Metal Civilization's use of the Absolute Zero Domain is an ultimate weapon that exploits absolute zero technology!
Generally speaking, absolute zero does not exist in the Universe.
This is because, at the microscopic level, the temperature of matter is actually particle vibration, including Electron orbiting the atomic nucleus, spinning, and so on. It can be said that vibration is one of the basic properties of particles. Scientists, when studying basic particles, consider mass, charge, and spin as the three basic properties and have even distinguished bosons from fermions based on the property of spin.
It is because of this basic property of particles that creates a paradox with absolute zero, hence absolute zero does not exist.
