Physicists Spot Potential Source of 'Oh-My-God' Particles 144

sciencehabit (1205606) writes For decades, physicists have sought the sources of the most energetic subatomic particles in the universe — cosmic rays that strike the atmosphere with as much energy as well-thrown baseballs. Now, a team working with the Telescope Array, a collection of 507 particle detectors covering 700 square kilometers of desert in Utah, has observed a broad 'hotspot' in the sky in which such cosmic rays seem to originate. Although not definitive, the observation suggests the cosmic rays emanate from a distinct source near our galaxy and not from sources spread all over the universe.

    I have an idea backed only by my imagination.

    What if those galaxies are proof of symetry, and they're some of the few that are made of both matter and anti-matter, and the high energy ejections we're seeing are from that collision. Maybe half the galaxies in the sky are made of anti-matter and the non-particle-scale properties of antimatter are otherwise identical to matter.

      Collisions between matter and antimatter in space produce a lot of gamma rays of specific energies corresponding to the energy equivalence of the mass of the particles involved (not exclusively at those energies, but a lot there still). This has allowed scientists to characterize collisions between gas clouds and antimatter in areas around our galaxy, but they involve very, very small amounts of antimatter spread out over a large volume.

      As far as the discovery that these high energy particles might be coming from some place close, this was somewhat expected as the GZK limit [wikipedia.org] describes a process of high energy particles interacting with CMB photons to pair produce and lose energy, limiting the energy of high energy cosmic rays that travel a long distance. Unfortunately, that could mean there a lack of new physics involved at the cosmic ray energy, much in the same way that confirming a single Higgs particle is a boring outcome not hinting at post-Standard Model physics.

      • So to bring it around, what does that have to do with this specific observation in the article, because I can't quite bridge that connection in my head.

          The GZK limit predicts essentially a drag force on particles above a very large energy limit. Cosmic rays above this limit have been seen for some time now. This means either the particles come from somewhere close, before they have a chance to lose a lot of their energy, or they come from somewhere far away and the limit is wrong. Previous data was starting to lean toward the latter, with hotspots matching up with distance sources that match early theories on what could produce such high energy particles. Now those previous results didn't pan out, and these results are pointing more toward the former option, that such particles come from some place close and that the limit may still be valid.

      because the annihilation particles are all well known and have MUCH less energy than these particles.

      Ironically, these particles are named after exclamations. The God Particle was the name of a book originally titled The Goddamn Particle because the Higgs boson was so hard to find. A better name for the Oh-My-God Particle may be the Oh-Shit! Particle. The names have nothing to do with religion.

      Thanks. Just this, thanks, but sincerely.

    • other particles we find similar to it could be given normal names like UHE particles, or super high energy rays but that doesnt secure grant funding in the theocratic Mormon state of Utah.

      If the state of Utah is theocratic and makes funding decisions based on particle names, choosing blasphemous ones is not the path to big research bucks. Mormons take the prohibition against taking the name of deity in vain pretty seriously.

      This post made me remember an old short-story (whose name I've now forgotten) written by Larry Niven. The gist of the story was that some time way in the future when humans had colonized space and things were so peaceful and hunky-dory that they no longer fought wars or weaponized their spaceships, a human spacecraft came upon an alien ship manned by an unknown aggressive and warlike species (the Kzin, maybe), which began to attack them without warning.
