XKCD Significant-Speed of Light Issue?

Posted on October 27, 2011 by PlatoHagel

You got to love it when correlations can be made, and a thank you to the ICECUBE Blog If the histograms and data are exactly right, the paper quotes a one-in-ten-thousand (0.0001) chance that this bump is a fluke. That’s … Continue reading →

Cherenkov radiation

Posted on October 4, 2011 by PlatoHagel

Taking the formalisms of electromagnetic radiation and supposing a tachyon had an electric charge—as there is no reason to suppose a priori that tachyons must be either neutral or charged—then a charged tachyon must lose energy as Cherenkov radiation[15]—just as … Continue reading →

P.I. Chats: Faster-than-light neutrinos?

Posted on October 4, 2011 by PlatoHagel

Measurements by GPS confirm that the neutrinos identified by the Super-Kamiokande detector were indeed produced on the east coast of Japan. The physicists therefore estimate that the results obtained point to a 99.3% probability that electron neutrino appearance was detected.Neutrino … Continue reading →

Geo-neutrinos

Posted on April 22, 2011 by PlatoHagel

The main geophysical and geochemical processes that have driven the evolution of the Earth are strictly bound by the planet̓s energy budget. The current flux of energy entering the Earth’s atmosphere is well known: the main contribution comes from solar … Continue reading →
