Why is there a small lower limit to temperaure (-273.15C) but almost limitless upperbound? (million of degree in a star for example)

Question

Is there even an upper limit to temperature?

Answer 1

First of all your question has a personal bias.

The lower limit for temperature seems low to you only because you are comparing it to the habitable temperature of Earth that you are used to.

Temperatures in the millions are relatively common because stars are common.

There is an upper limit to temperature though.

If you keep increasing the temperature in a particular spot eventually because of E=MC^2 you’ll reach that limit… which results in the creation of a black hole.
