Space.. a little food for thought.

I never look up at the stars and wonder, what's up there? But I have been plagued with a thought that I cannot escape. Is space finite or infinite? If it is finite, then how is that possible? Is there a barrier that just says life will not exist beyond this wall? Or is space this infinite beast that flows on for longer than we can ever conceive. We are but one tiny planet, one speck on the face of the universe. Do me a favor, before you go to bed tonight just look up at the sky and ponder this thought for a minimum of sixty seconds, if you feel nothing then stop but if you are like me and feel a drive and a passion to know the unknown then sit there for a while and just think, you won't regret it.
