👉 Deadlight is a term used in physics and engineering to describe a situation where a system's internal energy or kinetic energy is so high that it becomes unmanageable due to its extreme levels of energy. In other words, the system has reached a state where the total energy of all its particles is equal to their kinetic energy. Deadlight is often associated with the transition from a low-energy state like an ideal gas into a high-energy state like a blackbody. It can be caused by various factors
