Sayonara Posted February 10, 2003 Share Posted February 10, 2003 Originally posted by fafalone The current big bang theory states that there were multiple points. So you're just assuming that's correct? If you don't believe that could have happened due to the lack of 'space' between the points, and therefore their lack of attributes defining them as separate points, why assume that's what happened?

Radical Edward Posted February 10, 2003 Share Posted February 10, 2003 that's no current theory that I've heard of. Link to comment Share on other sites More sharing options...
fafalone Posted February 10, 2003 Share Posted February 10, 2003 It's no more correct than assuming the dimensions outside our space-time aren't part of an entirely different kind of space time. Link to comment Share on other sites More sharing options...

DocBill Posted March 19, 2003 Share Posted March 19, 2003 Originally posted by fafalone Don't forget, conventional matter only makes about something like 30% of the total mass of the universe. at the last meeting I was at (Jan, 2003) it was down to 8-10%. Not much. Bill Link to comment Share on other sites More sharing options...

XxSuprNovaGrlxX Posted April 5, 2003 Share Posted April 5, 2003 Originally posted by the GardenGnome Are familiar with dark matter? It is not known to what is it but it is said to occupy most of the universe. Sounds to me that with no sense of what dark matter really is, that the intention of this being a so called explanation is one that gives an easy outlet to "understand' the unimaginable:shrug: Link to comment Share on other sites More sharing options...

Skye Posted April 6, 2003 Share Posted April 6, 2003 Dark matter does seem a little dodgy. If my bank told me that no, 96% of my money wasn't all missing, it was simply dark money now I think I might be a little pissed at them. Wait...a little more pissed at them. If the universe started from several points, wouldn't the several points already have space(-time) between them? Maybe it had the same kind of space-time as is outside our universe. If so, I hope whoever owns that space-time doesn't have a concept of property rights. Link to comment Share on other sites More sharing options...

Maybe it had the same kind of space-time as is outside our universe. I don't think this is the case, nor have I ever heard of the big bang occuring in several places (expect for "everywhere" since it created space/time too) Dark matter is supposed to be supersymmetrical versions of ordinary matter, such as WIMPs (Weakly Interacting Massive Particles) and configurations of normal matter aka MACHOs (MAssive Compact Halo Objects) Link to comment Share on other sites More sharing options...
Poena Posted April 25, 2003 Share Posted April 25, 2003 Just a question (pardon me if I show any display of ignorance)... but: Isnt there a theory (its name I do not know) about multiple universes created by big bang, that they all touch at a certain point with our universe-- (which would give an idea to some what was 'outside' it) Or was this bullshit that was fed to me years ago? I dont remember it all .... nor believe it. Link to comment Share on other sites More sharing options...
mastersamwise Posted May 11, 2003 Share Posted May 11, 2003 I would imagine the edge of the universe to be a nothingness at an energy level of 0 (the minimum ground state for a particle is 1) therefore there is no particles of any sort, and if E=mc^2 holds then if there is no energy there is no matter.....if relativity works in a void that is Link to comment Share on other sites More sharing options...

Physics5000 Posted May 13, 2003 Share Posted May 13, 2003 It is impossible to precieve what is beyond the edge of the universe being that we can not observe and nothing can exist beyond the universe, beyond space and time. Link to comment Share on other sites More sharing options...

fafalone Posted May 13, 2003 Share Posted May 13, 2003 Beyond the edge of the universe should be observable since ordinary matter continues to pass into it... it stands to reason one day we could send a probe into it. Link to comment Share on other sites More sharing options...
JaKiri Posted May 13, 2003 Share Posted May 13, 2003 What are you talking about? The empirical edge of the universe is what we can see (ie limited by the speed of light), which is less than it's total volume... Link to comment Share on other sites More sharing options...

blike Posted May 13, 2003 Share Posted May 13, 2003 yea. But as MrL mentioned, there is a certain horizon problem that prevents us from probing into it. Link to comment Share on other sites More sharing options...
