Thanks BenLurkin. M Theory, surprisingly, didn't originate at British intelligence. Okay, so that one needed more work.

For decades physicists have tried to rectify the Standard Model of Particle Physics, which is great at describing the behavior of particles, interactions, and quantum processes on the micro scale, with gravity...the Standard Model, as it is currently constructed, fails to account for gravity at this extremely small scale.
...a number of mathematical models have been proposed that would unify these disparate phenomena, including something called string theory [and] a number of these models feature elements that can be tested in a lab setting. One is known as the Pauli exclusion principle.
Pauli exclusion basically means that no two electrons can have the same quantum state. The practical result of this principle is the fact that matter cannot pass through matter.
To test certain quantum gravity models that predict violations of Pauli, Curceanu and her colleagues went deep underground...
First, they brought along a thick block of good old-fashioned Roman lead. Then, next to the lead block, they placed a device known as a germanium detector. In this “cosmically silent” setting, the detector is sensitive enough to pick up the smallest signs of radiation emanating from the lead. This is key because if Pauli is violated, a forbidden atomic transition will occur, resulting in the generation of an X-ray with a distinct energy signal. The germanium detector can pick up this signature x-ray, essentially proving that Pauli has been violated. If that happens, this X-ray signature would be extremely strong evidence supporting the theoretical models that unify the Standard Model and quantum gravity, including certain string theory models.
After shielding their Roman lead and running their experiments, Curceanu and her team made a discovery, or in this case, a lack of discovery of the telltale X-ray that would mean Pauli was violated.

The experiment discredits a quantum gravity theory...
In other words, we’ll keep looking until we find what we want to or when the money runs out.

This is very encouraging. At least to me.
But can you imagine how depressing this must be to thousands of wanna-be-scientists? For an entire career they have been preaching stuff that not only does not exist, but has now been proven to not exist.
Okay, so I may have overstated the “existence” part. After all, it is THEORETICAL physics.
BTW - Isaac Newton is waiting for some apologies. LOL
Nothing is news.
Well, some of them at least.
I listened to an audiobook: Three Roads to Quantum Gravity by Lee Smolin
Different theories were discussed and the author said something like “experts believe that answers are close and believe the answer will be determined within the next 10 years”.
The original edition was released around the turn of the century with an updated edition in 2018 that said “not yet, but definitely within the next 10 years”
Wouldn’t it be easier if they’d just look under a bed for it? Probably the same chance of finding it and would be cheaper.
More hogwash!
The point of string theories and quantum gravity theories is to unify quantum mechanics and relativity, two of the foundational and most productive theories of modern science. If that effort is successful, transformational new forms of energy and space travel could follow within a few decades. In other words, kids now in preschool could, in early middle age, enjoy abundant cheap, clean energy and undertake routine space flight around the solar system and aim for distant stars.
In the meantime, a relative handful of physicists and technicians earn enough to buy bread and fill their gas tanks as they putter about with equations on chalkboards and twiddle with odd devices deep underground. Forget Marx, Lenin, and Mao. Physicists are the world's true revolutionaries.
I am not a theoretical physicist but it seems to me there are certain logical conclusions one can make of all this very simply.
Does a proton have weight? We assign it a weight. Does an electron have weight? Many may say no but in reality somewhere near 2000 electrons will have the same weight or mass as a proton. Is a proton affected by gravity? Ok, are 100 protons affected by gravity? Since if 100000 electrons have weight and are affected by gravity we are simply unable to measure the affect of gravity on very small amounts of mass. What ever subatomic particle you can name, if you have enough of them then you have an object(s) that are affected by gravity. Simply use Newtonian physics to explain it.
