This is only what we can see of the known universe.
But as a matter of fact we actually have proof that there is more beyond the known universe, and beyond that there are most probably multiverses, just
like galaxies are found in clusters, Universes are found in clusters, what is beyond that, we might never know.
The so called Big Bag was never the beginning, it was just a step in an infinite cycle of steps which the Universe, and all multiverses goes through.
Only mankind with our limited minds could conceive a beginning, and an end, but the Universe, and the multiverss are not confined by man's mind.
Just like the cycles of life, death, rebirth, life, death, rebirth, etc, in an never ending cycle so does the Universe, and the multiverses go through
similar cycles.
Anyway, without further due, here is what we have found so far from beyond the known Universe.
Mysterious New 'Dark Flow' Discovered in Space
As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered.
Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known
gravitational forces in the observable universe. Astronomers are calling the phenomenon "dark flow."
The stuff that's pulling this matter must be outside the observable universe, researchers conclude.
When scientists talk about the observable universe, they don't just mean as far out as the eye, or even the most powerful telescope, can see. In fact
there's a fundamental limit to how much of the universe we could ever observe, no matter how advanced our visual instruments. The universe is thought
to have formed about 13.7 billion years ago. So even if light started travelling toward us immediately after the Big Bang, the farthest it could ever
get is 13.7 billion light-years in distance. There may be parts of the universe that are farther away (we can't know how big the whole universe is),
but we can't see farther than light could travel over the entire age of the universe.
