Question

At the very end of all universes and galaxies is ther just a big drop off of nothing or does just keep going?

Answer 1

bottemline....no one knows.  that is one of science's biggest debates. everyone has their own opinion. my personal opinion is that it goes on forever.

Answer 2

there are lots of galaxies and universes with the technology we have today it is in possible to tell.But i wouldn't say there is a big drop it would most likely keep going.

Answer 3

I suppose if it's still expanding you couldn't actually get to the edge but if you could I suspect it would be round and you would walk (or float) along it.

Answer 4

it is unknown for anyone to know it than it wouldnt be the unknown

Answer 5

You probably think of space as flat, but imagine it being a circle just like earth.(A VERY BIG CIRCLE) it goes around and around, so if you start at one end you can keep going and end up in the same place. Our spaceship will run out of fuel though when they try.

Answer 6

Since this Q is opinion, I believe as one moves away and galaxies become dots, the observable universe becomes a dot. If one keeps going, other dots become visible and condense into the shape of a leg. On that leg reads, "King of Kings. Lord of Lords."

Answer 7

At the end of all galaxies and universes, there is a big impenetrable wall made of a space metallic alloy that can withstand any force or temperature.

Answer 8

Well there is a "dark ages" before the stars ignited--

Answer 9

as far as we know, it just keeps on going.

one might consider the "edge of the galaxy" a moving thing.

it's as far as light has gone since the big bang.

since it keeps moving, and, as far as we know, hasn't run into anything, we've no reason to think that "space" does anything other than just keep on going.

note, i didn't say that it did, only that we've no reason to think otherwise.

Answer 10

The answer to this question is speculative at the moment but current thought in physics is that the universe has the shape of something called a 3-sphere, which is hard to imagine without an analogy.

A 2-sphere, for comparison, would be like the outside surface of a balloon -- the INSIDE of the balloon isn't considered at all, you have to imagine that only the SURFACE of the balloon exists. If you imagine dots drawn on the balloon and consider those to be galaxies, that is what it's thought the universe is like at this time -- as the balloon expands, the dots (galaxies) move further and further apart, and there is no "center" or "edge" of this shape.

Also note that travelling far enough in one direction will bring you back to your original position. However, the surface of a balloon is only two dimensional whereas the universe is at least three dimensional, so the curvature is in a direction we can't observe.

This sounds strange, but if you think about it, if a dot on a balloon (on a 2-sphere) could think it ALSO couldn't see the third dimension through which its universe curved through, so the idea of our universe curving in an unseen dimension isn't so outlandish after all, and in fact this concept is exactly what we work with when we consider that in relativistic physics we interpret "gravity" as mass distorting the geometry of space in an unseen dimension.

Clearly this is a difficult question to answer fully in a Yahoo Answers format, so feel free to email me for further information -- and keep in mind that this question is currently not completely answerable with the limited data we have at this time.

One of the Best Questions i've seen on here, but honestly i dont know the answer
