It turns out that in order to answer that question, you need a little of quantum ... the history of chemistry," a 1978 paper on the topic explained. "It seems to be mainly a relativistic effect." ...

Quantum gravity (QG) and general relativity (GR) are two fundamental theories in physics that seek to explain the nature of the universe. General relativity, formulated by Albert Einstein ...

Besides quantum theory, general relativity is one of two pillars of modern physics – our working theory of gravity and of the very large, of planets, galaxies and the universe as a whole.

Finally, relativistic quantum processes can be studied in laboratory during laser-target interactions, where high-energy events like electron-positron pair productions occur in a plasma environment.

is a quantum field theory of gravity. Alone of the four forces, gravity has no particles attached to it, and is instead explained by Einstein’s general theory of relativity as the warping of ...
