The gravitational constant G is a key quantity in Newton's law of universal gravitation.. The gravitational constant is an empirical physical constant involved in the calculation of gravitational effects in Sir Isaac Newton's law of universal gravitation and in Albert Einstein's theory of general relativity.
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]
Horndeski's theory is the most general theory of gravity in four dimensions whose Lagrangian is constructed out of the metric tensor and a scalar field and leads to second order equations of motion. [ clarification needed ] The theory was first proposed by Gregory Horndeski in 1974 [ 1 ] and has found numerous applications, particularly in the ...
Designed as a medium bomber, the G.II did not share any attributes with the larger G.I, being a single bay biplane with thick section upper wings and rigid X member inter-plane struts. The graceful lines of the fuselage were spoilt by the twin nose-wheel assembly, intended to reduce damage on nose-overs and at rest with a forward centre of gravity.
ROME — Buried in ash after Mount Vesuvius’ cataclysmic eruption in A.D. 79, hundreds of papyrus scrolls have kept their secrets hidden for centuries. But archeologists have now been able to ...

The gravity anomaly, or "gravity hole", is centered southwest of Sri Lanka and Kanyakumari, the southernmost tip of mainland India, and east of the Horn of Africa.Due to weaker local gravity, the sea level in the IOGL would be up to 106 m (348 ft) lower than the global mean sea level (reference ellipsoid), if not for minor effects such as tides and currents in the Indian Ocean.
