For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

The Bohr model is a neat but quite imperfect depiction of the inner workings of an atom before things got too muddled up by quantum principles.

The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force.

A new, testable theory proposing three-dimensional time as the "primary fabric of everything" could help unify quantum ...

A new quantum theory of gravity has been developed that aligns with the standard model of particle physics, potentially enabling unification of gravity with the other fundamental forces.

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter ...

Single-atom catalysts (SACs), with their excellent metal atom utilization and unique physicochemical properties, hold promise for broad applications, especially in heterogeneous catalysis and ...

The Big Bang theory is wrong and the universe is sitting inside a black hole, scientists have suggested. Since the 1930s – when Belgian theoretical physicist Georges Lemaitre proposed the universe ...

Big bang theory is introduced 1927. Georges LeMaitre (1894-1966) ... LeMaitre put forth the idea that there was once a primordial atom which had contained all the matter in the universe.
