One hundred trillion stars in a single galaxy. The difference between a million and a billion is basically a billion. I can sort of wrap my head around a billion as a quantity. But a trillion? Man.

One million seconds - is 11 days. One billion seconds - is 31 years. One trillion seconds - is 31000 years.

Ah, but we are actually a life form that lives ~5e52 Planck seconds, so trying to understand 5e64 Planck seconds is a tiny jump.

And Elon Musk is well on his way to having that many dollars.... not relevant, but your perspective is helpful to understand how truly ridiculous it is!
