A Journey To The End Of The Universe
This guy explains in a very simple way, how big the universe really is. He presents in a fact driven way, why humans traveling to the stars is, in many ways, may simply be out of our reach, forever.
No matter how you see it, his presentation is pretty fascinating.
To top it off, his voice isn't like fingernails on a chalk board.
Give it a look, what do you think? Will it ultimately be possible to visit the stars in a human lifetime?
No politics please.

As a whole presentation, he presents the mind bobbling vastness of the universe perfectly.
Well, I tried....
