How Small We Really Are...

Sometimes it's hard to imagine, or even have time to think about, how small we really are in comparison to this universe..

Today, I watched a movie (for free) from entitled Cosmic Voyage. Narrated by Morgan Freeman and full of neat views of both the macrocosm (big stuff) and the microcosm (little stuff), it's a real eye opener to all that's around us and where are universe came from..

It was quite humbling, especially when the film zooms out to a view like that below (from the Hubble telescope), and you realize that all of those millions of galaxies have billions of stars, which most likely have planets, and most probably life.

Take a look at all of these galaxies:

Towards the end of the film, they show two spiral galaxies colliding into one... What they don't explain is that this is what will eventually happen to our galaxy and our neighboring Andromeda galaxy (which is quite a bit bigger than ours) in about 3 billion years...

This video is from entitled How the Milky Way Will End:

If two galaxies collide, and there is no one there to hear it, does it make a sound??

Intriguing and educational.. I love films like these!
