WebAccording to Einstein, an object's gravity is a curvature of space. You can visualize Einstein’s gravity warp by stepping on a trampoline. Your mass causes a depression in the stretchy fabric of space. Roll a ball past the warp at your feet and it’ll curve toward your mass. The heavier you are, the more you bend space.
How a weird theory of gravity could break cause-and-effect
In physics, theories of gravitation postulate mechanisms of interaction governing the movements of bodies with mass. There have been numerous theories of gravitation since ancient times. The first extant sources discussing such theories are found in ancient Greek philosophy. This work was furthered by … See more Greco-Roman world The Ionian Greek philosopher Heraclitus (c. 535 – c. 475 BC) used the word logos ('word') to describe a kind of law which keeps the cosmos in harmony, moving all objects, including … See more In the 14th century, both the French philosopher Jean Buridan and the Merton College of Oxford rejected the Aristotelian concept of gravity. They attributed the motion of objects to an impetus (akin to momentum), which varies according to velocity and mass; … See more In 1900, Hendrik Lorentz tried to explain gravity on the basis of his ether theory and Maxwell's equations.
