The Great Wall of Space

You know when you look up at the sky at night, and only see stars against a
backdrop of pure blackness...

....just what exactly is all of that blackness anyway?

Surely it has to be something.

I mean, I definitely get the feeling that I am looking at something when I
look up
at the blackness of space.

Maybe it is a giant wall, that surrounds the universe and holds it together
intact.

Maybe the wall is the outer limits of the explosion of the Big Bang so many
billions of years ago.

I mean really, doesn't it seem that the natural state of things should be
light, not dark?

Maybe it is a wall.

Maybe beyond that is light.

Maybe the stars are manifestations of that light.
