Does space have an ending....at all????

Question

my friends says it keeps getting bigger and bigger every second but that sounds strange if there was some way AT ALL that we could find out that'd be like so cool!

Answer 1

And who are these friends? Einstein? Hawking?

The things inside of space like "time", "distance" and "velocity" are finite and measurable. The place they live in, the domain we call "space", has no boundaries. It does not grow or shrink. We feel like it does because we are also things inside the space...

Tyler's answer is best because it is short. E=MC2, a very short equation.

Answer 2

That's an unanswerable question — in definite terms at least.

The OBSERVABLE universe is certainly finite; it's a sphere 13.7 billion years in diameter around the Earth. We cannot see further than the point after the Big Bang at which space became transparent. Since the speed of light is finite then any time we look at an object we are seeing how it appeared in the past. The further we look, the further back in time we are looking. And so the furthest we can possibly look is the distance determined by how much time has elapsed since space became transparent. This boundary is visible in radio telescopes as the cosmic background radiation image.

Now, suppose you somehow instantaneously traveled to a point 13,700,000,000 light-years away. What would you see? Well, of course no constellations you know would be visible (since they are formed by the geometry between stars close to Earth), but otherwise the view would be indistinguishable from the view from Earth; all of the laws of physics that we observe here would be in effect there, including a limit on observational distance of 13.7 billion light-years. The reason it's symmetrically placed around us is because we are observing, not because we are in a special place of symmetry with the edges of the universe.

So, since there is no way to observe the furthest reaches of the universe there is no way to say what happens at the edge of the universe, if indeed such a thing exists. I don't believe it does, because that region would exhibit drastic violations of the laws of physics, which do not appear to change *anywhere*, aside from within singularities such as black holes.

Answer 3

At this point in time there has not been any ending, top, bottom or sides ever detected or observed to the Universe.
It is vast beyond belief, extending out some 13.7 Billion Light Years to the fartherest objects we have seen from Earth.

Radio Telescopes have detected objects out as far as 40 Billion Light Years in all directions from Earth.

In all honesty, you need to sit down and try to write down
on paper the distance in "miles" represented by
40 Billion Light Years. Only then will you have some good
appreciation for the vast size of space that we can "see" with our best equipment. That is only the distance we can "see", not the end of it. Maybe in a few years someone will come up with a new advancement in optics or radio astronomy which will extend our capabilities out to 60 or 80 Billion Light Years. Only time will tell...

Answer 4

Well no one quite knows for sure because no one can ever manage to go very far in space! But we are managing to send something to pluto in 2010! But i agree that would be way cool to find out! My opinion is that space just doesnt have an ending! Good Luck!! P.S. in the future I think we'll find out! Best Wishes Natalie

Answer 5

big bang is the initial explosion that created the universe, and since space or more to say 'void' doesn't have any friction, the explosion continues till today making the space expand.

and there is a theory about the entropy of the universe that it will implode and the universe will cease to exist

Answer 6

the expansion of the universe is like that of a balloon. as we expand we get farther apart from other parts of the universe. in time (according to theory) we will be so far apart from all other stars that the earth will simply freeze. the problem is that the expansion of the universe is traveling at the speed of light. nothing can travel at this speed or it become pure energy. picture yourself running up an escalator going down at the same pace. you can run all you want but you're getting nowhere

Answer 7

No, space does not have an end. You can't fall off of the universe. And yes, it is expanding also: All of the distances between all of the galaxies are increasing.

Answer 8

Why that person above says nobody knows it.
I know it. It will keep expanding. There is no end to the space. Every human uses about 7% of their brain.
If u meditate and use about 30% of u'r brain u will be able to travel in space.
thanks

Answer 9

sorry hunni! nobody knows, and we will never find out. it is an unanswerable question. but think about it. do you think there is just a wall that stops space in the middle of nowhere. if so what would be behind the wall, even nothing is something. just forget it, maybe u will figure it out one day

Answer 10

yeah your frnds are telling you the correct thing...its got an ending but this ending is getting farther and farther away from earth....this is according to the big bang theory of collision, and it was proved that this theory is a true by an Indian scientist Chandrashekhar.
