Does the UNIVERSE have a boundary or OUTER LIMIT?
Do you think that our Universe has a boundary?
What would you expect to see if you were to reach this boundary?

General Relativity forbids the existence of a boundary. Fly off in your spaceship, and you will merely keep passing galaxy after galaxy and never get to the end. If the universe is finite, you will eventually return to the Earth.

The Universe has a boundary in time---the instant of the Big Bang. Looking at distant objects is like looking back in time, and if you look far enough, you'll see the Big Bang. (In fact, the furthest we can see in actuality is the Cosmic Microwave Background, which was a short time after the Big Bang.) This is our event horizion, and we can't see beyond it, although it is moving further out every day.
If you were able to travel instantly to our event horizion (through a wormhole, e.g.) things there would look much like they do here: galaxies, clusters of galaxies, all 13.7 billion years old. And our Milky Way galaxy would just be a little, distant, bright spot in the cosmic microwave background.
The universe as a whole is certainly much, much larger than our event horizon. We don't know how large---it may be infinite.

The old professor says...mass causes gravity. Gravity warps the "fabric" of space, so the curvature of space due to the mass of the universe merely causes you to continuously re-enter the U. If you went to the "edge" of the U. and looked out, what you would be actually doing is looking back into the U. as the light follows the curvature of space. So, like the Klein jar (sp?) it turns back into itself. When you try to escape the U. you just re-enter it. "Stop the world! I want to get off!" It just can't be done.

Absolutely not. God is infinite. He is without any boundaries whatsoever. He is not limited by time or space. He is the alpha and the omega.
He is the one who created us.
Isaiah 45:18
Have faith dear friends in God.

Your boundary is your individual 'event horizon`.
It may change with your velocity, but you can
never reach it.
It's just the way things are put together.

No boundary. The Universe is an inverted torus that has no end.

well sweetie , absolutely not. God is infinite. He is without any boundaries whatsoever. He is not limited by time or space. He is the alpha and the omega.
He is the one who created us. God bless

1) Nobody knows
2) I don't know enough to decide, but both sides of the argument are very interesting.
3) Millways, the restaurant at the end of the universe!!! :D

No...God created it so that we can never find out what is beyond. If we knew, there is no point of life exixsting. If we knew everything... What is the point of finding answers.
