| Accretion onto black holes is responsible for some of the most energetically spectacular phenomena in the universe, from gamma-ray bursts to quasars. Unfortunately, despite tremendous progress on the observational side, our theoretical understanding of the nature of the accretion flow close to the black hole has been hampered by fundamental uncertainties that have stymied progress in the field for decades. Thanks to new physical insights and increasingly sophisticated numerical simulations that are capable of treating more and more of the physics, the situation is changing rapidly for the better. I will review some of the theoretical breakthroughs related to radiation pressure dominated flows that are relevant to the brightest sources, and describe new ideas that these results have generated that might help explain observations of X-ray binaries. |
