What is Absolute Zero

The word cold describe something that is not a quality in itself but rather an absence of something: heat.
Heat is energy, and energy drives motion. The whole universe is made up of molecules dancing with the energy of heat.
It's a raw, random motion.
The faster the molecules move, the warmer the substance they make up.
Even a jug of ice water harbors so much molecular motion that if you gently place a drop of ink on the surface, it will diffuse evenly throughout.
In theory, absolute zero is a point where all motion—and hence all heat— ceases to exist.
Quantum physics says that absence of motion is impossible.
Absolute zero is about -273 degrees Celsius (- 460 degrees Fahrenheit) .
