Why can’t we go below absolute zero?

Definition of Absolute Zero Absolute zero is defined as the lowest possible temperature, symbolized as 0 Kelvin (K) or equivalently -273.15 degrees Celsius (°C). At this theoretical limit, the classical motion of particles ceases entirely, representing a fundamental boundary in thermodynamics and quantum physics. This temperature marks a critical point where the kinetic energy of […]
