Fact of the Day: Many Planets

The Milky Way Galaxy has an estimated 200-400 billion stars, and it's assumed that for each star that there's at least one planet. Another estimate is that about 1% of those planets are in their Goldilocks zone (i.e. not too cold, not too hot) and if that was true then there would be at least 2 billion planets suitable for some form of life.

Interesting, but who can tell for sure about all these numbers. They could be just number, maybe

This is good to hear Adam, humans tend to think they are unique.
