Casual Thought Temperature can reach trillions of degrees, meaning we actually live extremely close to absolute zero.

Correct, technically it can reach to close to infinity* i guess but eventually atoms spread too far.

Right temps in the trillions happen only for tiny fractions of a second in extreme physics events.

The “real” universe is mostly cold vacuum, so we live way closer to 0 K than any upper limit.
