Tests for general relativity
As a theorist, I’d guess that in Newtonian gravity we can check for proportionality to mass, and inverse square proportionality to distance, by measuring the ratios of gravitational forces.
Is there ...

Experimental Test for the cyclic $G_{earth}$ prediction of a Cosmological Model
Can anyone suggest a way to measure or rule out a tiny cyclic variation in the earth’s gravitational constant $G_{earth}$, predicted by an alternative cosmological model? It’s an annual cyclic ...

Are physicists still ignorant of the existence of real singularities?
(1) Is the gravitational singularity (or space-time singularity) the same as the black hole singularity?
(2) The wikipedia page says
Physicists are undecided whether the prediction of ...

Any method to determine the gravitational constant $G$ from observations in cosmological scale?
By the observations in cosmological scale, I mean observations by astrophysicists like motions of quasars in far distance from us, relative motions of our galaxy to others, etc.
I know the famous ...
