I wish I undestood more of this.... it seems very interestingly crazy!!!! awesome! where did this come from? There is only a link to the picture that I've found. btw, if you haven't seen "The Universe" on the History channel, check it out. Very well done! Why is it shaped like a pint glass? After the big bang, there was a super expansion period, which gives the picture the 'bottom'. the expansion slowed, it became more regular and the expansion gradually gathers pace as the matter becomes more separated, and the effect of dark matter becomes stronger. Or something like that. They made the calculations, by finding where things were, and working their way backward. They also calculated how they expected things to continue. my problem with the illustration is that it is not really 4-D at all. The intial outburst of galatic material only travels in 'one' direction? Since when? I think the way they explain it is twisting of the axes so a three dimensional graph shows the 'dimensions' 2,3 and 4. I have to admit there seems to have been some artistic license taken with the galaxies, and the title was the only way I could think to describe the picture. The original site is Smoot group cosmology http://aether.lbl.gov/ i think it's pretty cool. Very brief, clear perspective of the universe. thanx for the upload. Wouldn't the 4 dimensions shown here be length, width, height, and time? Our brains work in three D, and while we see in three D, our minds relate time to the change in the pictures, but we cannot see time. One thing we can do to to try and visualize it is with a geometric representation, which can provide enough of a link to extend our concept of dimension. Trying to get hour head around it can twist your mind a bit, but there is also the fact that to be displayed on a flat screen, it can only be seen in two D, I must also add, that while the picture and the logic are great, the way we see the evolution of the universe, is still a theory. There are too many things we are unaware of, but learning is an ongoing process. The big bang isn't real. No one knows anything about the "REAL" Universe, because no one has ever ventured there themselves....only telescopes where we can take pictures and do "calculations". No one has ever traveled farther than the moon. The REAL Napster, the outburst travels in the direction time flows (duh). yusukeshonen, you are an idiot. The REAL Napster, the outburst travels in the direction time flows (duh).NO....really? The problemn I had with the poor illustration was that it presents the outburst in a motion traveling only to the right. Last time I checked, unrestrained explosions in space tended to go in many different directions, not just to one side or the other. (duh) If that's the view of the universe- where am I? dear real napster------the big bang did not occur as "an unrestrained explosion in space", it was the event that CREATED time and space. this is a common misconception laymen have about the big bang, that there was something there already, even empty space, and that the big bang blew up in it. there was NOTHING there before the big bang (a concept that even the most advanced physicicsts and cosmologists have difficulty conceptualizing. think, really try thinking, of "nothing") and the event called the big bang created time and space. therefore the diagram is correct, to the left there is nothing and space and time proceed only to the right, in the direction of positive time. (duh) le...
