What's on the other side of the universe?

Answer 1

There is no "other side" to the Universe by normal definitions. The Universe is a self contained object which may, or may not have a geometry that is close to flat in 4D space (3 normal dimensions + 1 of time). However, in higher dimensional space, the Universe is nothing more than a surface upon an (at least) 11 dimensional object. The "other side", by that definition, would be the space of the other, higher dimensions......which would be, in fact, infinitely larger than the Universe that we see.

However, if you talk about the "Observable Universe".....that's a nearly flat geometrical surface about 30 billion light years across. The whole Universe is a different matter entirely. Due to inflation in the earliest stages of the Universe, during the Big Bang, space itself expanded outwards many times faster than the speed of light. The whole Universe (or megaverse if you like) could be trillions of trillions of light years wide. That would account for the flatness of what you see as the observable Universe.

A good analogy of this is the horizon distance that you can see on Earth (which is about 10 miles). You're essentially viewing a flat surface out to the horizon. You cannot see the Earth's curvature because the curvature of the Earths surface is only visible at heights above its surface. You can see the effects of curvature if you watch a ship disappear over the horizon, but the horizon distance is still the maximum distance (at sea level) upon which you can see the surface as being flat.

Answer 2

Infinity! It is the beginning of time since the universe is still expanding. It started at a beginning point and is still expanding in the vastness of infinite space. There are probably endless universes that are parallel to the one we are aware of. Other dimensions that are in a different time, perhaps exist nearby. Space and time bend.

Answer 3

that is an interesting question...but why worry about the other side of the universe when we really no nothing about this side?

Answer 4

Their are several theories about existence of another universe on other side of ours. one of the theory hypothesise existence of antiuniverse according to antiparticle theory.
The most popular time-space theory predicts existence of several parallel universe at different time scale.

Answer 5

God!

Isaiah 40: 21 Do you not know?
Have you not heard?
Has it not been told you from the beginning?
Have you not understood since the earth was founded?

22 He sits enthroned above the circle of the earth,
and its people are like grasshoppers.
He stretches out the heavens like a canopy,
and spreads them out like a tent to live in.

23 He brings princes to naught
and reduces the rulers of this world to nothing.

24 No sooner are they planted,
no sooner are they sown,
no sooner do they take root in the ground,
than he blows on them and they wither,
and a whirlwind sweeps them away like chaff.

25 "To whom will you compare me?
Or who is my equal?" says the Holy One.

26 Lift your eyes and look to the heavens:
Who created all these?
He who brings out the starry host one by one,
and calls them each by name.
Because of his great power and mighty strength,
not one of them is missing.

Answer 6

If you can find one side we will look for the other side.

Answer 7

I don't think anyone can really answer that, and I highly doubt we'll ever known. We haven't even go the technology to get out of our own galaxy, let alone our own solar system.

Answer 8

universe has no sides...but far away somewhere probably some kind of lifeforms

Answer 9

A restaurant.

Answer 10

That is where E.T. lives
