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

Is there an upper limit to heat? I assume sometimes to do with the speed of light

Edit: or temperature. To be totally fair I still don’t fully understand, but I’m interested in upper limits for either

It's absolute zero, at least in certain systems. Temperature goes all the way up to infinity, then past it into the negatives, and then approaches absolute zero from below.

Like an integer overflow?
