Sometimes you hear something that's truly awesome, this is even more marked when the more you think about that thing, the more awesome it gets. I read this statement the other day..
If you hold a grain of sand at arm's length, the patch of sky it covers contains 10,000 galaxies. Not stars, galaxies.
Astro Physicists reckon that the average galaxy has at least 100 million stars (like our Sun) in them and each star probably has a number of planets orbiting it. That means the chances of there being "Earth-like" planets out there (i.e. in the Goldilocks zone) is remarkably high, suggesting the possibility that life is evolving someplace (other than Earth) also highly likely. The sad thing to consider though is that these planets are all so far away that it's highly unlikely Humans will ever visit them or even receive EM radiation (i.e. radio/light waves) from them before we go extinct (probably by destroying ourselves somehow). So, awesome and shocking at the same time, "shock and awe" as they say..
