Empty space Quote by Henning Genz
““As we showed in figure 5, water molecules oscillate about their rest positions in ice. Quantum mechanics says that this remains true at absolute zero and will not admit a molecule at full rest. Similarly, we saw that what we call empty space is replete with the appearance and disappearance of virtual particles. Add energy, and these particles can become real. Add energy to ice, and it will melt. Moving in the opposite direction, remove energy from water and it will freeze because the water molecules attract each other; ice lets them approach as close as possible. The resulting crystalline structure is destroyed by thermal motion of the molecules when energy is added. Moving at random, the molecules emerge as individual particles, much as an electron-positron pair emerges from the vacuum when we add energy.””

Quantum fluctuations persist even at absolute zero, preventing particles from being completely at rest, and energy input can transform virtual particles into real ones, analogous to melting ice.
In simple terms: Even at zero temperature, particles never fully stop; adding energy creates real particles.
Energy changes states; add energy to see change.
