A high-energy chain reaction NASA
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…
