What's beyond our universe?

Question

Imagine humans 10 million years from now, technology is so advanced that we can go 100 million times speed of light... ok, what is you keep going straight line till the end. What would you see, would you be able to keep going or is there some sort of a force field keeping the universe together??

Answer 1

I had a theory a while back.

The universe is black because all the light has been sucked out by a GIGANTIC black hole. so if you get far enough from this gigantic black hole...White...all you see is white light.... :)

Answer 2

Try to imagine the universe as a balloon (I know someone already used this example, but bear with me).

It (the balloon) starts off as a shriveled piece of rubber and when filled with air, it expands into what you may recognize as a balloon.

Now imagine the universe like that, only this time, the entire universe is all in that thin layer of rubber. This explains why everything (galaxies, stars, planets) is moving away from each other.

What you're asking is what is beyond that rubber. We know that, in a balloon's case, it's air. The universe is far more different in this. Is there an up and down? Or is it far more complicated with a whole new dimension (as in 2D or 3D) in play that makes it so that there isn't an up or down and it is impossible to 'leave' the universe.

Another thing to question is what about the proverbial air inside? This 'balloon' theory allows us to explain the theory of worm-holes, 'shortcuts' through the universe that will take us to another part of it. If you cannot imagine this, try to imagine small tunnels inside a balloon. Also black holes could be explained in this way that they are so dense and 'heavy' that they 'sink' into the universe (like pushing your finger into a balloon, it doesn't go through, but rather sinks in).

In any case, everything that I'm talking is the compact or spherical universe theory. The answer to your question doesn't exist yet but it is very interesting to think about. Hopefully this will make it easier for those of you who have a hard time doing so.

Answer 3

There are 3 basic topologies for the universe: open, flat and closed. The first two are infinite, so you need never find an end no matter how far you travel. A closed universe would eventually bring you back to square 1. Currently, there does not seem to be enough mass/energy for a closed universe.

On the other hand, if traveling at speeds faster than light sends you backwards in time, you will eventually bump your head on the big bang. Ouch.

Answer 4

Current belief is that the universe is never ending, and curved. So if you were to travel in a straight line at 100 million times the speed of light, eventually you would end up back where you started. the curvature of space is somewhat like the curvature of the earth in that while it looks like you might be going in a straight line, eventually your path curves around and you end up where you started. however recent observations of microwave background radiation have lessened the likelihood of a curved space, and are leaning towards a model that leans toward the universe being neverending, or so large as to make no difference. ultimately though the answer remains a mystery still.

Answer 5

There will be no human's on this planet in 10 million years ! It's just a matter of time before we destroy oueselves. And we will never go "100 million times" the speed of light. NEVER. Chances are we will never even come close to even half the speed of light. Ever heard of E=mc'2 ? Google it. BTW,it should be "the universe", not our.

Answer 6

Well that is one thing that we as humans just do not know. We may never be able to travel to far away galaxies and such so to make it to the "end" of the universe is probably never going to happen. But we can all imagine what could be out there. Scientists say the universe is endless, a pretty hard thing to comprehend for the human mind, so if you believe what they say, then there is no end, no forcefield or anything holding the universe together except itself. I can't understand it myself, the concept of forever, but it's a fascinating subject to debate nonetheless.

Answer 7

No.......all the equations seem to suggest that there is no end, but it is however 'bounded'.

Think of the Universe as akin to a giant balloon. There is no end to it, but it certainly has boundaries.

The answer to your question would seem to be (according to relativity) 'If you keep on going ina a straight line, you will end up at the earth, but from the opposite direction'

Just like the diameter of a sphere meets up with itself when continued 'in a straight line'

Answer 8

We would be dead in 10 million years and so would our future families because the hydrogen and helium in the Sun will run out and explode in 5 million years. Which causeses a black hole and sucks up Earth.

Answer 9

Your imagination has taken a leap so far into the future that none of us can postulate what might be seen then.

Most likely we will see the desolation of a sandstone sphere with no water and no greenery which will follow after the destruction of earth as we know it when Hillary Clinton wins the Presidential Election in the USA in November of 2008.

Answer 10

This will never happen
End of Universe is after less than 1000 years
And Human will never reach speed of light or go outside the Galaxy

The Universe shape is like a balloon and expanding
Outside it is God's Thrown, (We can not imagine that, it is beyond our minds)

We are in this universe to worship God and do right or wrong,
God reward or punish us on our deeds after that.
That is the most important thing that we must think about.

Answer 11

I LIKE TO THINK OF THE UNIVERSE AS SOMETHING LIKE A LOOP SO THAT IF YOU GO FAR ENOUGH YOU JUST END UP BACK WERE US STARTED ALSO YOU SHOULD READ UP ON STRING THEORY STATING THAT THE ARE AN INFINITE NUMBER OF UNIVERSES OR PARALELL UNIVERSES AND THE WAY OUR UNIVERSE WAS FORMED WAS WHEN TWO PREEXISTING UNIVERSES COLLIDED CAUSING WHAT WE NOW KNOW OF AS THE BIG BANG
