Brahmagupta (c. 598 – c. 668 AD) was the first Indian scholar to describe gravity as an attractive force: [38] [39] [failed verification] [40] [41] [failed verification] The earth on all its sides is the same; all people on the earth stand upright, and all heavy things fall down to the earth by a law of nature, for it is the nature of the ...
In physics, gravity (from Latin gravitas 'weight' [1]) ... In 1971, scientists discovered the first-ever black hole in the galaxy Cygnus.
[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 ...
The first relativistic theory of gravity was proposed by Henri Poincar ... However, Karl Schwarzschild discovered in 1915 and published in 1916 [27] ...
The first observation of a decrease in orbital period due to the emission of gravitational waves was made by Hulse and Taylor, using the binary pulsar PSR1913+16 they had discovered in 1974. This was the first detection of gravitational waves, albeit indirect, for which they were awarded the 1993 Nobel Prize in physics. [98]

The publication of the law has become known as the "first great unification", as it marked the unification of the previously described phenomena of gravity on Earth with known astronomical behaviors. [1] [2] [3] This is a general physical law derived from empirical observations by what Isaac Newton called inductive reasoning. [4]
