Is there an absolute maximum temperature?

As I understand it, absolute zero, 0 K, is the point at which all molecular movement ceases.  A point that can only be reached in theory.

If heat is a measure or cause of molecular movement, is there a temperature where molecular movement would reach the unbreakable speed of light?

The speed of light is an upper limit for the speed of a massive object, but there is no upper bound on the kinetic energy of an object.

*The temperature is a measure of the average kinetic energy of particles in a sample*. Since kinetic energy does not have an upper limit, temperature does not have an absolute maximum.

Now, let's look at the limitations of our current understanding.

Current cosmological models postulate that the highest possible temperature is the **Planck temperature** , which has the value 1.416785 × 10^32 kelvin. The Planck temperature is assumed to be the highest temperature in conventional physics because conventional physics breaks down at that temperature.
