talking about the forces of nature compensating for this growth as well. In short, that everything is growing!
If this were the case, how would you measure such growth? Lets say you have a Chess piece that’s 4.5 inches tall. You know this because you measured it the other night with a ruler. Now say that everything, and I do mean everything, doubled in size over night.
How would you measure it? Would the Chess piece now stand 9 inches tall? Would it no longer fit on the chess board? If everything doubled in size then that means that you doubled in size, your bed doubled in size, the ruler doubled in size, the Chess board doubled in size, the house doubled in size, the earth, the sun, the solar system, the galaxy, and the universe doubled in size. How would you measure that?
The answer is you couldn’t. Size comparison would be invariant under these circumstances. In other words you can’t measure it by any comparison, so to say that anything is growing or shrinking under these conditions is really just hearsay. It’s mute. It’s not worth discussing because you have no proof, or even a reason to imply such a condition.
Growth is only measurable when you have something to compare it with. Trees grow, and babies grow because we have something to compare them to, but Chess pieces don’t grow. Atoms don’t grow.
Sound waves don’t grow, so a sound with a certain pitch doesn’t change, that is, if the conditions surrounding the source are unchanged. If the source is moving however the pitch will change. We can measure this change.
The wavelengths of light don’t grow. The spectrum of light wavelengths are of a steady nature. But if the source is moving, then the spectrum of light is shifted. We can compare this to a steady spectrum of light and measure this change.
Andromeda Galaxy is headed for our galaxy. We know this because the light coming towards us from this galaxy is shifted into the blue end of the spectrum. Using only this measurement, we could almost come to the conclusion that our universe is shrinking, and will eventually collapse in on itself. But we have taken a lot of other measurements with galaxies that are much further away, and found out that while local galaxies may eventually merge with each other, the universe as a whole is expanding. This is all based on comparisons of with what we know is set and firmly fixed. Observations of galaxy mergers, and the history of our universe through the lenses, via telescopes also confirms this story.
Is this better Harry?

Hello Dusty, I think you read my text our of context.
I did not say that the universe is expanding at subatomic.
Although this process apllies to BBN and the matter and enery that is ejected from the centre of compact objects.
Also the red shift is in dispute because of the lack of understanding of the objects that create a flow of EMR from the source.

| Understanding the Astrophysics of Galaxy Evolution: the role of spectroscopic surveys in the next decade |

Abstract: Over the last decade optical spectroscopic surveys have characterized the low redshift galaxy population and uncovered populations of star-forming galaxies back to z ~ 7. This work has shown that the primary epoch of galaxy building and black hole growth occurs at redshifts of 2 to 3. The establishment of the concordance LCDM cosmology shifted the focus of galaxy population studies from constraining cosmological parameters to characterizing the processes which regulate the formation and evolution of galaxies.In the next decade, high redshift observers will attempt to formulate a coherent evolutionary picture connecting galaxies in the high redshift Universe to galaxies today. In order to link galaxy populations at different redshifts, we must not only characterize their evolution in a systematic way, we must establish which physical processes are responsible for it. Considerable progress has already been made in understanding how galaxies evolved from z ~ 1 to the present day. Large spectroscopic surveys in the near infrared are required to push these studies back towards the main epoch of galaxy building. Only then will we understand the full story of the formation of L* galaxies like our own Milky Way. A large near-IR spectroscopic survey will also provide the calibration needed to avoid systematics in the large photometric programs proposed to study the nature of dark matter and dark energy. We provide an outline design for a multi-object 0.4 to 1.8 micron spectrograph, which could be placed on an existing telescope, and which would allow a full characterization of the galaxy population out to z ~ 2. We strongly recommend a serious further study to design a real instrument, which will be required for galaxy formation studies to advance to the next frontier.

| The propagation of uncertainties in stellar population synthesis modeling II: The challenge of comparing galaxy evolution models to observations |
|
| Authors: Charlie Conroy, Martin White, James E. Gunn |
| (Submitted on 31 Mar 2009) |

Abstract: Models for the formation and evolution of galaxies readily predict physical properties such as the star formation rates, metal enrichment histories, and, increasingly, gas and dust content of synthetic galaxies. Such predictions are frequently compared to the spectral energy distributions of observed galaxies via the stellar population synthesis (SPS) technique. Substantial uncertainties in SPS exist, and yet their relevance to the task of comparing galaxy evolution models to observations has received little attention. In the present work we begin to address this issue by investigating the importance of uncertainties in stellar evolution, the initial stellar mass function (IMF), and dust and interstellar medium (ISM) properties on the translation from models to observations. We demonstrate that these uncertainties translate into substantial uncertainties in the ultraviolet, optical, and near-infrared colors of synthetic galaxies. Aspects that carry significant uncertainties include the logarithmic slope of the IMF above 1 Msun, dust attenuation law, molecular cloud disruption timescale, clumpiness of the ISM, fraction of unobscured starlight, and treatment of advanced stages of stellar evolution including blue stragglers, the horizontal branch, and the thermally-pulsating asymptotic giant branch. The interpretation of the resulting uncertainties in the derived colors is highly non-trivial because many of the uncertainties are likely systematic, and possibly correlated with the physical properties of galaxies. We therefore urge caution when comparing models to observations.
I was going to write a bit more, but I have to go, need to pick up the kids.

Re: Mystery of rapidly expanding universe solved.
The understanding of the EMR and it‘s sources, or light spectrum from stars and galaxies is not in question. It is understood quite well.

Re: Mystery of rapidly expanding universe solved?
G'day Dusty
What type of expansion are you talking about?
On the macro scale there is no expansion as a total universe.
On a micro scale there is no expansion as a total universe.
===================================
As for the ability to expand as a process via jets, thats normal.
As for expansion on Micro scale, degenerate matter found in compact object when ejected such as Neutron matter, quark matter and so on reforms and expands into atoms.

Re: Mystery of rapidly expanding universe solved?
Here is something to think about: Imagine the biggest Black Hole, so BIG that averything that can be seen recites inside that Black Hole, including other Black Holes. This gigantic Black Hole will be the one thats Expanding and the so called Dark Energy is the one that recites outside of that Black Hole. All else constitute empty Space but not so empty cause there are others Gigantic Black Holes that contain the same fabrics as our views of the Cosmo that is to say that everything is constantly reproducing from the very small to the very large. Our universe therefore, is being influnce from all directions but at the same time is being held by the same forces acting upon one another. All are keeping things in their respective places instead of random choas. To understand these ideas you need to expand your mind.....................................................................................

Hello Dusty
If we are living in an expanding universe.
Tell me what do you see that is expanding? Its not our Milky way, its not the local group of galaxies that M87 is the centre of, its not the cluster of groups of galaxies and its not the cluster of clusters of galaxies. Observations rule out any hyperthetical theory. The expansion that you talk about is spacetime and not actual distance.
Hello Fluflu
Good imagination.
The largest so called black holes are compact bodies that live in the centre of galaxy clusters. The largest being about 20 billion Sun masses. From these giant jet stream eject matter that is able to reform galaxies far far way in other galaxies.
Thes can can google for.

http://arxiv.org/abs/0709.2909 A Quantum Cosmology: No Dark Matter, Dark Energy nor Accelerating Universe
|
| Authors: Reginald T Cahill (Flinders University) |
| (Submitted on 18 Sep 2007) |
|
| Abstract: We show that modelling the universe as a pre-geometric system with emergent quantum modes, and then constructing the classical limit, we obtain a new account of space and gravity that goes beyond Newtonian gravity even in the non-relativistic limit. This account does not require dark matter to explain the spiral galaxy rotation curves, and explains as well the observed systematics of black hole masses in spherical star systems, the bore hole $g$ anomalies, gravitational lensing and so on. As well the dynamics has a Hubble expanding universe solution that gives an excellent parameter-free account of the supernovae and gamma-ray-burst red-shift data, without dark energy or dark matter. The Friedmann-Lema\^{i}tre-Robertson-Walker (FLRW) metric is derived from this dynamics, but is shown not satisfy the General Relativity based Friedmann equations. It is noted that General Relativity dynamics only permits an expanding flat 3-space solution if the energy density in the pressure-less dust approximation is non-zero. As a consequence dark energy and dark matter are required in this cosmological model, and as well the prediction of a future exponential accelerating Hubble expansion. The FLRW $\Lambda$CDM model data-based parameter values, $\Omega_\Lambda=0.73$, $\Omega_{DM}=0.27$, are derived within the quantum cosmology model, but are shown to be merely artifacts of using the Friedmann equations in fitting the red-shift data. |

Re: Mystery of rapidly expanding universe solved?
Fluflu, it's great to imagine things. Einstein said imagination is more important than knowledge. Nevertheless, imagination should lead us to something that agrees with known observations and data, not just in any direction we can cleverly imagine. For myself, it isn't difficult to imagine hundreds of could be scenarios, but that doesn't do anyone much good, other than myself. Imagination is what first led me to think about an alternative cosmology. At first, the idea wasn't too good, according to what is known about the universe. After a lot of work, I was able to hone it into something that agreed with the data as much as BB theory does, if not better.This isn't to say it is THE answer, as we just don't have enough observational data to clearly agree on this yet. It's just another answer.
Now if you can show how your idea fits with what we see, fantastic. I wish you luck with it.

http://arxiv.org/abs/0901.4169 No Evidence of Time Dilation in Gamma-Ray Burst Data
Authors: David F. Crawford (Submitted on 27 Jan 2009)
Abstract: Gamma-Ray Bursts have been observed out to very high redshifts and provide time measures that are directly related to intrinsic time scales of the burst. Einstein's theory of relativity is quite definite that if the universe is expanding then the observed duration of these measures will increase with redshift. Thus gamma-ray burst measures should show a time dilation proportional to redshift. An analysis of gamma-ray burst data shows that the hypothesis of time dilation is rejected with a probability of 4.4$\times10^{-6}$ for redshifts out to z=6.6. Traditionally the lack of an apparent time dilation has been explained by an inverse correlation between luminosity and time measures together with strong luminosity selection as a function of redshift. It is shown that the inverse correlation between luminosity and some time measures is confirmed, but using concordance cosmology strong luminosity selection cannot be achieved. It may be possible to explain the apparent lack of time dilation with a combination of gamma-ray burst selection, some luminosity evolution and some time measure evolution. But this requires a remarkable coincidence in order to produce the apparent lack of time dilation. However the data are consistent with a static cosmology in a non-expanding universe.
At the and of the day, I do not get emotional over which theory is correct. So I read to find what scientific evidence best supports what ever model.

Re: Mystery of rapidly expanding universe solved?
It is generally understood Harry, that it is spacetime that is expanding. Now while our local galaxies are not expanding away from each other, as they are gravitationally bound, on the larger scales spacetime is expanding. This you agree with?
Now, if spacetime is expanding and we are all part of the universe. (Galaxies that is) (Have you ever seen the expanding mesh example with little points on the mesh, and when the mesh is expanded by people pulling on it from it's sides, the little dots get further apart.) how can you reconcile this fact and yet say that galaxies are not getting further and further apart on the larger scales? How can you reconcile an expansion and growth of spacetime without an increase in distance of the objects residing within spacetime?
How can you reconcile that while the local galaxies that are getting closer to each other and show a blueshift in the light spectrum, the more distant galaxies are showing a red shift, which means that they are receding from us?

Re: Mystery of rapidly expanding universe solved?
First there is no such a thing as SpaceTime as far as Space itself is concerned. Space is an entity that has no dimensions and has to time cause it had no beggining and it has no end or ending. Science gets somehow confuse with what is Space and what is Time. Time only exist where elements and particle exist these includes all things that are observable within our reach of Space. Some hold to the idea that Space bends or that is warp that is totally false, what is warping or bending are the particles and elements which are occupying Space when these are interacting with one another along with other events. Again Space is not created nor can it be created, it has no Time --- it cannot be measure, you can only measure the objects that occupied Space from one point to another. You can't do that with Space cause there is no starting point or ending point. Another mistery about Space is that it has no Dimensions but it supports all others. To conclude you must think of all the things that SPACE IS NOT to find what Space is.

Re: Mystery of rapidly expanding universe solved?
fluflu:

That is inconsistent with General Relativity, which has been confirmed repeatedly by experiment and observation.
Space is an entity that has no dimensions
Since we exist in space, and observe at least three dimensions, then your statement is inconsistent with what we perceive as reality.
and has to time cause it had no beggining and it has no end or ending.
There certainly are those who will agree, and disagree, with that. Plenty of room for discussion on that point.
Science gets somehow confuse with what is Space and what is Time.
Not really, not since Einstein and the adoption of relativity as our worldview. In that worldview, space and time are linked. There is plenty of agreement on that point, and, again, it's been confirmed by experiment and observation.
... Some hold to the idea that Space bends or that is warp that is totally false ...
No, once again it has been repeatedly confirmed by experiment and observation. If you want some interesting reading along those lines, Google "frame-dragging" and "gravitational lensing" ...
... what is warping or bending are the particles and elements which are occupying Space when these are interacting with one another along with other events.
Can you cite a published and refereed reference for the above? As far as I'm aware, we have never observed matter warping or bending. However, there is the idea that this sort of thing happens near singularities (which have not themselves been observed directly, though they are believed to exist beyond event horizons). For interesting reading about the stretching of matter at event horizons near singularities, read Neil de Grasse Tyson's Death By Black Hole or Kip Thorne's Black Holes & Time Warps: Einstein's Greatest Legacy.
It is totally okay to disagree with these points. I'm just pointing out to you that you're swimming against the (considerable) mainstream tide if you do.

Fluflu may have a point. The point being that time has no identity.
Hello dusty, what you say is main stream thinking and I'm well awear of the logic. The problem i have is that when we observe the super clusters they have clustering and that the ajoining super clusters are bound by gravity. As for redshift data the errors within cannot explain the intrinsic properties of compact bodies. This will not be resolved for a number of years and to rely on the data to say it is evidence for expansion or acceleration is a mistake in science.

| Observations of type 1a supernovae are consistent with a static universe |
|
| Authors: David F. Crawford |
| (Submitted on 27 Jan 2009) |
|
| Abstract: Analysis of type 1a supernovae observations out to a redshift of $z$=1.6 shows that there is good agreement between the light-curve widths and $(1+z)$ which is usually interpreted as a strong support for time dilation due to an expanding universe. This paper argues that a strong case can be made for a static universe where the supernovae light-curve-width dependence on redshift is due to selection effects. The analysis is based on the principle that it is the total energy (the fluence) and not the peak magnitude that is the best `standard candle' for type 1a supernovae. A simple model using a static cosmology provides an excellent prediction for the dependence of light curve width on redshift and the luminosity-width relationship for nearby supernovae. The width dependence arises from the assumption of constant absolute magnitude resulting in strong selection of lower luminosity supernovae at higher redshifts due to the use of an incorrect distance modulus. Using a static cosmology, curvature-cosmology, and without fitting any parameters the analysis shows that the total energy is independent of redshift and provides a Hubble constant of $63.1\pm2.5$ kms$^{-1}$ Mpc$^{-1}$. There is no indication of any deviation at large redshifts that has been ascribed to the occurrence of dark energy. |

| Abstract: Supernovae and radio galaxy redshift data are fitted in an alternative cosmology. The galaxies are assumed to recede with unchanging velocities in a static Robertson-Walker metric with a(t) = 1. An exact fit is obtained with no adjustable parameters. There is no indication that the recession velocities are changing with time, so no call for "dark energy". |

Re: Mystery of rapidly expanding universe solved?
Although the originating point of many of the Gamma ray bursts are from distant locations, this does not mean that the gamma rays have stayed in their original form all throughout their travels. And now they have satelites that can quickly turn and see where these gama ray bursts have come from, and yes the light from these explosions is redshifted, so your information is out of date.
In regards to these giant galactic jets that you speak of that supposedly produce other more distant galaxies, can you provide us with some pictures perhaps from the Hubble that show such processes happening? I've never seen this. I'm not denying that jets exist, but I've never heard of such powerful ones that can create other galaxies, or seen them.
If you don't except redshift as an explanation, then do you also ignore blueshift as well? (that some galaxies are actually getting closer to us)
If the universe is not expanding, (say that it is at a standstill) and I'm sure that you accept gravity as a force, then what is keeping the universe from collapsing in on itself?

Re: Mystery of rapidly expanding universe solved?
Constant movement is keeping keeping the Universe from not collapsing in on itself. MOVEMENT had not been given is due place in physics and in cosmology. Movement is something that is attached to Gravity these two go hand in hand and keeps our planetary system in checked from not running away in all directions or flying into the sun. All of these bobies are acting upon one another and their rotations and evolutions all equal movements that compliments gravity or vise versa.
