THAT was amazing.
I got lost.
I've been gone for like, well, for awhile.

AMAZING

As much as I enjoy this,it must get posted up on here once a week!

I have seen it hundreds of times....boring.Also the quantum slit one has been done to death.

That was fantastic graphics!

I don't know why they bother putting an estimated size for the universe. If we ever can detect an outer limit it will be a matter of time (if we survive long enough) to find space outside the universe...

Even in the same space (limited as it is), there are other dimensions and other networks of reality and limitless scope for life.

Kinda makes you realize how insignificant we really are. Thanx for starting this thread because I never would have seen this otherwise.
