The whole landscape of physics was changed with the discovery of Lorentz transformations, and this led to attempts to reconcile it with gravity. At the same time, experimental physicists started testing the foundations of gravity and relativity—Lorentz invariance, the gravitational deflection of light, the Eötvös experiment.
[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 ...
Approximately the first 30 years of the 20th century represent the time of the conception and evolution of the theory. The basic ideas of quantum theory were introduced in 1900 by Max Planck (1858–1947), who was awarded the Nobel Prize for Physics in 1918 for his discovery of the quantified nature of energy.
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.

The Indus Valley script remains undeciphered and there are very little surviving fragments of its writing, thus any inference about scientific discoveries in that region must be made based only on archaeological digs. The following dates are approximations. The Nippur cubit-rod, c. 2650 BCE, in the Archeological Museum of Istanbul, Turkey
4000 BC: Probable time period of the first diamond-mines in the world, in Southern India. [124] 4000 BC: Paved roads, in and around the Mesopotamian city of Ur, Iraq. [125] 4000 BC: Plumbing. The earliest pipes were made of clay, and are found at the Temple of Bel at Nippur in Babylonia. [126] [b]
Archimedes was born c. 287 BC in the seaport city of Syracuse, Sicily, at that time a self-governing colony in Magna Graecia. The date of birth is based on a statement by the Byzantine Greek scholar John Tzetzes that Archimedes lived for 75 years before his death in 212 BC. [9]
