New feature found in energy spectrum of universe’s most powerful particles – Phys.org

Particles smaller than an atom hurtle through the universe nearly at the speed of light, blasted into space from something, somewhere, in the cosmos.
A scientific collaboration of the Pierre Auger Observatory, including researchers from the University of Delaware, has measured the most powerful of these particlesultra-high-energy cosmic rayswith unprecedented precision. In doing so, they have found a “kink” in the energy spectrum that is shining more light on the possible origins of these subat…
