100 million years

I like to think about time, especially how short-sighted we are.

It took “only” 100 or so million years to create life on earth (from Lex Fridman vs Andrej Karpathy @13:26).

Reading about How fast is gravity, the Neutron Star collision that enabled us to detect the speed of graviational waves a few years ago was 130 million light years away.

So in the time that the light got to our earth, earth had formed and create life.
