GENERAL KNOWLEDGE

Detailed explanation-1: -Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. That curvature is dynamical, moving as those objects move. In Einstein’s view of the world, gravity is the curvature of spacetime caused by massive objects.

Detailed explanation-2: -Essentially, Einstein thought space and time were intertwined in an infinite “fabric, ‘’ like an outstretched blanket. A massive object such as the Sun bends the spacetime blanket with its gravity, such that light no longer travels in a straight line as it passes by the Sun.

Detailed explanation-3: -According to Newton, gravity is the pulling-or in fact the attracting-force of any heavenly body towards any object to its center. But, to the contrary, Einstein once said that the four dimensions of space and time push the object downwards.

Detailed explanation-4: -He theorized that a mass can prod space plenty. It can warp it, bend it, push it, or pull it. Gravity was just a natural outcome of a mass’s existence in space (Einstein had, with his 1905 Special Theory of Relativity, added time as a fourth dimension to space, calling the result space-time.

Detailed explanation-5: -Einstein predicted that light should be bent by gravity, and Sir Arthur Eddington led an expedition to photograph the 1919 total eclipse of the sun. The photographs he took revealed stars whose light had passed near the sun, and their positions showed that the light had been bent exactly as Einstein had predicted.
