People say space doesn't have and end. But everything has and end? Doesnt it?

Of course you could crawl all you would want. Your going in circles.

Space doesn't have an end. A popular analogy: you are a bug, crawling on a balloon. You can go anywhere you want on the balloon, but have no idea that there is a third dimension. Does your space have an end? Obviously not; you can crawl as far as you please and you will never run into an end.

The nothing that existed before anything was infinitely nothing. So if space filled it, it also has to be infinite.
The movement in the universe that we can see suggests that it did have a beginning. The apparent expansion slowed for a while as if it was going to run out of gas. Then it started expanding again, apparently, and picking up speed, apparently, when all of the acknowledged forces in the universe would try to begin to draw it back together. This suggests that the movement has changed from expansion because of the beginning to inflation because of a vacuum.
Big Bang believers like to say that it has an end because it would prove the Big Bang theory, they think. We can't see the end of the universe and really have no idea what is going on. We just have theories.
A beginning doesn't mean that there has to be an end.
If it makes you feel better to believe that space ends, go ahead and believe it but, let other people believe what they want to believe.

I like the analogy of the bug on a balloon. The balloon can be expanded infinitely, but the bug will never reach the end of the balloon because a balloon has no beginning and it has no end, when inflated. A sphere has no definable end or beginning. Some theorists think that because the "Big Bang" started the universe, a big bang will end it, too. In reality, the "Big Bang" Theory offers a way to explain the beginning of how our universe was formed and how life started on Earth. It does not explain how galaxies and stars were formed, and it assumes that matter and gasses were available in space. That does not guarantee that a big bang will end our universe, although with global warming, we are well on our way to destroying Earth.

Space, interstellar space to be more exact, even in the absolute absence of matter (there are molecules of matter even in interstellar space) is not simply a void. It has some characteristics that make it something. As Einstein theorized and latter other scientists proved, space is something that can be manipulated, affected, or changed, by electrical, magnetic and gravitational fields. It can be, for example, bent by a gravitational field and, in the process make light propagate in a curve, rather than a straight line. Current theories propose that space is propagating, which is to say that the observable universe is expanding. Its limits are not presumed to be infinite. What lies outside of this space is unknown. It is assumed to be a void where even light cannot propagate since it has no medium in which to do so. When you say that everything has an end and therefore space itself should have an end too, you are not using a valid argument, though it may seem that way to you. Perhaps I can illustrate this through a simple (I think!) example. One is used to say that one plus one is two. This is not necessarily the case. Consider the case of the number of geometrical points contained in a finite length of a straight line. Their number is, of course, infinite. There are four different magnitudes of infinites known to mathematicians, but that discussion is way beyond the scope of our present discussion. Going back to the simple (¿?) infinite we were discussing, if you were to add one of those infinites with another one, you would not get two infinites of the same kind but only one of the same kind. In other words, here, one plus one is not two, but one. The point I am trying to make is that you cannot use your experience with ordinary things to extrapolate your knowledge into things that are not ordinary. The concept of space is one of them. Another example is to think about time. Did it have a beginning or did it not. If it had a beginning, and, therefore, it did not flow before its beginning, how could it reach the point at which it began? Again, the point is that you cannot use simple logic based on everyday experiences to ponder subjects that lie beyond such experiences. I hope I have expanded your understanding of our intelectual limitations to consider such concepts. Please, do not give much credence to those who claim to know that space is or is not infinite. They do not know. No one, at present, knows! Cordially,
Pavi

it cant be infinite if it has a begining(big bang) then it has to have an end or atleast an edge,.by definition the universe is all energy mass and time and ALL. but if u want to try and guess what past the edge my best guess is the epiphany of nothign a timeless void with out color space energy mas. NOTHING
i disagree with tth e ballong and bug thing because if u want to cpmpare it to that then the ballon is constanly getting bigger and the bug would have to be some were inside it cause we arent on top of the universe we are withign it so we could look out to the edge that its always getting bigger but there is still and edge and out side of it there would be like i said nothign
i think i deserve those points :P

The scientists say the universe is ever expanding.It is thought that Quasars are found at the end of the universe.As far as the border of the universe is concerned i don't think so it would ever be possible to know the end of the universe.

The universe is an infinite space. It goes in all directions. You are able to move in all three dimensions and in all directions.

God has created this big "I cant see or notice it cause I'm human" awsome teleport sitting all around the universe. Anything sent in one direction will eventually come from the opposite direction abck again to where it started! get it?

Scientists have discovered that the universe is constantly expanding. Due to this fact, there is really not a fixed point where it does end...........it just gets bigger.

A circle doesn't have an end.
