Black Holes Could Become Massive Particle Accelerators
Paul Sutter: Black holes are powerful engines of pure gravity, capable of pulling on objects so intensely that they can’t possibly escape. When those objects near the event horizon, they’re accelerated to incredible velocities. Now, some physicists are suggesting harnessing the gravitational pull of black holes to create ferocious particle accelerators. The trick, the new study finds, is to carefully set everything up so that particles don’t get lost forever in the insatiable black hole. This new insight may help us identify black holes from the streams of particles blasting away from them.
