Planck temperature

Planck temperature is the highest theoretically possible temperature in the universe, approximately 1.42 × 10^32 Kelvin. At this extreme level, the effects of quantum mechanics and gravity become incredibly significant, leading to unknown physical behavior. Beyond this temperature, our current understanding of physics, particularly in the realms of quantum mechanics and general relativity, breaks down. It represents a point where traditional concepts of heat and energy no longer apply, making it a critical reference in understanding the fundamental laws of the universe.
