Answer 2

Einstein's idea about gravity is simple; there are 4 basic forces in the universe which make it function and they are the:1.Electromagnetism (micheal faraday made by combining electricity and magnetism)
2.Gravitation(Newton by natural observations)
3.strong,4.weaknuclear forces (by a team of physicsts in the activity of acclerators)
These were all right for einstein but some thing is wrong in the gravity, So according to the theory as soon as the sun dies the earth goes an tangential way and drifts of its path but the problem is the gravity and light reach at the same time which shouldn't happen of course because in the STR its stated that only photons(light )is the fastest in the unverse but how can light and gravity reach the earth at the same time so einstein genarlised the space-time fabric well its a fabric of space an dtime binded together i.e. the space and time are realative to each other (and now there's another problem classical mechanics and newtonian transformations don't qulify with itbut however after a brief time its proved space and time are relative to each other) now it was all alright the sun on the fabric makes a deep groove so the earth falls towards the sun but due to polar vectorial forces it tends to rotate about the orbit which is satisfied forall planets, Now the question what if the sun dies,
Hmmm........ yes this time the earth drifts after the light has reached the earth because when the sun dies the waves are formed in the fabric called the gravity waves and are carried by the gravitons they are mass less particles and of course gravity waves are slower than light. SO now the theory is corrected and exisistances of the fabric and the gravitons are proved now.

definitons: 1. gravitons:-In physics, the graviton is a hypothetical elementary particle that mediates the force of gravity in the framework of quantum field theory. If it exists, the graviton must be massless (because the gravitational force has unlimited range) and must have a spin of 2 (because gravity is a second-rank tensor field).

Gravitons are postulated because of the great success of the quantum field theory (in particular, the Standard Model) at modeling the behavior of all other forces of nature with similar particles: electromagnetism with the photon, the strong interaction with the gluons, and the weak interaction with the W and Z bosons.
2)space-time:-In physics, spacetime is a mathematical model that combines three-dimensional space and one-dimensional time into a single construct called the space-time continuum, in which time plays the role of the 4th dimension. According to Euclidean space perception, our universe has three dimensions of space, and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a good deal of physical theory, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.

Answer 3

In 1905 Albert Einstein published his famous paper on the special theory of relativity. This joined space and time into one mathematical description. Later in 1907, a chap called Herman Minkowski worked out that this was like treating time as a fourth dimension. It is not possible to describe spacetime in terms of the traditional geometry we learn at school. One of the consequences of the highly elaborate thinking and mathematics is that matter bends spacetime and other matter has to follow these bends. This is Einstein's description of gravity. It is quite different from Newton's description of gravity which still works as a model in most instances. However, sometimes the two models, Newton's and Einstein's, give different predictions about what would happen and Einstein's has been shown to be right by experiments.

Answer 4

Even though Einstein originated the Field equation , he did not have a mechanism for Gravity.
Therefore there is no explanation that Einstein Understood to this reguard.
You what to know about gravity you need to reword your question.

Answer 5

This arises from Einstein's General theory of relativity and the observation that light is bent when it passes a massive object like the sun. Einstein suggested that this effect is caused by the curvature of space itself. The curvature of space offers an entirely new concept of the force of gravity.The moon, for example, could be regarded as following a 'straight line' course within the curved space produced by its own mass and that of the earth.

Answer 6

an apple dropped on his head and when it feel, something must be pulling it to the centre of the earth, so he called it gravity
