Diagram regarding the confirmation of gravitomagnetism by Gravity Probe B. Gravitoelectromagnetism, abbreviated GEM, refers to a set of formal analogies between the equations for electromagnetism and relativistic gravitation; specifically: between Maxwell's field equations and an approximation, valid under certain conditions, to the Einstein field equations for general relativity.
Magnetoreception. Experiments on European robins, which are migratory, suggest their magnetic sense makes use of the quantum radical pair mechanism. Magnetoreception is a sense which allows an organism to detect the Earth's magnetic field. Animals with this sense include some arthropods, molluscs, and vertebrates (fish, amphibians, reptiles ...

Levitation (physics) Levitation (from Latin levitas, lit. 'lightness') [1] is the process by which an object is held aloft in a stable position, without mechanical support via any physical contact. Levitation is accomplished by providing an upward force that counteracts the pull of gravity (in relation to gravity on earth), plus a smaller ...

Ning Li (Chinese: 李宁, pinyin: Lǐ Níng; January 14, 1943 – July 27, 2021) was a Chinese American scientist. Born in Shandong, she graduated from the Department of Physics of Peking University, and in 1983 she emigrated with her family from China to the United States. [1] She is known for her physics and anti-gravity research.
The Cavendish experiment, performed in 1797–1798 by English scientist Henry Cavendish, was the first experiment to measure the force of gravity between masses in the laboratory [1] and the first to yield accurate values for the gravitational constant. [2] [3] [4] Because of the unit conventions then in use, the gravitational constant does not ...
e. In theoretical physics, supergravity ( supergravity theory; SUGRA for short) is a modern field theory that combines the principles of supersymmetry and general relativity; this is in contrast to non-gravitational supersymmetric theories such as the Minimal Supersymmetric Standard Model. Supergravity is the gauge theory of local supersymmetry.
