what is at the end of space if there is an end?

Answer 1

Space doesn't have a beginning and an end. It's what fills the gaps between everything else. That everyhing else makes up the universe which is finite but also doesn't have an end.

Answer 2

If you believe in the big bang theory the universe is like the shell of a Smartie or an M n' M, a very big Smartie or M n' M shell. The chocolate is the bit it expands out of and the area around the shell doesn't exist so it doesn't matter.
Now due to the expansion of the universe, (apparently it's still expanding) and the rate it expands, you'll never reach the edge of the universe anyway. Also due to the curvature of space if you were to fly in a straight line you would eventually end up back where you started off. It'd take ages but it'd happen, providing you avoid all the dangers in space.

Anyhow in answer to you question. I would like to think whoever was responsible for making the universe would be there and he or she would have a lot of things to answer for.

Answer 3

I am confused...Every night there are five or six questions in here about what is the end of the Universe or where is the edge of space...What is the fascination about this question that makes it come up so often? Why don't people search on yahoo answers to see if the question has been answered before.

I will answer it one more time...

The Universe consists of a vast amount of empty space with various objects moving within it. With all of our sophisticated optical and radio telescope equipment we have been able to see objects out to distances of 40 Billion Light Years in every direction. You cannot measure distances from here to an empty point in space. However, with the equipment that we now possess, we have been able to measure distances out to objects that are 40 Billion Light Years away from us. Beyond that distance our equipment fails to provide us with any useable information...limitation of the equipment we now have...Maybe in the not to distant future a new technology will be developed which will permit observations out to say distances of 60 Billion Light Years or so. That would be nice...

No one has ever actually been out there that far.
No one is going out there that far any time soon.
And, if they were to try and make the trip we would all be long
dead before they even got a little part of the way out there.
An EMail Message via radio from the ship would take 40 Billion years to reach them, and 40 billion years to come back to us...And the Sun is supposed to self destruct within 5 Billion years as it uses up all of its available Hydrogen gas supply. So the Earth would not even be here with live human life when the messages were received.

So it is safe to say that the Universe (or Space, if you will) is larger than you ever imagined, and there is no end to it that is known.

Answer 4

Einstein is credited with saying something like "The only thing more confounding than infinite space is finite space." By that he was saying "What's on the other side if space is finite?"

Contrary to some answers, prevailing WAG says that our known universe is almost flat. This is based on relative mass densities of what our universe actually contains versus what it would take to be absolutely flat according to mathematics. As best as they can guess now, that relative density is almost, but not quite, 1.000 Thus, the university almost has just enough density to be flat.

There is equivalent means for looking at this. It's based on critical mass density, not relative mass density. If critical mass density is zero, the universe will be flat because it lacks the gravitational forces to bend it. The relative density 1.000 is equivalent to the critical mass density 0.000 [See source.]

Now, let's look a the universe...the whole universe, not just the known universe we can see. What we know is that we can see about 15 billion light years to the horizon or rim of our known universe. But, due to speed of light limitation, we can see no further. So we have no way of knowing what lies beyond the 15 billion light year radius measured from Earth.

Here is one WAG. Picture the entire universe as a blown up balloon that has tiny tiny white dots painted on its skin. The dots are galaxies, you know billions of stars clustered together. Pick one dot and call it the Milky Way. Draw a 15 inch circle around the Milky Way dot. The area inside that circle is our known universe, the part we can see.

The rest of the balloon's skin, outside the circle, is the unknown universe...the part we cannot see or measure. At a minimum, the area of the skin of that balloon outside the circle of known universe is three times the area of the known universe. It could be much more, but there is at least three times more unknown universe than known universe. And that's only if the known and unknown universes exist solely on the skin of that very large balloon.

What about the volume of that balloon...inside the skin? That is really unknown universe, if it exists at all. My WAG, which is just as good as anybody's, is that the big bang went off in the middle of the balloon, the center of a spherical total universe, and our known universe exists on the skin, outer part of that big bang balloon.

But then, what's the BBB expanding into? And where did the energy come from to create the BBB in the first place?

String/M theory has a SWAG, which is a silly WAG...there are parallel universes existing in higher dimensions...like slices of bread in a mega loaf universe. Two of these slices collided, which can account for the BB energy.

As I said, a SWAG, but at least its something.

Answer 5

The current theory of space is that it is a 3D surface of a 4D hypersphere, which is hard to swallow for most people. But it is just like a 3D sphere have 2D surface. The 2D surface will be finite but have no boundary in normal sense.
Our space is like this but in higher dimension.
That dont mean that space have no end. There are boundary of universes called a black hole. A black hole make the space-time curvature to become infinite due to its gravity well. As the curvature of space time become infinite the preditability of physic and math break down. As a universe is defined as a region where the same law of physic and math apply, the region beyond the black hole is considered another universe. So black hole is the end of space.

Answer 6

Until we have better skills at comprehension, I'm settling for there being a "Power" (God, if you like?), beyond the Universe(s) and I'm not a creationist!!

Edit :
'zahbudar'. Your info is excellent (3 below this), but how can you and your ilk, simply IMAGINE infinity? It isn't humanly possible, nor is imagining 'nothingness'. There HAS to be something out there - Perhaps we will only discover what it is when we die?

Answer 7

there is a theory that although space may be finite, it still has no end. think of the earth. it has a finite area but no end, and some hold that space itself may be curved in on itself in the same way

Answer 8

Space has to be endless. Because if it had an end there would be something after that. And so on. and on...

Answer 9

By Space, I presume you mean the Universe, which is infinite.

The Big Bang theory is largely discredited.

Answer 10

I think a better question would be, what's at the end of the universe.
