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?

that's no current theory that I've heard of.

It's no more correct than assuming the dimensions outside our space-time aren't part of an entirely different kind of space time.

True.

Universe to expand forever, say NASA.

Yeah I'm waiting for NASA's official release to write this up for the main page.

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

4% now (see WMAP results)

I am starting to feel a bit irrelevant... I'm made of almost nothing of almost nothing.

And you only exist for almost nothing of the time the universe does.

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:

Welcome to the modern world of science!

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.

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)

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.

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

There is a new theory of other universes created at the time of the big bang; but the model predicts that one is 10^(10^28) (that's a 1 followed by 10^28 zeros) meters away, so it'll be quite a while before we can detect something that far away.

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.

Would these other universes be some what parallel

We can't perceive it, but we can make empirical predictions.

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.

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...

All we ever see or observe is ordinary matter...

Electromagnetic waves?

yea.

 

But as MrL mentioned, there is a certain horizon problem that prevents us from probing into it.
