Field equation of Einstein;
Guv =( Lamda/energy density of space) x Tuv,
doesnt it relate to Newton Universal gravity constant and also to the curvature of mass as well?

Clarification;Lamda is Einstein's cosmological constant

The Einstein field equations (EFE) describe how stress-energy causes curvature of spacetime (not mass since mass and energy are equivalent) and are usually written in tensor form (using abstract index notation) as

Guv = κ Tuv

where Guv is the Einstein tensor, Tuv is the stress-energy tensor and κ is a constant. The tensors Guv and Tuv are both rank 2 symmetric tensors, that is, they can each be thought of as 4×4 matrices, each of which contains 10 independent terms.

The EFE reduce to Newton's law of gravity in the limiting cases of a weak gravitational field and slow speed relative to the speed of light. In fact, the value of κ in the EFE was determined to be

κ = 8πG/c^4

by making these two approximations, where G is Newton's Gravitational Constant.

i myself wish human beings could end making stuff up like "curvature of mass" or "speed of dark". i don't be attentive to the place human beings pay attention those issues, even if it beneficial ain't in Physics books or school rooms. It substitute into usual a protracted time in the past that area is curved.

the more dense the mass, the greater the curvature of spacetime. there is no curvature of "mass".

Woah that's beyond my brain copacity lol

But I have no idea...interesting question though :D

It don't take a genius to know that space can't have a shape, just stop that.
