The 12th-century scholar Al-Khazini suggested that the gravity an object contains varies depending on its distance from the centre of the universe (referring to the centre of the Earth). Al-Biruni and Al-Khazini studied the theory of the centre of gravity, and generalized and applied it to three-dimensional bodies.
[249] [250] LIGO-VIRGO and Fermi constrain the difference between the speed of gravity and the speed of light in vacuum to 10 −15. [251] This marks the first time electromagnetic and gravitational waves are detected from a single source, [252] [253] and give direct evidence that some (short) gamma-ray bursts are due to colliding neutron stars ...
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.

3rd century BC: Archimedes develops the field of statics, introducing notions such as the center of gravity, mechanical equilibrium, the study of levers, and hydrostatics. 3rd century BC: Eratosthenes measures the circumference of the Earth. [60] 260 BC: Aristarchus of Samos proposes a basic heliocentric model of the universe. [61]
The scientific revolution of the 17th century, especially the discovery of the law of gravity, began a process knowledge accumulation and specialization that gave rise to the field of physics. Mathematical advances of the 18th century gave rise to classical mechanics and the increased used of the experimental method lead new understanding of ...
General relativity is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915, with contributions by many others after 1915. According to general relativity, the observed gravitational attraction between masses results from the warping of space and time by those masses.
1974: The lithium-ion battery is invented by M. Stanley Whittingham, and further developed in the 1980s and 1990s by John B. Goodenough, Rachid Yazami and Akira Yoshino. It has impacted modern consumer electronics and electric vehicles. [509] 1974: The Rubik's cube is invented by Ernő Rubik which went on to be the best selling puzzle ever. [510]
