Can black holes be formed by focusing radiation?
Black holes are extreme outcomes of general relativity, and can form through a variety of ways, including gravitational collapse of massive stars, or quantum fluctuations in the early Universe. Here, we ask the question of whether they can form via focusing of radiation by compact binaries or intense lasers, or via trapping at the light ring of black holes. We provide evidence that gravitational lensing of radiation from a small, finite number of sources is not a viable mechanism to form black holes.
