Is it possible for motion to exist at 0 Kelvin?

Movement at absolute zero refers to the movement or motion of particles at the lowest possible temperature, which is 0 Kelvin (or -273.15 degrees Celsius). At this temperature, all molecular and atomic motion stops, resulting in no movement.
It is theoretically possible to reach absolute zero, but it has never been achieved in a laboratory setting. The closest scientists have come is 0.0000001 Kelvin, achieved in 2019 by cooling a gas of sodium atoms.
At absolute zero, matter enters a state known as a Bose-Einstein condensate, where all particles lose their individual identities and behave as a single quantum entity. This state is only possible at extremely low temperatures.
The third law of thermodynamics states that it is impossible to reach absolute zero through a finite number of steps. This is because as a system approaches absolute zero, the amount of energy needed to lower the temperature decreases, making it increasingly difficult to reach absolute zero.
No, movement cannot occur at absolute zero as all molecular and atomic motion stops at this temperature. However, there may still be residual energy and movement due to quantum fluctuations, but this is considered negligible.
