This is demonstrably false. Dozens of experiments have measured gravity at varying levels. None have observed any "jumps" in gravitational energy.
If you can point to 1 study showing these supposed "jumps" in gravity then you may be on to something.
I have seen no experiment that tries to measure continuity, which is the key issue. There is no debate on the concept of gravity decreasing with altitude, but it is assumed to be continuous: this is not tested for.
This is an example of an experiment that count be performed, not one that has been.
Here's the thing though, one cannot possibly measure for continuity. How would it be recorded?
The only way anybody can make any sort of accurate measurement of anything in the world is to measure it at discrete intervals and record the findings.
As it stands, NOT ONE SINGLE TEST regarding the effects of gravity has found ANY evidence of the "jumps" you speak of. In fact, every single time gravity is measured at different altitudes, one reliably finds a GRADUAL DECREASE in gravitational energy as one moves further away from the source.
AGAIN, if you can point out ONE SINGLE TEST that finds irregular "jumps" in gravitational energy, you would have a leg to stand on.
Currently, you do not.
