Blog #4: Statistics Behind Our Solar System

A concept that has always intrigued me is the possibility of life on Earth. It seems like every topic we cover reveals another statistical improbability that has allowed life to exist on Earth at all. For example, we are just far enough from the sun that we have an atmosphere, but not so far from the sun that our planet is completely frozen. Our atmosphere blocks out harmful rays from the sun, but traps just enough heat to keep the entire Earth warm the whole day. The earth is big enough to support a sizable human population but not so large that humans are crushed by the force of gravity. The list goes on.

This conversation also opens a can of worms for many people regarding religion and the possibility of the creator of the universe (which I obviously don’t want to get into here).

  1. Hi Jack! Thanks for your post. That is an interesting revision of the Drake Equation. Look up Jupiter’s Moon Europa to see where astronomers give a high chance of finding some other type of life in our Solar System. The possibility is based on just the right amount of tidal interaction between Jupiter and it’s moon. This is another potential case of things being “just right” against all the odds!
