Quantum Physics
Quantum Foam
Quantum foam, also known as spacetime foam, is a theoretical concept in quantum mechanics, conceived by John Archibald Wheeler. It describes the fabric of spacetime at the subatomic, Planck scale as a turbulent, fluctuating medium where virtual particles and microscopic black holes are constantly created and destroyed, giving spacetime a "foamy" texture.
Quantum mechanics
Quantum mechanics is the branch of physics that describes nature at atomic and subatomic scales using probabilistic laws and wave–particle duality. Developed in the early 20th century by figures including Max Planck, Albert Einstein, Werner Heisenberg, Erwin Schrödinger, and Niels Bohr, it provides the framework for modern atomic, molecular, condensed-matter, and particle physics, and underpins technologies from semiconductors and lasers to MRI and quantum information science.
