Actually, “dark photons” probably don’t exist

Yesterday, we noted the hunt for a mysterious fifth force of the universe involving dark photons. Here’s an item from last April that suggests the hunt may prove a disappointment:

But the most precise measurement yet of the fine structure constant — which determines how strongly electrons and photons interact, or “couple” — has eliminated the possibility of dark photons at a large range of masses and coupling strengths. If they did exist, they would have to be much heavier than previously predicted, scientists wrote in a new paper describing the work.

One possible hope:

However, there’s still a narrow escape path, through which theoretical dark photons could escape the dustbin of discarded physics theories. The field of particle physics has a general standard for measuring the significance of results: Typically, a truly significant resultmust have less than a 1-in-3.5-million probability of being due to random chance, which is a “5-sigma” level of significance. In this case, the difference between this measurement and the previous most-precise measurement is only a “2.5-sigma” level of significance, or a 1-in-200 probability of being due to random chance — far too likelyto meet thestrong standard of the field.

Realistically, the Standard (Big Bang) Model of the universe is not in anywhere near enough trouble for this stuff to seem credible, though it is fun to look at.

It amazes me completly - here you have a theory built up over 100 years. And then one day a guy builds a computer model (in the proper way - to model systems not future events ini a complex system like climate), to show how universes hold together and don't fly apart. After adding tons of mass from things like brown dwarfs and other sources, which is fair as much of the gravity in a universe is from sources that, as far as quantity go, we can only theorize. No matter how he modeled it, universes should fly apart. So the solution, just add more matter, much more than regular matter. in a similar way the far to rapid expansion of our universe requires that by far most of the energy in our universe is also "dark", Energy. Missing energy, just add more and say we can't see it but we can see its effects. Not enough matter, just add "dark" matter that we can't see, but only observe. My problem with this is, the Energy and Matter would have to be uniform - but when you see it presented as fact on popularized science shows, they color in areas where the dark matter "is", cue to the effects we apparently see. There are other solutions and explanations that do not require dark matter and dark energy, but I believe why these alternatives (like the universe is NOT accelerating apart, but that there is something wrong with the measurements we use, or a problem with one of the other thousands of sub-theories that the "consensus" and lobbyist that need more money to pull another rabbit or particle out of the hat to explain things away and make it all better - this seems to be the first reaction when issues like this arise, same with Evolutionary Biology, The fanciful storytelling that "Must be True", and when issues arise, it is simply covered up with absolute assumption. I think the same thing is happening in cosmology - they have doubled down too many times to entertain any other notions, or go back and challenge some long held beliefs that support the current paradigm. If one day you realize by your current supposidly correct beyond dispute theories runs into the problem where 80% of what you are trying to model, comes up missing, one should re-examine every assumption and measurement associated with your current model. It is for this reason I do not think we will ever find Dark Matter or Dark Energy, which is very odd as if it takes up that huge a percent of the matter and energy, we should certainly be able to detect it right here on earth. We should also be able to see its impacts right here on earth, but of course we don't. I think this is the fact that makes me most suspicious - it seems to be all "out there" and for some reason nothing on earth, or in orbit, or a spacecraft can detect it? Seems to me this is ridiculous. Tom Robbins
