Absolute zero

Absolute zero is the lowest temperature in the universe. At this temperature, atoms all act simultaneously and energy is at its lowest form. It is impossible to reach temperatures that are at absolute zero through thermodynamic means. Thermodynamics involves the use of energy, particularly heat energy which contradicts a state where energy is at its lowest temperature. This is the complete opposite of Absolute hot which is the highest obtainable heat in the universe.

Places in the Universe
Most places in the universe that are not near the blazing heat of a star or any celestial body that is capable of creating heat are probably near temperatures that are Absolute zero or at Absolute zero. In voids (which are the darkest places in the universe), light barely shines, it is at a temperature of Absolute zero.
