If you travelled at 186 thousand miles a second, it would take about 13.7 billion years, to traverse 1/2 of the observable universe.

The volume of the universe, given that it would be a perfect sphere, is 128 trillion trillion metres cubed, or 80 billion trillion miles cubed, I admit the brain is impressive, but that takes the piss, being as its the reason for all existance

Ahh well, whats on the tele?:dance:
