Starship Asterisk*

Hello All

Looking back at the cluster of super clusters.

Where is the expansion of the universe and the Big Bang reference to it.

It seems to me that its moving as a unit.


I have made 4 posts and not one link have I posted.

Withdrawl symptoms

Thank Pete


Thanks for the link,,,,,,,,,,,,,my comp man said not to play with it too much
or else it will fall off. He probably means the hard drive.

Mozilla ,,,,,,,firefox,,,,,,,,,,,,,ggod stuff.

Whats the difference between a browser and search engine?.

Try a different browser, like Firefox! [url]http://www.mozilla.com/firefox/[/url]

(didn't know you had a search engine, harry :wink:)

Hello BMAONE23

There is something wrong with my search engine.

Have to get a comp man.

Harry,
Do check your settings. I just tried it and had no problem.

Hello All

Hello Coloradosky.
For some reason I cannot open your link. In actual fact for the last 12 months I cannot open that link.

Must be my explorer or settings or a Black Hole over my computer.

Harry I enjoyed that link very much. And the animation really helped.

I did not realize that the Milky Way was in a relatively sparse region between superclusters, and that the Centaurus-Hydra supercluster is winning the "tug-of-war" on the Milky Way!

According to wikipedia, the Great Attractor resides 250 million light years from the Milky Way, in the direction of the Hydra and Centaurus constellations. http://en.wikipedia.org/wiki/Great_Attractor

I'm trying to visualize this ... according to the google calculator 250 million LY = 77 Mpc, so the Great Attractor is just out beyond A3581, I think :-p

Hello All

Hello doum,,,,,,,,,,,,yep the known visible stars,,,,,,a tiny tim bit of the endless universe.


Our galaxy is there by chance. Or maybe our intruments where made on earth and favor us being central to all. Or maybe we are self centred people.

Qev you are right about the scientific theory.

Its just that I'm a Big Bang Banger.

Um... we're [b]always[/b] at the center of our observable universe. If you can see a set distance in every direction around you, you're going to end up in the middle of a sphere of everything you can see, by definition. It doesn't mean anything more than that; it's simply an artifact of the very nature of three-dimensional space.

To interpret it otherwise would mean that, as an example, standing on the surface of the Earth, that the visible horizon forms a circle around you means you're standing at the center of the surface of the Earth?

Also, I have issues with the phrase "only a theory" used to play down the significance of any scientific theory. [b]Everything[/b] in science is a theory, because nothing, [i]absolutely nothing[/i], outside of pure mathematics, can be unequivocably proven true. Relativity? It's a theory. Evolution? It's a theory. The Big Bang model? It's a theory. The 'Laws' of Thermodynamics? That's a theory too.

The word 'theory' has a different meaning in common usage than it does in science. In everyday speech, it seems to imply a vague, unfounded speculation, while within scientific disciplines, a theory is a predictive model with good observational evidence supporting it. You might be confusing the term 'theory' with the term 'hypothesis'. They're not the same thing.

Harry, I think it is not all the known stars. It is the known star in a radius of 80 Mpc (Wich is a small part of what we can see in the universe). If u look in the animation in the upper page ull see some more picture with different radius (Like 30Mpc, 60Mpc,120 Mpc and even 240Mpc.). And these spheres are simply the radius at wich they look at this tiny part of the univers. If u look at all those different sphere of radius ull see no major change in the distribution of mater. So we lie in the center of what we are looking at. And the super cluster are not that round. I think. :wink:

I find it ineresting that this super cluster is apparently shperical and that WE lie at its center. Possible evidence of a small bang which would have followed the big bang. It looks like we ARE at in the center of our small big bang after all.

Big bang delivers matter outward but no light yet (billions of years later) small bangs cause this matter to be further flung out but the secondary bangs cause light to "be" making the visible universe.

Nice one Harry.

BBT is only a theory based on Hubble's constant which was based on doppler effect. Even if BB did happen, the universe could still be much larger than what BB accounts for i.e it was only a small bang in a much larger picture.

Hello All

I have been trying to look for this link for some time

http://astro.uwaterloo.ca/~mjhudson/research/threed/

This is the known galaxy with the super clusters.

The more I see this image the less I think that the universe is expanding and the less I think of the Big Bang. Not that I think much of the Big Bang, only that its a theory.
