Hi,
From what I know, science is the study of the observable world, its theories are supported by evidence.
Now GR is a theory, and it informs that mass curves the 'fabric' of space and time. The thing I don't understand is that there is no evidence of mass curving spacetime, then how is GR a theory? If there is evidence, then what is spacetime, really, since it's something which has the potential to be curved?
From what I know, in GR gravity is not a force, it's a curvature of spacetime. If so, force is needed to curve the spacetime, but where is that force in GR?
Thanks...
