Cosmic Conspiracy Theories: Neutrinos and Gamma Rays from PKS 0735+178?

July 2023 Very-high-energy (VHE) gamma-rays studied with the H.E.S.S. telescopes are emitted by charged particles (mostly electrons and protons) that have been accelerated to very high energies. This ties gamma-rays to these highly relativistic…
