So whats beyond our universe?

Question

How far does space go and then what? What was before the Big bang?

Answer 1

There's nothing beyond the Universe. By definition. Or at least, nothing that we can acquire information about.

By the same token, there was nothing before the Big Bang. Not even time or empty space. Time began with the Big Bang. You could say that time is cyclical so that it all starts again and again and the same movie has been played and infinity of times. I guess it doesn't matter. Because all information is destroyed at the end of time, when the universe collapses. So even if we say that time will begin again, there's no way of interacting with the next generation of the Universe. So we might as well say that time only exists once.

Some cosmologist speculate about a multiverse - many universes, seperated by some higher-dimensional barrirere that we can't cross. But again, it doesn't matter. It's a construction made to explain why the laws of nature (coincidently!) are such that intelligent life could evolve - the idea being that in all the other universes, the laws are different.

Answer 2

Perhaps nothing is, and perhaps there are many universes. Some may have different laws of science. There is a limit to the Observable Universe. Red shift indicates that the Universe is expanding. Speed of recession increases with distance, and any galaxies or stars moving away from us faster than the speed of light will always be invisible to us. A book titled "The Oscillating Universe" says there may be a series of Big Bangs. The primal point explodes outward, but eventually, all matter and energy began contracting into another primal point. Then, we have another Big Bang. The "Damped Oscillating Universe' says that each Big Bang is smaller than the previous one. Eventually, there are no more Big Bangs. many variations are possible. We do not yet know enough to say what is true. Maybe time does not exist until the Big Bang occurs, so there is nothing before it. Once, the Continuous Creation theory was a rival to the Big Bang, but CC has been disproven...and BB has no logical rivals. Creation myths are not in the realm of Science and Logic.

Answer 3

In theory there was no time before the big bang, but the entire universe existed as a singularity of microscopic size that finally expanded from the heat and pressure, and over the course of about 18 billion years (current estimation of the age of the universe) it has expanded to an estimated 189 billion light years across. Most theories state there is nothing beyond the universe, some will say if an object went past the universal barrier it would simply not exist any more. Science has yet to prove this, and it will be a while before it does. We still are discovering stuff about our own solar system, and just within the last 5 years proved existence of planets outside our solar system.

Answer 4

I'm not sure anyone can answer, because science doesn't know yet. There are only hypothesis: It is said that the Big Bang created space and time (all the dimensions actually) so there was no time before the Big Bang, thus no before Big Bang. However, big Bang in itself is just a theory...

as for the space, some say it is like a 4-D sphere, if you continue on going you'll eventually go back to your starting point. There would be no "outside" the universe.

But, we may yet find all of it out someday!

Answer 5

There's another interesting theory. Originally, our universe was a very dense energy in a point, and something happened that caused big bang. One theory says that beyond our universe is another universe that might comply with different physics law. Because it is said that our universe is in 4-Dimension, (if you can imagine that if a 2D plane is bent, it becomes 3D, imagine 3D bent become 4D, it's like a sphere for 3D. You go straight in the space and you will return to the starting point) it is difficult to travel to the other universe by conventional mean (space shuttles). Until we can fully comprehend the nature of space (or dimensino), we can't find a way to travel between universe.

Answer 6

Nothing is beyond our universe.
Space goes faaaaaaaaaarrrrrrrrr.
Nothing was before the Big Bang.

Answer 7

I want to see what the experts say on this because I have always been curious about it, too. Seems like the answer is Nothingness. But how could you ever know?

Answer 8

Close your eyes and try to see what u can see...........and if you are able to see anything that's the thing which is beyond our universe

Answer 9

The universe is infinite , which means it has no boundry or edge.

Answer 10

Nothing. Forever, Nothing.
