The Scale of the Universe.

[Eisenhorn]

Here's a thought for you, when you look up at the nights sky, and see all those stars, you are seeing history, you are seeing life and death, the window into the past.
Now light takes millions of years to reach us, so logically what we could see might not be there anymore, it might have faded away, our ancestors might not have seen it, to the naked eye we are gazing upon the history of life.

Make of that what you will, its a thought I like to have whilst smoking a cigar and watching the nights sky.
