A high-speed collision between particles can, theoretically, concentrate enough mass and kinetic energy in one place that a black hole can form. Physicists have considered this possibility for some time, but new dynamical simulations show that the amount of collisional energy needed is 2.4 times less than previously assumed. The authors, reporting in Physical Review Letters, explain that the colliding objects act like gravitational lenses on each other, focusing the energy into two light-trapping regions that eventually coalesce into a single black hole.
