So does gravity even really exist?
Isn't it just a by-product of mass?
Gravity is the name we give to the property of matter which causes curvature of space-time
Bodies with mass will appear to attract each other because they're curving space time?
is probably a better way to say it.
gbj_tester-
MASS (or energy density) is the name we give to the property of matter which causes curvature of space-time,
Gravity is the name we give to accelerations dependent on a bodies mass (or energy density).
Which is somewhat semantics but ultimately mass/energy tells space how to warp and space tells mass/energy how to move.Technical addon:
[G=(8*pi*g)*T], where G is space time curvature and T is energy density, the rest just constants.
