<< Einstein discovered that there is a relationship between mass, gravity
and spacetime. Mass distorts spacetime, causing it to curve. Gravity
can be described as motion caused in curved spacetime .

[no mention of energy there]

Thus, the primary result from general relativity is that gravitation is a
purely geometric consequence of the properties of spacetime.
Special relativity destroyed classical physics view of absolute
space and time, general relativity dismantles the idea that spacetime
is described by Euclidean or plane geometry. In this sense, general
relativity is a field theory, relating Newton's law of gravity to the
field nature of spacetime, which can be curved..>>

<<this deformation has the aspect and equivalence to energy?>>

The *intent* is reflected in much of the work. But the proof is
in the pudding. So much of the convolutions with time (energy's
second closest relative ) are to effect Lorenz gauge invariance it is
hard to see in the theory or any real world application of the theory
a definite relation between gravity and energy.

Some might cite cosmic expansion but I regard it as conjucture
die hard skeptic that I am.
