Newton falls, Einstein next?: Scientists dismiss Newton's law of gravity while studying black hole
The apple falling on Newton's head which gave us the famous gravitational law has recently been disproved by scientist researching black holes, according to international news reports. After releasing the world's first picture of a black hole, scientists have undertaken the most comprehensive test of general relativity near the aforementioned black hole.

apple falling on Newton's he which gave us famous gravitational law has recently been disproved by scientist researching black holes, according to international news reports. After releasing world's first picture of a black hole, scientists have undertaken most comprehensive test of general relativity near aforementioned black hole.
This test has ruled out Newton's law of gravity due to incapability to be applied in a black hole, as per Professor Andrea Ghez from University of California. scientist has also revealed impending disapproval of Einstein's ory of general relativity.

"Einstein’s right, at least for w. We can absolutely rule out Newton’s law of gravity. While our observations are consistent with Einstein’s ory of general relativity, his ory is definitely showing vulnerability," said Professor Ghez, in a press conference.
Detailing how Einstein's ory cant completely explain gravity inside a black hole, scientist ded:

“It cant fully explain gravity inside a black hole, and at some point, we will need to move beyond Einstein’s ory to a more comprehensive ory of gravity that explains what a black hole is.”
Studying a star S0-2 which orbits supermassive black hole at center of our galaxy, scientists have claimed that particular star is only one which makes a complete orbit in three dimensions which allow scientists to study various laws of physics standing test.
star's full orbit which takes 16 years around black hole, which weighs four million times more than Sun, allows scientists to conduct tests of general relativity, which has ultimately led to Newton's ory's downfall.

" laws of physics, including gravity, should be valid everywhere in universe," said Ghez gravely, leing one to wonder which or physicist's ory will bite dust.
What is Newton's gravitational law?
Newton's law of universal gravitation states that every particle attracts every or particle in universe with a force which is directly proportional to product of ir masses and inversely proportional to square of distance between ir centers.

equation for universal gravitation thus takes form:
F= G * (m1*m2/r^(2))

where F is gravitational force acting between two objects, m1 and m2 are masses of objects, r is distance between centers of ir masses, and G is gravitational constant.
What is Einstein's ory of general relativity?
General relativity generalizes special relativity and refines Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of and time, or time. relation is specified by Einstein field equations, a system of partial differential equations.
