wanna know some fun math that makes me terrified of everything
imagine taking every single atom in your body, and expanding that atom into a clone of yourself. the new total number of atoms is about the same as the total number of atoms in the planet earth.
now do it again. take every single atom in the planet earth, and expand it into a copy of the whole.
that’s roughly how many atoms are in the observable universe.
in other words
You^2^2 = Universe.

I also realized something...
If the universe really is infinite...
It will never be dark.
Even after every star has died and has been dead for trillions or quadrillions of years, there will be a faint band of light in the deep distance where you could watch the entire history of the star-filled universe playing out again and again. You'd watch light emerge, stars be born, worlds form, lives start. Even after the entire universe has been reduced to nothing more than randomly drifting particles, you'd be able to see the era of life and light from where you were.
That's a comforting thought.

At least until the expansion of the universe reaches the speed of light.
Then it would never reach you.

But it would still be there.
Inaccessible, but ever approaching.
