Where is the boundary of the universe?

Answer 1

Today we know that our Universe is finite but unbounded. This means that the Universe started as an infinitesimally small point and expanded exponentially to today's size (estimated to be hundreds of billions of light-years across but ony about 14 billion light-years is visible), but the Universe has no center and hence no boundaries. Every point in the Universe looks the same (we call this property - isotropic). A good analogy would be to compare the Universe to the surface of a shereical balloon. There are no center and there are no boundaries on the surface of the ballon. If you travel from one starting point and keep moving, you will eventually come back to the same point. This is true of our own Universe.

Answer 2

It is really a difficult question to answer. Because we are such small creature in the world that we can not visualise the whole world so how can we do for universe. I am not telling that there is no limit. But it need to be proved by different physical techniques. Like Hubble space station uses visible radiation cameras, Chandra X-ray observatory uses X-rays to see the objects at distance places, and Gamma ray cameras are also used, recently Infrared Camera will be in use to see a more better picture of core of a star or formation of star etc. Unless and untill it will be proved, we have to consider it as infinite. Other thing is that the universe is expanding and hence we have a spiral galaxy. So if we say some poing to be the boundary the at some instance it may be inside the galaxy and hence in universe.
Possibilities are also there that there may exist other galaxies or universe other that ours. So we have to wait till it has to be proved.

Answer 3

The boundary fo the Universe where mass still exist has be calculated as the radius = 1.42 x10^26 meters.
Howevewr the substance of space in order to hold the Universe as it is, must at least extend 3 time that calculated distance.
As per Einstein a very renoown scientist state that the Universe is finite since it curves. Therefore it must have definite restrains on that Boundary.
It is basically a very infinitessimal small dot in the realm of our Creator's Heavens.He can get rid of that "DOT" at His own volition .That depends on the turn out of the Humans on this Earth. Right now with all these suicides & UnGodly terrorism ; the Human race is not doing so good.

Answer 4

For there to be any boundary or edge to our universe there would have to be some 'thing' or some 'where' beyond. No matter what anyone tries to tell you about parallel universes, some so-called mother universe, etc., there is not one single shred of evidence that there are such things. At this time in our scientific history, our universe is all there ever was, is now, or ever will be--it has no edge or boundary.

Answer 5

Astronomers, using the hubble space telescope, were able to detect the most distant galaxy in the far end of our universe. I think they have somehow able to estimate the actual size of the universe based on its age. You see, boundary its not the problem because they could tell where it is (the farthest galaxy). The problem is, if there's another universe beyond ours. Many scientist believes that multiverse do exist. Imagine our universe is just like another star in a galaxy filled with countless universes.
Now, that's really something to think about. I really hate the word infinity because for me, it's like there's no meaning for everything.
It's like a chicken and egg question. Who created who. If god created the universe then who created him and then who created who created him and so on and so forth. As if there's no end. I myself really want to know the boundary but not the universe, the boundary of everything, the very extreme of everything. From the very tiniest to the very largest object.

Answer 6

First we need to define what we mean by universe. Are we talking about the space or the object contained therein.
It is assumed that the questioner is meaning space. A theory of time space continum was propounded when the scientists were trying to undersatand the origin of universe. Some propounded that space grew when time ceased to stand still and is expanding infinitely ie., as long as time exists the space will continue to exist and as long as time is changing so will the space.

Now the question when time came into existence is another subject for debate :D

Answer 7

The universes is a constantly expanding thing without fixed boundaries, that's what Hubble proved.

Answer 8

Models of the universe generally assume it looks the same everywhere and in every direction (homogeneous and isotropic). Things would look different near a wall (hey, Joe, there are no stars over there). So, finite volume or otherwise, space is unbounded. The peculiar nonintuitive nature of Dr. E's noneuclidian curved space-time allows for such things. Balloon analogies are helpful, but you need to get past 2-D to grok it.

Answer 9

There is no such thing as a boundary to the universe

Answer 10

It doesn't have one. A popular analogy is to a bug crawling on the surface of a balloon, unable to sense anything except the balloon's surface. The bug will never encounter a boundary, even though the balloon is of finite size.
