quantum physics
Planck-scale mechanics study
Quantum physics is the branch of physics that studies matter and energy at the smallest scales—atoms, subatomic particles, and photons.
At this level, particles behave counterintuitively: they exist in multiple states simultaneously until observed, can be entangled across distances, and exhibit both wave and particle properties.
Quantum physics challenges our everyday intuitions about reality.
Also called quantum mechanics.
