What are the odds?
December 5, 2013
From what we know of planetary science, the life of stars, and evolution, I calculate - ROUGHLY - that human civilization comprises about 0.000125 of the age of our planet. Maybe we can last longer, but there are no guarantees. So, finding like creatures would be a WILD stroke of luck! More likely we will find a world with lichen on its rocks, or prehistoric algae floating in the seas. We'll hope we won't find a radioactive wasteland....
An asteroid or comet headed for Earth is the only large-scale natural disaster we can prevent. Working together to fund our Shoemaker NEO Grants for astronomers, we can help save the world.
