Question

What is the orgin of gravity?

Is it the warping of the fabric of space time or is it due to particles called gravitons?

Answer 1

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass.
It is here that Einstein connected the dots to suggest that gravity is the warping of spaceand time. Gravity is the curvature of the universe, caused by massive bodies, which determines the path that objects travel. ... In Einstein's view of the world, gravity is the curvature of spacetime caused by massive objects
