An impossible question to answer

The Big Bang didn't explode INTO space, it was an explosion OF space. It created existence itself, and therefore cannot have an "edge" because nothing exists outside of existence itself.

Not really. String theory says different.
 
How is it possible that it would end? What would be the "edge"?

In a way the same question the another way around.

Space is never born, it has always been there.

How is that possible?

Well, it's hard to think of things that no one can not understand or explain.
 
I've always liked Terry Pratchett's explanation of the Big Bang: In the beginning was nothing. Which exploded.
 
String theory has a multiverse. If that's the case (and it has become more and more accepted) then outside of our universe is another and another and another that go beyond our own horizon because they are infinite and our universe is not. Or something like that.

Yes. Much like M-Theory: strings are really one-dimensional slices of a two-dimensional membrane vibrating in eleven-dimensional space. Open manifold of flat space.
 
Space, deep, very deep, 360 degrees deep,
unless of course, it's only a small room and someone had turned out the light.

If you walk far enough, you'll fall off the edge of the turtle shell. It's turtles all the way down and you'll see every fucking one of them.
