Want a lovely GR thing.. Some experiments are.. attempting to be
constructed, I suppose you might say, since there is a thought that they
simply won't work at all, which will attempt to determine if you can
build the equivalent of a gravitational transformer. GR implies yes,
since for example, the clocks on a satellite do not "run" at the same
rate as their ground based systems, they are effected differently by the
speed, and level of gravity, in orbit. So.. the idea is to use one
gravitational effect to generate a field, which would *cause* a
gravitational effect in something else, in principle, similar to the
change in frequency and the like you get in an electrical transformer.
The problem being, it may simply not work, even if GR says it should,
and some effects imply that it happens, to an extent, already, just not
on what might be called a practical scale.
