1. Diameter of our galaxy
2. Speed / Direction of Sun Through space in relation to the Galactic Plane
3.Distance of nearest stars following a simular "route" as our Sun
4.Projected values of "gas clouds" i.e. lifespan, density, elements, size, location

Those are excellent questions.

Properties of the Milky Way
Diameter of the Galaxy 90,000 ly
Length of the central bar 25,000 ly
Distance of the Sun to the Milky Way centre 26,000 ly
Orbital Period of the Sun around the Galaxy 225 my
------------------------------------------------------
In 80my we travel 128 degrees (0.356) around the Galaxy. The stars in the Galactic plane travel at about the same rate. It is the Solar Apex Group of variable giant Blue stars dragging the hydrogen (and dust) with them that cause all the fuss. Na, the solar apex star momentum are a aggregate of heavy core material and the hydrogen dust. They are so huge, they do not survive the transient of a single arm (10My). Thus, the high elipsoid indicates the relative mass of the heavy core materiel and hydrogen (edited 2006 OCT 05)

Item 4 may be estimated using Reference One in he original script.

lifespan: possibly 200my.
density: 0.264 atoms per cubic centimeter. 
elements: Helium and Hydrogen  
temperature: 6000C     
direction: On a heading out of the galaxy spiraling with and across the Suns Galactic Orbit.
size: estimated at light years across.
location: We are presently within a dust stream.

"There are only 0.015 helium atoms per cubic centimeter." Earth's atmosphere at sea level, for comparison, is a thousand billion billion (1021) times denser. And, finally, the velocity of the stream is 26 km/s or 58,000 mph.

Qualifiers: The Galaxy is defined by continuous hydrogen out-flow. It also is impacted by hydrogen packets, which I believe distorts the structure by adding arms, which then disperse under normal normal out-flow. The outflow is the Neutron radiation from the stars and the central bar. As you know, free neutorms have a 12minute half life, decaying to protons (hydrogen).

The OZONE protects us from UV radiation. UV radiation is particularily dangerous to DNA, among other critical carbon based organic structures. The OZONE when taken down to One Atmosphere would be only 5mm thick. So, it is a particularily vulnerable to depletion, with large disasterous consequences.
Most of what you need is embedded in this paper. If you read it all, you will be well informed. Look at all the references and links posted.

Oh, and mr_magazine, I am trying to keep this subject as compact as possible. It would offend no one if you erase entries as they become obsolete to your experience level.
--------------------------------------------------------
And, if you find contributing information, I would be very happy to include and even modify the Hypothesis come that may. MaddCow is my witness on that accord.

THANKYOU FOR YOUR ATTENTION.

Just could not resist one time, having found the Canadian Geological Survey of the hydrogen (using CO2) mapping of the Galaxy. The Galactic Geologic Hypothesis is in complete agreement with this map, and adds further detail.

I like these guys, does anybody want to see the Star Trek Overlay? ALways wanted to see what the scales were to various empires.

Now that one I do like Morbas. It is an interesting topic you have here. I studied Palaeo Anthropology at Otago University and although it does not reach back as far as you have in terms of time, the thought of what you have suggested is food for thought

 

Cheers for that

Thank You, glad you enjoyed it.

Cool, that map also meshes fairly well with the Galactic Habitable Zone (GHZ). I think that the GHZ was only defined recently, so the Star Trek galaxy was ahead of it’s time.

Although I personally believe that if interstellar conquest ala the Star Trek variety is going on, the central bulge would be considered prim real-estate. There might be a problem for new planets and life forms there, but I think that a great incentive to control the Super Massive Black hole and other exotic environments and materials that exist there would cause empires to claim this space.

The Star Trek map, and the habitability zone overlay seem to miss the idea that once developed, civilizations that can go from the Alpha to the Delta quadrant might find it advantageous to have large populations planted into whatever habitable locations are in the bulge.

Stars4life, I looked up the image source. www.solstation.com. Copied some of their stuff. Thank you for the direction and compliments.

-------------------------------------------------------

The habitable zone proposal restricts the region of life.  The Galactic Geologic Interval proposes that intelligence cannot compete with brute force until technology leverages the force of nature. By example, the clovis point allowed mankind to dominate the environment of manmouth beasts 15,000years ago. The 15,000 year ice age has coincidence with Northern Hemisphere winter alignment with Earth's furthest point from the Sun. It also may be aligned with Galactic Arm dust as we entered the Orion Arm, making that ice age much more intense than others before it, up until 65mya. Na...The mini ice ages are responsible for this (Edited 3 OCT 2006).

We are looking for signs of life where life intellect is using radio technology. If this is 1) a short technological period during the rise of intelligence, which is 2) only along the leading edge of the arms, then SETI success would be very improbable. For, we have just reduced the area of SETI Radio opportunity to the edges of the arms within the Habitable Radius of the Galaxy. This would translate to roughly a 1/72,000 factor in the equation of intellectual life radio opportunity (optimistically assuming a 1,000 year radio ON time). In addition a 1/2 factor due to the habital zone area reduction should multiplied into the equation.

I have noticed that introduction of the habitability zone into the Gallactic Geologic Interval Hypothesis  (GGI-H) thread before (Archive GGI-H). If it your intent to have me integrate SETI results into the hypothesis. Do you think it is supportive or critical to GGI-H ?

I am reviewing glaciations, and have an intersting correlation to share.

The present chill (Ice Age) began about 2 to 3 Ma, which according to the GGI-H, is about the time we entered the Orion Arm. Infact, according to NOVA (and probably  the USGS "The Great Ice Age") 36,15 and 3mya are ages since glaciation events since the KT boundary 65Ma. I will not maintain causual to the 72M period of the GGI-H because Ice Ages (like the one we are in) are linked to plate tectonic land mass arrangments more so than anything else. However, the Illinois State Museum Ice Ages quote is " These glaciations are not randomly distributed in time. Instead, they are concentrated into four time intervals. Large, important glaciations occurred during the late Proterozoic (between about800 and 600 million years ago), during the Pennsylvanian and Permian (between about 350 and 250 million years ago), and the late Neogene to Quaternary (the last 4 million years). Somewhat less extensive glaciations occurred during parts of the Ordovician and Silurian (between about 460 and 430 million years ago)."

Glaciations during the Pennsylvanian through Permian runs during the GGI-H infered high hydrogen inflow period. These help the hypothesis about the Mississippian(320Ma), and Silurian(408Ma) extinction exceptions to the 72M interval.

After reading Astronomys article, I wanted to know the location of these stars that will be grazing/entering our ORT cloud. Here is a picture of where they are relative to the direction of the Galactic Core. Looks like a fairly random dispersion in the Galactic Plane. This star map doesnot have Gliese710.

I am now looking into DLBlanchard theory to understand this integrated approach to extinction cycles. The diagram above shows a very interesting astronomical coincidence. That the Galaxy pulls the solar plane, and this rotates the angle of  Earth spin relative to the Sun plane of the ecliptic, also changing the elliptical poles of our seasons. This claims an 190my interval period. However, the datum used for this paper is not based on the present model of the Galaxy. We orbit the Galaxy every 220my, Blanc proposes 380my. Is there a more recently compiled paper on this, one that includes the correct Galactic Structure? Perhaps a NASA model on the plane of the Ecliptic alignment as the SUN moves around the Galaxy?

I think he is proposing that the aphelion is always alligned with the Galaxy center. Thus we have an assured worst case winter (thus Glaciation and Weather extremes) as the Earths tilt is constantly 23.5 degrees to the ecliptic plane, with the North Pole tilted away from the SUN (North hemisphere Winter), with the Galazy Accentuating the aphelion. (Aphelion is the furthest point from the SUN).

So how can this be if the ellipsoid has a 15,000 year precession between aphelion and perihelion alignment of the North Hemisphere winter? I don't think it is possible.

What may be possible is a worst case by chance alignment of the perihelion and and the Galactic Center. How much of an effect is unknown to me at present.

So why are the periods aligned to the arm intersections, and not eons, eras or epochs?

Epoch is the smallest of the geologic divisions, bounded by weather changes such as Ice Ages. Perhaps local environments such as major lakes. " The Epoch's specify conditions related to that particular time".

Periods specify life form types. Here we have divisions that are extinction driven, as major life forms are replaced by next generation (evolution). Extinction is a evolution driver, as most life forms tend to dominate and stabilize through competitive dominance. Extinction events eliminate dominance, allowing more meek or adaptive (and intellegent life) to establish dominance. That is, as dominance is established, life forms tend to larger size,  competing between them selves. So when the next extinction event occurs, the smaller size survives. I would argue, that the diseases spawned from each period, also favor re-emergence of equivalent life. This I might argue, is how life evolves through extinctions, rather than restarting from scratch. The Permiam extinction eliminated 95% of all life. Yet evoluiton advances across it. Another causual effect might be linked to the general increasing Sun temperature favoring different life type re-emergence. But I favor disease driven evolution across extinction events, as it transports more dna information, albiet indirectly.

Epochs and Eras are groupings of Periods. Thus these intervals are divided at  Period boundaries. Thus, in the GGIH, extinction intervals are closely associated to periods.

 

 

Looking over the impact crisis datum, I have plotted the time line for craters larger that 10km in diameter out of a population of 172.
http://www.unb.ca/passc/ImpactDatabase/CINameSort.html
I get clusters at 65mya (about 13), 150mya (about 6), 220(about 3) and 350mya (about 5). The 10KM diameter was a WAG at suppressing the young age, as smaller diameter would dominate the close in (young) time line. Hmm, these align with four arms, having a 74my common denominator.  The missing intervals would definitely throw off a metereorite based theory. Get back to you after reading this book:

Rampino M. R., Haggerty B. M., and Pagano T. C. “A Unified Theory of Impact Crises and Mass Extinctions: Quantitative Tests.” Annals New York Academy of Science, 1997.

 
-------------2005JULY22--------------------------- 
Meteorite impact datum,
( http://www.unb.ca/passc/ImpactDatabase/CINameSort.html ) plotted  at 5M resolution from 0 mya to 540Ma, shows a 74M interval.  A sum of R^3.5  during 35+/-10Ma is 1.5E6, during the 65Ma is 5.8E6, during the 145+/-10Ma is 290E3, during the 213 +/-10Ma is 960E3; during the 286+/-10Ma 33E3; during the 438+/-10 Ma is 14E3; during the 505+/-10Ma is 6.2E3. Noteable small peaks at 170 +/-10Ma, 408+/-10Ma and  at 470Ma are inter-arm events. The energy peaks taper off with time which could be erosion and unfound craters. Well, that hits Perseus, Cygnus, Shaver, Scutum-Crux, Orion intercepts fairly well, on 74M intervals. Exception is the Sagitarius intercept, which like the Permian intercept is low on crater frequency. Proportionality is given by Volumn=Energy^0.849 in cratering. Since we are only interested in relative energy, simplified true proportionaliy is R^3.5<=>E. The biggest hits occurred about 2 billion years ago, of the class of Yucatan(190km), but larger(250km and 300km). WOW.
I remember that a crater in Australia was dated about the Permian extinction time; this datum shows only two small hits. Anybody have datum on this? 
-------------------------------------------------------
This shows an 74M GGIH periodicity. My opinion about Meteorite extinction smoking gun, is that it is not the driver, just a possible contributor. 
------------------------------------------------------- 
Preliminary Results: Three mathematical intervals of significant meteorite energy sums, a) 30M in resonance with Solar system Galactic Plane intercepts, b) a 50M unknown, and c) a 74M in proposed Solar system intercept resonance with the Galactic Arms. The chart is the result of a search algorithm for periods from 1 to 300M, and for time intervals 1% to 20% X period, using a 1M scan resolution for summing the impact energies. Four time intervals were shown for clarity, and are representative of the set. No attempt to provide a subtractive data base was made. Later subtractive analysis indicates that the 50M year cluster is significantly associated with 74M year period meteorite datum. The 30Myr period is not significantly associated with the 74Myr period meteorite datum. (Na, the 30My period appears to cause some of the 74 My deviations 2006 OCT 05) The 50Myr cluster appears to be an alias.

The GGIH 74M period and associated 34M harmonic at +/-1M offsets. The 30M period could be the intercept of the solar system with the Galactic Plane. And the 50M period is alias ???
------------------------------------------------------
Edited 2005AUG14 Figure 3 Chart Added

Edited 2005AUG24 updated the 72M periods to 74M period.

-----2006MAR11-----

Two periods were looked at with 10%*Period averaging. That is a accept time of +/-7.4M yrs for the 74M yr period and +/-2.9 M yrs for the 29M yr period.

The 74M period centers at -8Ma, with a width of 8M years. So it appears that we are entering the Orion Arm asteroid threat.

The 29M period centers at -23Ma with a width of 4M years. So it appears that we will be the crossing of the Galaxy Plane asteroid threat in +23 +/-2 M years. This supports with http://solar-center.stanford.edu/FAQ/Qsolsysspeed.html . The meteorite datum suggests we crossed the Galactic Plane 6+/-2Ma, not the 2Ma they estimated. Also, they indicate that it is the dust of the Galactic Plane that obscures our view of the galaxy. It is the Orion Arm dust that obscures our view.

Fascinating plots, look like a bandpass response on both these functions. If anyone requests, I can post these here.

I hate to tell you this...

This chart can be created from my data. Rates a copy Eh....ASTRONOMY!

Oh, would I like a big copy of this chart. WORKING on this....

No need to be rude or anything, but who in the world has time to read all that. I bet there isn't a single person here who read it all word by word. Good posts by the way!

Now that is where you are mistaken.  I have read this thread from begining to end and find it very intriguing. It may actually hold the answers to events that occurred on the planet in the past. Keep it up Morbas!

space_man: most gracious for your comment.
But, I do suspect you are correct. Anybody else ?

This is JPLs newest version ot the Milkyway Galaxy. They have just recently found that the central bar is 27,000 LYrs (not 20,000LYrs). See this at http://www.space.com/scienceastronomy/050816_milky_way.html . This is newly developed technology confirming the Galactic shape as referenced at http://www.ldps.ws/Mirror/Universe/milkyway.jpg. My applause to the young scientists that make it happen !

And now astronomy newsletter has another measurement of the arm

Spitzer Space Telescope, our galaxy's center harbors a bar of stars, dust, and gas measuring 28,000 light-years long

'at about the same distance of the Earth from the core'

Of course, The Royal Astronomy has this to say about the distance of the Earth from the core.

Arches lies 25,000 light-years from Earth, and sits just 100 light-years from the galaxy's center.

I have lost the source to this quote....

Well, a +3 Myr change in the Arm length equates to about -1 Myr change in the inter-arm spacing. A discrpancy of 3Myr  is not significant. JPL's placement of the solar system is suspect, given the measured hydrogen mapping of the Galaxy in reference [18] http://www.ldps.ws/Mirror/Universe/spiralmap.gif shown in the above reference section. It shows a more clearly defined Norma Arm, Scutum Crux, Sagitarious, and Orion than this artists drawing gives.

And this thread has reached 4,000 views. Cannot say these are all different readers, cannot even say a portion of these weren't my edits. 'What say' Astronomy should make these statistics visible, eh. What I can say is if this were an article in the magazie, that represents serious interest, and possible newstand sales.

Three arms appear dependent on Hydrogen Influx intensity that I have labeled Permian, Missipian and Silurian. And some evidence has been presented that another mid arm extinction occurred some 34 My (million years ago). This indicates a mid arm accumulation of asteroids, that in a hydrogen rich inflow condition would appear as another arm.

A formal naming convention provides a common way of communication. The four major arms and the two additional permanent arms are named after fellows, and those that discovered them. These arms also overlay with extinctions. Like the events they are, the temporary intermediate arms should be called by the extinctions they coincide with.

Having uncovered an unknown characteristics of the hydrogen/helium dust cloud; With it having a outward arc and relative velocity of 26Km/sec, a critical piece of the puzzle has been found. With regards to Webster’s definition of Theory, I am about to up the level of this proposal to Theory. The Galactic Arm dynamics will be revised with deeper discussion on hydrogen flow origin and directions. (This will be about 6 months.)

Does anybody see any further missing logic, facts etc. that appears to be missing?

Well, another article by American Scientists portrays the Sun between the Orion and  Sagitarrius Arms,...

http://www.americanscientist.org/content/AMSCI/AMSCI/Image/FullImage_200342893945_546.jpg,

this image is suspiciously close to the JPL aberation of the Galaxy. Lets see, Sun is 26,000ly from the core. Average Arm spacing is 4,500ly, Ok looks like that Arm spacing is about 4,500ly (74My = 4,500ly / 24Km/s). Geometry is in error, the Orion Arm spurrs from between the Sagitarrius and Persius Arm, starting almost evenly between them according to the Hydrogen Mapping [18]. It is a minor arm, not major as shown on the American Scientists diagram (drawing). I have emailed the author of this fine article, and asked for source data and links for this drawing. We will wait and see.  What I indicated was that the Arms are demarcated by hydrogen congruence, clearly a fact revealed by the article that we are in a huge hydrogen/helium flow, (26Km/s from the direction of Ophiuchus Constellation). ERGO, from the general direction of the Galaxy Core.

The IAU should register the name/structure of the Arms.

 

Recent uncharacteristic flare(s) observed on Barnard's Star, if occurring on the Sun, could eliminate the OZONE on Earth. Depleted OZONE would allow UV to eliminate life forms that are too large to hide under stones and in caves. In short, a Geologic Period termination level event. These flares are outside of Barnard's Star, characteristic age mainstream, so they make news. Could it be I wonder, caused by planetary sized asteroids? Iron debris from supernovae. Earth's meteorite history has a slight periodicity in sync with Periods (74MY). This could indicate our SUN (a far greater attractor than Earth's meager gravitational field) is a likely contributor to Geologic Period terminations. Any Galactic debris will more likely hit the Sun. Anything with sufficient mass and velocity to penetrate the Sun's surface, would stir the Sun's interior, causing a large release of energy (Super Flare). Just perhaps, increased solar flare activity is caused by these events. Some of the above references are researching a Super Flare extinction connection.

I reviewed the direction of the nearby stars with Flare Activity, and find only locality. We are a group of star based systems in the Orion Arm, so that causality is possible.[8]

 

The Australian impact is reputably to be 120mi diameter. This link is my first notice about the impact crater. It is still preliminary tho...still a unconfirmed and undocumented find.....

http://www.cbsnews.com/stories/2004/05/13/tech/main617297.shtml

"Australia's northwest corner. They're calling it the Bedout crater (pronounced Beh-doo.) "

 This would add to a 74MY interval with a 32MY offset. Have not added this into the frequency analysis...awaiting confirmation and documentation...
