In physics, gravitation or gravity is the tendency of objects with mass to accelerate toward each other. Gravitation is one of the four fundamental interactions in nature, the other three being the electromagnetic force, the weak nuclear force, and the strong nuclear force. Gravitation is the weakest of these interactions, but acts over great distances and is always attractive. In classical mechanics, gravitation arises out of the force of gravity (which is often used as a synonym for gravitation). In general relativity, gravitation arises out of spacetime being curved by the presence of mass, and is not a force. In quantum gravity theories, either the graviton is the postulated carrier of the gravitational force[1], or time-space itself is envisioned as discrete in nature, or both.

The gravitational attraction of the earth endows objects with weight and causes them to fall to the ground when dropped (the earth also moves toward the object, but only by an infinitesimal amount). Moreover, gravitation is the reason for the very existence of the earth, the sun, and other celestial bodies; without it matter would not have coalesced into these bodies and life as we know it would not exist. Gravitation is also responsible for keeping the earth and the other planets in their orbits around the sun, the moon in its orbit around the earth, for the formation of tides, and for various other natural phenomena that we observe.

push and pull.

Einstein's description of gravity is equivalent to displacement. Mass displaces empty area. Atoms are as a rule empty area so the thought that displaced empty area can push back on an atom isn't far fetched. Scientists have been initially incorrect regarding the circulate of electricity and gravity is maximum possibly the comparable. to this point as black holes are in contact, the fact that they grow to be dense ought to help the frenzy hypothesis. If gravity grew to become right into a pull, then a black hollow would not be a one dimensional factor yet a 2 dimensional ring. Gravity might stretch area time interior the middle of the black hollow. Telescopes have mentioned loopy magnetic fields close to black holes. it extremely is possibly vortexes led to with the aid of pushing, equivalent to tornados forming from wind.

Gravity is not a thing, therefore, it does neither. It is merely an attractive force between objects which is conditional upon proximity and location.
