Some infinities are bigger than other infinities.

You don’t get to have an opinion on whether .999… is equal to 1, for instance. It is equal to 1. People smarter than us have worked hard to figure this stuff out, and we owe it to them and to the universe to respect what they’ve figured out.

It seemed like forever ago, like we've had this brief but still infinite forever. Some infinities are bigger than other infinities.

Sembrava passata un'eternità, un'eternità che sembrava breve ma allo stesso tempo infinita. Alcuni infiniti sono più grandi di altri infiniti.

Some infinities are bigger than other infinities...

We think of infinity as a really big number, but it’s not. It’s endlessness. Endlessness is a really strange idea in a universe that is defined by its endings.

I thought of how infinity is not a large number. It is something else entirely. It is boundlessness. You cannot travel faster than the speed of light. You must and will die. You cannot escape these boundaries. But the miracle and hope of human consciousness is that we can still conceive of boundlessness.
