Speed of light outside an imagined vacuum is not all that constant.
Wonder what it might be in a black hole or at a singularity? Also it
can be measured by physical experiments. Gravity, gravity waves, the
graviton, and quantum gravity - all remain `concepts'. All except the
acceleration produced by the force of gravity acting on a real mass,
which has been elegantly measured and described in relatively simple
experiments that anyone can perform and compare their results. If you
choose to view that force as a distortion of space, the results still
hold. Elegant mathematical concepts can't always be closely applied to
reality. The fact that the equations balance is nice but irrelevant
to reality.
I assume that your comment applies to all electromagnetic waves from
radio to cosmic (and beyond if they exist).

True experiments that give consistent results when other perform them.
Not to be confused with `Gedanken experiments' carried on in the inner
recesses of one's cave.

You practice an artful `science' but not a true scientific science.
These `gravity waves' must be your own cherished property. The tiny
polished balls in space and the long terrestrial tubes have had less
success. The ancient variety has had considerable success in guiding
people to space and on to the Moon and back.
It has also aided many generations of engineers in their constructive
efforts even such trivial pursuits as amusement park rides.
It has also made possible to a satisfactory degree of precision for
our needs, our mapping of the cosmos.

OK. I predict and assume that they are erroneous concepts incorrectly
applying mathematical concepts to reality. Now ball is back in your
court . Please furnish evidence that I am wrong.

Scientist ask many things - a lot of which scientists or science can
not answer. Meta physicists ask many questions that metaphysics can
not answer. And relativists and quantum mechanics ask a lot of
questions that the theories don't answer. Homo sapiens has been asking
a lot of `things' for a long, long time that they still can not
answer.

Then I take it that you are unfamiliar with the false `logic ' of the
dialectic, which claims it is a science and socialism or communism
(from a practical standpoint - tyranny) is its aim.
