A Nother Planet

"In the piece of the universe we can see there are something like 2 trillion galaxies. And each galaxy, let's say, is around the size of the Milky Way. The Milky Way has 400 billion stars in it. It takes light over 100,000 years to cross a galaxy, and there are 2 trillion of them in a piece of the universe we can see. And that piece we can see is a small bit of what may be an infinite universe beyond." - Brian Cox (English Physicist)
