So today in my Physics class we watched a film called Cosmic Journey which is essentially a documentary narrated by none other than Morgan Freeman about life's journey through the creation of the universe.

One portion of the movie showed what happens when two galaxies suck each other in with their gravity and it looks like the universes biggest cosmic dance with billions among billions of solar dance partners. It really got me thinking about just the pure number of galaxies, suns, systems, and planets there are out there, as well as life existing out there.

I find it either odd or sad or perhaps a combination of the two when someone says they don't believe there is other life in the universe. Perhaps they just don't understand the scale of things, but even if life on a planet is a one in a billion chance, due to probability alone there's still a 99.9% chance that there is another planet with life on it. Just the sheer number of planets, suns, and galaxies almost guarantees that elsewhere there is a place where life can be created a flourish.

It really is the ultimate in pessimism to say that we are alone.
