Physicists Try to "Big-Mystery-Glamorize" Their Pigeonhole Pet Projects

 Scientists believe that when two very high-energy photons collide, they produce equal amounts of matter and antimatter, and that when matter collides with antimatter, it is converted into high-energy photons. Such a belief is based on what scientists have observed in particle accelerators such as the Large Hadron Collider, where particles are accelerated to near the speed of light before they collide with each other. But such conclusions about matter, antimatter and photons lead to a great mystery as to why there is any matter at all in the universe.

Let us imagine the early minutes of the Big Bang about 13 billion years ago, when the density of the universe was incredibly great. At that time the universe should have consisted of energy, matter and antimatter. The energy should have been in the form of very high-energy photons that were frequently colliding with each other. All such collisions should have produced equal amounts of matter and antimatter. For example, a collision of high energy particles with sufficient energy creates a matter proton and an antimatter particle called an antiproton. So the amount of antimatter shortly after the Big Bang should have been exactly the same as the amount of matter. As a CERN page on this topic says, "The Big Bang should have created equal amounts of matter and antimatter in the early universe." 

But whenever a matter particle touched an antimatter particle, both would have been converted into photons. The eventual result should have been a universe consisting either of nothing but photons, or some matter but an equal amount of antimatter. But only trace amounts of antimatter are observed in the universe. A universe with equal amounts of matter and antimatter would have been uninhabitable, because of the vast amount of lethal energy released when even a tiny bit of matter comes in contact with a tiny bit of antimatter.

The mystery of why we live in a universe that is almost all matter (rather than antimatter) is called the baryon asymmetry problem or the matter-antimatter asymmetry problem.  There is not much of a prospect that this problem will be solved in our lifetimes.  It's like the problem of "why is there something rather than nothing?" That's not a problem we can expect to solve in our lifetimes. The infographic below explains this matter-antimatter asymmetry problem. 

But sometimes when scientists have embarked on a boondoggle costing billions, they may evoke the matter-antimatter asymmetry problem to try to sanctify their misguided schemes.  That is what is going on with various boondoggle projects researching neutrinos. They include these projects:

• An ongoing T2K experiment in Japan that beams neutrinos over a distance of 295 kilometers. 
• An ongoing 280-million-dollar NOVA experiment in the USA that beams neutrinos 804 kilometers (500 miles), from the Fermi National Accelerator Laboratory in Illinois to a 14,000-ton detector in Ash River, Minnesota.
• An under-construction 3-billion-dollar DUNE experiment in the USA that will attempt to beam neutrinos 1300 kilometers (800 miles), from the Fermi National Accelerator Laboratory in Illinois to a very-deep-underground facility in Lead, South Dakota. 

The first two experiments have been running for years, and there was recently released a paper announcing a kind of combined results from the projects. Nothing of any importance was found.  But you might think otherwise from some of the press coverage, some of which attempts to make this "found nothing" result sound like something worthwhile. 

Scientists were hoping to find evidence of something called "mass ordering" or something else called "inverted ordering," but the paper says, "The data show no strong preference for either mass ordering."  We read, "There is no statistically significant preference obtained for either of the mass orderings." We also read, "We do not see a significant preference at present for either mass ordering."  

The only thing the paper authors say on the question of the matter-antimatter asymmetry is, " It is unknown whether neutrinos—and thus leptons—violate charge-parity (CP) symmetry and thereby provide a source of matter–antimatter asymmetry in nature, which is of great interest given the connection between CP violation and the unexplained matter dominance in the Universe." Since the paper says nothing else on the topic of matter-antimatter asymmetry other than this "say nothing" sentence,  the results obtained utterly fail to shed any light on the mystery of matter–antimatter asymmetry, contrary to the sales pitches for these very expensive projects, which tried to suggest that they would give important insight on this topic. 

The Reuters article on this paper describes it without exaggeration, and does not claim that the work shed any light at all on the matter-antimatter asymmetry problem. We have a headline of only "Researchers in US and Japan offer insight into ghostly neutrinos."

A Caltech press release on the paper uses some scrambled reasoning to gin up some relevance to the results. It states this:

"The combined results of NOvA and T2K so far do not favor one mass ordering scenario over another. However, if future results show the neutrino mass ordering is inverted and not normal, NOvA's and T2K's results published today provide evidence that neutrinos do exhibit the suspected asymmetry, potentially explaining why the universe is dominated by matter instead of antimatter. "

This is  kind of like someone saying, "My photo published today of triangular marks in the mud provides no evidence of extraterrestrial creatures; however if it is proven in the future that there are extraterrestrial visitors with triangle-shaped feet, then my photo published today potentially provides evidence of such creatures." 

In the article here, a Professor Yu speaks in a silly way. We read,  "Professor Yu said, 'Given these results, we expect that next-generation neutrino research facilities such as Japan’s Hyper-Kamiokande or America’s DUNE will discover matter–antimatter asymmetry,' adding, 'We anticipate being able to understand why matter exists in overwhelmingly greater amounts than antimatter in the universe.' ”  But we already know that matter-asymmetry exists, so it makes no sense for Yu to be claiming that it will be discovered by the still-under-construction DUNE project. That's as silly as saying that you anticipate that some new project will discover that the sun exists. There is no basis whatsoever for the described "anticipation." The new paper describes 14 years of expensive neutrino search that failed to shed any light on why "matter exists in overwhelmingly greater amounts than antimatter in the universe."

We can describe the neutrino study projects listed above as "pigeonhole pet projects." That's because they are investigations of some topic of no interest to the general public, and only of interest to a very small number of physicists, such as neutrino specialists. If you are a scientist trying to get funding for one of these pigeonhole pet projects that are of no interest to 99% of the public, what sales strategy can you take? One strategy: try to make your little pigeonhole pet project sound like it has some relevance to some grand mystery that people are interested in.
