Note that gravitational forces cause particles to move in vacuum but we are also familiar with particles moving "downwards" if placed on a nonflat surface
|
|
Einstein's theory of General Relativity is a brilliant generalization of this to describe all gravity in terms of structure of Space-Time
|
|
We do not say say the Earth creates a "Gravitational Force" which causes Apples to fall as noted by Newton
|
|
Rather The Earth distorts space-Time and Apples move in this distorted Space-Time
|
|
In Newton's law, gravitational force of Earth proportional to its Mass
|
|
In Einstein's description, distortion of Space-Time is proportional to Mass of particle
|
Everything (including you) distorts Space-Time;
-
This distortion is insignificant except for very Heavy Bodies
