Dark Matter from AMS? Not really…
Here’s a refreshingly hard-nosed take on the recently-announced results from the Alpha Muon Spectrometer (which were rather excessively hyped, in my opinion…)
The Alpha Magnetic Spectrometer [AMS] finally reported its first scientific results today. AMS, a rather large particle physics detector attached to the International Space Station, is designed to study the very high-energy particles found flying around in outer space. These “cosmic rays” (as they are called, for historical reasons) have been under continuous study since their discovery a century ago, but they are still rather mysterious, and we continue to learn new things about them. They are known to be of various different types — commonly found objects such as photons, electrons, neutrinos, protons, and atomic nuclei, and less common ones like positrons (antiparticles of electrons) and anti-protons. They are known to be produced by a variety of different processes. It is quite possible that some of these high-energy particles come from physical or astronomical processes, perhaps very exciting ones, that we have yet to discover. And…

Balloon inside balloon theory of matter and antimatter universe ON OPPOSITE ENTROPY PATH producing dark energy at common boundary and injected into both the universe etc etc —-more in attached papers published long back and Dr. Guth inflation mechanism also explained by OPPOSITE ENTROPY PATH AND RE BOUNCE ETC ETC .–durgadas.ddatta@gmail.com

There has been a recent confirmation:

This is a bad case of overhype. AMS-02 has performed excellent, high precision work. However, the CERN press release implied they were now on the verge of discovering dark matter. This message isn’t supported by the results in the paper. In spite of the hype, this paper didn’t teach us much more than we already knew from previous experiments.
I know a few folk who think that Ting has a discovery up his sleeves in the higher mass region. He has hinted this may be the case. However, he hyped up this paper as well and, in relation to the claims in the press release, it was a damp squid. Also, even if AMS-02 did come up with a stronger DM-signal, inherent limitations in our understanding of the channels, would prevent this from being a “smoking gun” signal.
