is space realy infinate?

Question

Where does space and all the galaxys end and what is on the other side.
I know we would never get there in any life time but is space part of something bigger or are we all and everthing in a bubble

Answer 1

The universe is finite. Take the expansion velocity associated with the big bang (measurable) and the amount of time the universe has been around (also measurable). Put them together and you get a finite though very large size.

In a sense the universe is our bubble and we can't know (measure) what's outside it. The fact that your mind can imagine something beyond it means the real area for unlimited exploration is closer to home.

Answer 2

In fact it could be infinite or just unlimited, which is different.
We can reasonably assume that the amount of matter scattered by the Big Bang originating our universe was huge, but not infinite. Because of the explosion the matter was scattered in every direction, away from the Big Bang origin, forming an expanding globe.
Just imagine the universe as the surface of such a globe or bubble which keeps expanding. It would not be infinite but you can travel in any direction and never find an end. Just as when traveling around the Earth, and eventually returning where you started.
The expansion of the bubble increases the distances between all the galaxies on its surface. That is why the expansion is noticed in all directions.
You cannot see across the globe simply because the light also travels along the curvature of the surface, as the good old Einstein figured out.
Nobody has started a trip to find the end of the universe (too bad, as you would find a nice restaurant there!) or eventually return to the same spot.
But this is only a theory. Just one of the possible models to help our mind figure out what is happening.

Answer 3

of direction no person particularly is familiar with those products. the classic Brahmans (a pre-Hindu faith) in India had an exciting thought that corresponds to the enormous Bang. The "Breath of Brahma" is what they stated as the expansions and contractions of the universe, which ensue in cycles of billions of years. The universe starts off as a small, compacted clump of count. some "enormous bang" happens which reasons the undertaking to blow up outward, it is the exhalation of Brahma. quicker or later, the contraction reaches a snapping element, as a rubber band might, and the undertaking starts off to settlement and return to its source, it is the inhalation of Brahma. it is going to particularly returns to the small clump of count, and then all of it starts over. apparently, some physicists have all started to locate that it is actual occurring--the universe is increasing, however the cost of increasing is slowing, so as that finally the boost will end and opposite itself. of direction it is all thought at the instant. And if that's what the universe does, do no longer question me how the hell the Brahmans figured that out see you later in the past...

Answer 4

All we know is that the universe os ever expanding.... who knows if we will run out of room...come to think of it thats a human notion and everyone knows the universe is definately not human like. It might just go on forever.

Answer 5

Yes, it's infinate, but I think the human brain is too limited to understand what is the eternity

Answer 6

it isn't infinate. it is infinite. not only is it infinite but it's getting more infinite. as the matter and energy in the universe continue to expand the universe gets bigger. further if brane theory is correct our universe is one of many.

Answer 7

No sure answers. This is indeed the biggest puzzle humans have never been able to answer with any degree of confidence.

Answer 8

No one really knows.

Answer 9

yup
