Scientists at the Norwegian University of Science and Technology propose that winds from supermassive black holes could accelerate ultra-high-energy cosmic rays, solving a puzzle dating back to 1962. These particles, mostly atomic nuclei, reach energies up to 10^20 electron volts. The hypothesis suggests these winds, moving at half the speed of light, fling particles across the cosmos.
