Black holes have the weirdest kids. Three types of the highest energy particles in the cosmos could all be born in the chaos near a supermassive black hole
Three of the strangest sorts of particles that we can detect on Earth may all come from the same place. Ultra-high energy cosmic rays, high-energy neutrinos, and powerful gamma rays could all be born in the chaos of a black-hole jet.
Ultra-high energy cosmic rays come from space and have energies millions of times higher than anything we can produce in an accelerator on Earth. They were first discovered in 1962, and since then no one has been able to figure out for sure where they originate.
The same is true for neutrinos and gamma rays with extremely high energies. Now, Ke Fang at the University of Maryland and Kohta Murase at Pennsylvania State University have simulated a way to get all three types of particles from a single source.
The researchers suspected that these particles might share a common origin because they all bring
