What happens when you reach the end of the universe?

Question

I mean, do you hit a big black wall? Every thing in life that we know of has a beggining and end........

Answer 1

An answer I once got:
Imagine a multidimensional dodecahedron, where the opposite sides are connected (on the outside) (as in they touch. If you tried to fly out one, you just come back on the other side.
Many scientists think that the Universe is dodecahedron - shaped.
Forget the mobius strip, think of a sphere, it is of finite size, but no matter how far you go on its surface, you don't leave...

Answer 2

Let me ask you a different question. What happens when you reach the end of the Earth? Do you hit a big black wall or do you simply fall off? Just like the surface of the Earth has no end since it curves around itself, the universe also curves around itself in four dimensional space time. So there is no end. Go in a straight line long enough and you will end up right where you started.

Answer 3

Nothing. The universe is an endless expanse defying time and matter as we men know about them.

Yes, there is a geographical and time limits to us humans, because we are here on earth. And that's how God planned it for us.

The bible says God created the universe out of nothing - the earth, the sun, the moon, the stars (Gen 1:1). So to begin with, there is nothing in there - a dark, endless void. That is why God's creation made the whole universe a wonderful thing - from nothing to something.

Even if fwe ollowed your assumption that there has to be limit somewhere at the end, no one can reach it for three reasons:

1 It will have to be very, very far that ...
2.No one will survive the trip because life has to end for the
traveler. The bible says our life is only about 70 years, or
80 years, or thereabouts for reason of strenght (Ps 90:10).,,
and
3.No amount of fuel will last to carry anyone to the ends if they
existed.

Or imagine an astronaut falling from a spacecraft while in outer space. If he had a body that would survive the friction of the fall or the nonsustenance with food or water, he will have to fall, fall, fall forever .... ad infinitum ... ad infnitum.

Answer 4

Well they believe that it goes on forever, ant that the universe is still expanding. So that would mean there would be nothing there. But I think it is a lot more complicated, like how a circle has no end. But it is something we haven't the slightest clue about. Something we just haven't discovered yet. I think it is much more complicated than a sphere. We probably will never find out, maybe in millions of years, but not you or me anyway.

Answer 5

we live in a 3 dimensional universe. and some of u think that even though everything we see and have ever know of is 3 dimensional. and now u think that its 4 dimensional. so u reach the end, and ur teleported (yes, thats the only way it could work) to the other side. thats idiotic. i feel sorry for the man the came up with that.

Answer 6

We are at the end of the universe but we keep expanding into empty space. You can go nuts thinking of this sort of thing. Even the greatest minds have never come up with a convincing explanation.

Answer 7

It doesn't have an end. You could go as far as you please, as fast as you please, but since all locations are equivalent (relativity, you know), the universe won't look any different (except in details of specific location of stars) than it does from here and now. And this is true even though the universe is of finite size.

Answer 8

No, no wall. There's just a Starbucks, a Walmart, and a dead-end street.

Answer 9

There is no end ... even if there were an end, there would have to be something on the other side of it, right? ?

I lose sleep over this. Best just to stop thinking about it! :)

Answer 10

As far as science can currently determine, our universe has no end. It appears to be infinite in extent, and recent scientific investigations, mainly the WMAP space mission, bear this out.
