So you are telling us that mass and energy do not alter the curvature of spacetime?

There is no such thing as time, hence no such thing as spacetime.
Light & em radiation do bend due to the presence of mass (but not due to the presence of energy)(there is no such thing as energy).
Einstein made a correct prediction (re light bending near mass), but for wrong reasons (called equivalence).

If Circlotron send signals to the top of his 100m antenna he will find that he has a big MMX kind of experiment on his hands -- koz electricity on a wire is due to photons (electons) propagating on the surface of the Cu -- & the propagation speed is say 1c/1 in air, & 2c/3 if insulated Cu -- the real problem being that the speed of electricity is affected by the aetherwind blowing throo the antenna -- the aetherwind is say 500 km/s south to north about 20 deg off Earth's axis -- hence the speed of electricity varies during a day (due to Earth's spin & alignment) & during a year (due to Earth's orbit) -- & this is just the start of Circlotron's problems.

This forum member has written lots of nonsense in many threads. There can't be any discussion - he just enjoys provocation and confusion.
Time and energy are extremely useful concepts in physics as is the progress Albert Einstein made long time ago in various areas of physics. General relativity is one of them and there have been several successful experimental verifications. Once more i'd recommend reading Wikipedia instead,

Time and spacetime are not the same thing.  Are you sure you understand what Einstein's General Relativity is?
