so if the big bang did happen whats the universe expanding into? what is the defining point to the edge of the expansion cloud?
Did the big bang have to be all encompassing or couldit have been a local event and the rest of space and time already existed around our little cloud and could that be why we cant see outside our expansion bubble ? due to distorsion due to heat and shockwaves?

lets keep this on physics this time with no pointless cack on religion . your faith is yours keep it to yourself i dont want to waste my time listening to it. get lives and partners and grow up.

the universe is expanding in to milk, billions and billions of gallons of the stuff.

Since nobody can prove anything else, my theory is just as likely as anybody elses.

Ideas about the origin of the universe are not subject to the scientific method (cannot be observed, repeated, tested,etc).

Noone can know for sure what happened because none of us was there. The Big Bang hypothesis is a philosophical (religious) idea.

People who believe in the Big Bang have a huge faith since the observed evidence does not support it at all well.
Many people who believe the idea are perhaps not aware that one of the *assumptions* of BB cosmology is the Copernican principle. One of the consequences of this is that the universe is assumed to have no centre and no edge.

So to a BB follower, since there's no edge it makes no sense to ask what's outside.

On the other hand, some believe that the evolutionary assumptions are false, the universe was created, and there is an edge. Beyond the edge we might as well call nothing since it is beyond our comprehension.
Belief in a creator is no more religious than belief that the universe created itself out of nothing. It is a good deal more credible, and requires less faith :)

"Stephen Hawking and George Ellis have written: ‘…we are not able to make cosmological models without some mixture of ideology’. Their work makes use of the Copernican Principle: the universe has no edges and no centre—it looks everywhere broadly the same. This principle, it is important to note, is not a conclusion of science, but an assumption thought to be valid."

The Big Bang was not an explosion with a leading edge. It is an expansion of space itself.

An analogy may be in order. Model spacetime by a
sphere with time being represented by going down
a longitude line and space for a fixed time being
represented by a latitude line. The Big Bang would
be represented by the north pole. In this model,
space expands until we get to the equator and then
starts to contract again until we get to the south
pole, which represents a 'Big Crunch'.

Now ask what space is expanding into. By
looking at our model, we see the question is either
meaningless, or just has the answer 'into the future'.

In the real world, the spacial part is three dimensional,
not one dimensional like in our model (the circles of
latitude). Also, it is likely that the universe
will expand forever, so instead of a sphere, a
trumpet shape may be more appropriate. But the actual
models used by scientists are generalizations and
elaborations of models like this toy model.

Your comment simply demonstrates that you haven't got a clue what you are talking about. Where is your evidence that the Universe is shrinking? You haven't got any because the evidence doesn't exist.


For your information, the expansion of the Universe is actually accelerating. This is a demonstable and proven scientific fact. If you can't be bothered to do some research and actually LEARN how these facts are arrived at, I suggest you refrain from making such facile remarks in future because it makes you look like a complete ignoramus.

The big bang did happen - all galaxies are moving away from each other at high speed, so it follows that at some point in the past they came from a central point.
Space and time did not pre-exist the universe - they are properties of the universe itself. The big bang was not the creation of matter at a point in space, it was the creation of space, time, matter and energy - in other words everything.
It was not a local event, it was the only event. We can't see outside the universe because the universe is everything by definition.
As for what the universe is expanding into - this is a category error - it could just as easily remain the same size while everything within it was shrinking - we wouldn't know.

the universe is expanding into nothing. I know it's hard to get your head around, but that's how it is.

There is nothing outside the universe (according to the most popular and widely accepted theory of the big bang). The universe creates space as it expands. It is not creating more matter, more the matter is spreading out to create more space. As the edge is the same as what's in the middle, dark matter and some normal matter. Sure we could be in some bubble with who knows what outside, but nobody knows. We could all be figments of our own imagination, or that of some evil green monster, so ???

But it seems most acceptable that there is nothing there. You are probably one of these people who can't imagine this, there being nothing - you see nothing as a space to be filled, it's not. It's not there, it's being made as the universe expands.

Outside the universe there is nothing, and so there is no 'outside' or 'inside' there is just what there is.

Dear Sir:

Having read most of the theories about the origin of the universe, I feel fairly confident in saying that the big bang idea did happen, or at least something quite similar happened. The main proof for that is that everything in our Galaxy seems to be moving outward away from some central point. So, if you work the idea backwards, at one point all of this stuff was rather centrally located. Then something caused it to shoot outwards. Whatever it was was huge by any standard of measure you want to come up with.

Now, the reason we cannot see past a certain point has to do with equipment technical limitations. Ian Ridpath, author of ASTRONOMY, DK Publishing, NY, NY, tells us that we, on Earth, are at the center of an "observable sphere" that has a radius of 40 Billion Light Years in every direction. "Observable Sphere" means that using the most advanced equipment we now have available to us, we can "see" things out to a distance of about 40
Billion Light Years. Beyond that our equipment fails to give us any useable information. So we can't see any farther than that.

Take a few moments and try to write down, using pen and paper, the distance in plain MILES that is equivalent to
40 Billion Light Years, without using any scientific notation like powers of ten, or AU, etc. If you honestly try to do that,
you will come up with a distance that boggles the mind it is so huge. And, what is important is that this is not the END. We just can't "see" any farther because our equipment fails at that point.

In a practical sense, things beyond 40 Billion Light Years are so completely remote to us that they really are immaterial except for those wishing to delve into the hypothetical and wallow around in the Maybe's and What If's endlessly. No one has been there. No one is going there. No one knows for sure. So it is all a big guessing game. Unfortunately for us, on Yahoo, it seems like the one that asks the same question over and over and over again seems to get the largest audience and that person never looks back at information provided to others on the same topic. So the drivel goes on forever... My appologies for crying in my beer...Wouldn't it be nice to hang this answer up for everyone to see before they asked the same question again? The average person cannot comprehend distances as great as those in Space. And, unfortunately the next words out of their mouths is, "Well what is beyond that?" My response is, "Who the heck knows?"

OHHHH!
michael … Your so rude, first of all i never suggested it where in the first place, and if you want to get all tecnofreeky on me you imbecile, i never suggested it where slowing down either. never-mind your so-called research pal. if i where to go on off one, people like you would simply go, period. Now why don't you go and read the others comments here, then read my comment, don't go off on a Wonder of research, lets just stay here shall we and keep things simple for others benefit! NOW!! i never suggested it where not accelerating, i said quote, its slowing down, now that has to be a relative measurement and both with considerations to the very simple fact my dull friend "that its the acceleration that's slowing" go do you maths and get back here and tell me I'm wrong!

Didn't you pay attention to the end of the movie "Men in Black"? Out entire universe is inside some marble being used by an alien in a game.
Seriously, there's membrane or "brane" theory and a host of others out there speculating about what is outside. And yes, like you stated most religious people say this is where "heaven" is located. Who knows..who really cares? We can never interact with anything outside our universe, since soe theorists say if we did, our laws of physics wouldn't hold up outside our physical universe. So, if we did get outside, what would hold us together?
The "big bang" caused the expansion of spacetime itself, not its creation or making. What spacetime is expanding into is anyone's guess. Like the first answerer stated it could be milk. Got cookies?

The use of a balloon being blown up more an more is a poor analogy. Space/time is much more complex. A simple response though, as to why we cannot "see" outside our "bubble" is that no light is eminating from there.
