Scientists explain how a 300 TeV photon reached Earth
Original: Scientists explain how a 300 TeV photon could reach Earth
Physicists have outlined an explanation for the detection of a photon carrying 300 tera-electronvolts of energy striking Earth, one of the highest-energy light particles ever observed. At such energies, photons normally should be destroyed by interactions with background radiation on their way through space, so researchers have proposed how it could survive the journey. The finding is drawing interest for what it says about extreme cosmic accelerators.
Why now: Ultra-high-energy photons challenge standard models of cosmic ray propagation, making the proposed explanation noteworthy.
