Answer (1) There are many theories, and as you can imagine, they are not easily tested. The above answer is generally the inevitable conclusion. But some of the theories are quite fun. Think for a minute about the surface of a globe, like the earth. If you had a super powerful UFO taxi, you could start traveling along the earth's surface, and you could just keep going, as long as you wanted. You would never ever hit any kind of wall. You could go in a straight line (as straight as you can manage on a globe) or twist and turn. You would never reach a point where you are forced to stop. (You'd go up to avoid inconventient things like mountains and skyscrapers). Now you could find yourself back where you started, and you would often cross a path that you traveled before. But nothing would stop you from moving ahead. So we can say that the surface of the globe is finite, there is only so much area on the earth, but it is unbounded. No fences or weird walls that force you to stop. Now think about space. Because of various kinds of curvature of space, some people think of space itself as being finite, there is only so much, but the amount is beyond imagining-- and it is also unbounded. You can just keep going and going. Although, if you could survive the trip, you might eventually find yourself back where you started, without ever hitting any kind of obstacle at all! Because there is no outside. No end, no outside, yet finite and unbounded. Answer (2) There may be many theories that space is infinite. But since there is a starting point , then there may be an endpoint. Someday we may find that endpoint. Answer (3) The universe goes on in infinite space and time, and we are just intelligent living organisms trying to find answers about it. Answer (4) We can travel as far as our 'horizon', which depends on our size and how long we live. Fortunately, the closer to the speed of light we travel, the longer we live in the universe's time frame. The longer we survive, (individually and as a species), the farther we can get.
Answer (5) We may never know. The universe is apparently constantly expanding. One theory is that the universe will be expanding forever. Another theory is that the universe will stop expanding, and gravity will pull the matter back into one big superdense and super hot singularity. Before the 20th century, astronomers believed the Milky Way galaxy was the entire universe and only 100,000 light years in width. But in the 1920's Edwin Hubble discovered that the farther a Galaxy is from Earth, the faster it appears to be moving. This indicated that the universe was constantly expanding. And perhaps the edge of our universe is a wormhole to a parallel dimension. The universe can be considered infinite.
As far as physics allow you to go. Endless.
A light beam can go 158E24 meters to to the end of the Universe.
"A end of the universe" are not existing! The universe is endless.
As far as modern technology has detemined there is no percievable limit to the universe, and no evidence to support the idea that there may be other universes.
One has to go to far-away galaxies to get hold antimatter particles
There is no end of the universe. The universe goes on for ever and ever.
Well, we don't actually know that the universe itself rotates at all. The only movement we've established thus far is the generalized expansion and the movement of individual structures within the universe.
There is only one Universe (as far as we know) and we are in it.
Our Solar System is extremely far from the center of the universe. Really, we don't even know what the center of the universe is, and we are not a part of it since our galaxy is traveling across the universe.
there is only 1 universe...although there is many galaxies contained in this universe.
galaxy is in the universe
The universe will expand forever, there is no limit as it still expands today
Far away and long ago (they were common early in the life of the universe).
There really is no shape of the universe. It is like air, it really has no shape. But maybe many, many light years away it reaches to the end of the universe and it has shape. But right now our technology cannot tell, or go that far.
There is no single spot that can be distinguished as the center of the Universe. To put it another way, wherever you are, it seems you are at the "center" of the Universe.
As far as I know, Lego Universe 2 isn't out yet.
The universe is everything that exists. Either in actuality OR as far as we can percieve it.
This is deduced from the expansion of the Universe. Far-away galaxies recede (go away) from us, with such a speed, that they must have been near us about 14 billion years ago.
He isn't dead in the expanded universe. DaltonBlake11: He doesn't Die in the expanded universe as far as we know
13.2 billion years. So far. We have no idea when or how the universe might end.
As far as we know - there is "no outside of the universe", so nothing.
To the end of the Universe.
As far as we know, yes.
