Astrophysics: Bringing black holes into focus
Christopher S. Reynolds1
Abstract
Do black holes exist? Observations at the finest resolution so far indicate that only gross deviations in the behaviour of gravity from that predicted by general relativity can invalidate the case that they do.
It is believed that the centre of essentially every galaxy, including our own, plays host to a supermassive black hole. In a small fraction of galaxies, large quantities of gas rain down into these giant black holes, causing the black hole to grow while releasing enough energy within the central few light hours of the galaxy to outshine all of the galaxy's stars thousands of times over.
