SUMMARY
Absolute zero, defined as 0 Kelvin or -273.15°C, is the lowest possible temperature. It is fundamentally unattainable due to the Heisenberg uncertainty principle, which states that certain pairs of physical properties cannot be simultaneously known to arbitrary precision. This principle imposes a limit on how precisely we can control the energy states of particles, preventing the achievement of absolute zero.
