Yes absolutely, but you should never forget what it is, a TINY sliver of

And maybe there comes a point when asking "maybe" stops being very
productive . Maybe there comes a point when asking "maybe" becomes just a
bit silly and maybe your time could be better spent investigating other
things. Part of the art of being a good scientist is having a hunch about
what deserves further investigation and what does not,

That was an engineering question not a scientific one.

There is no "might have" about it, they have detested EVIDENCE for dark
matter; but of course in physics, or in any other science, you never find
PROOF, you only get that in pure mathematics.

Maybe. And maybe a yet more sensitive detector will find it again, and
maybe a even more sensitive detector will see precisely nothing once more,
and maybe a [...] As I said, once you get into a infinite loop you can
"maybe" yourself to death.

Maybe. But then again maybe not. You can't sit on the fence forever,
eventually you've got to make a stand. Maybe future generations will see
you as a visionary for taking that stand, maybe they will see you as a
fool, and maybe they will see you as somebody who did the best he could
with the evidence he had. Nothing is certain in life. Maybe.

I see no proof or even evidence that is happening, people still have a
right to make a fool of themselves. Denying the existence of Dark Energy
and Dark Matter hasn't yet reached the level of foolishness as denying that
the world is round, but it's getting there. Maybe.

We know that Einstein's General Theory of Relativity CAN NOT be even
approximately true and correct all the time because at the singularity in
the center of a Black Hole it produces nonsense results, and because it is
mathematically inconsistent with Quantum Mechanics. We need a quantum
theory of gravity to supersede relativity just as Einstein superseded
Newton, but we don't have such a theory yet; string theory wants to become
that theory but so far it is not.
