Is there a hottest possible temperature?
A laboratory temperature record and a theoretical temperature limit answer different questions. Extremely hot matter created in particle collisions is measurable indirectly; the Planck temperature points toward a regime where the usual description of physics becomes uncertain.

The physicist’s explanation separates a speed limit from an energy limit and treats the Planck scale as a question about the theory’s reach.
