Journey To The Limits Of Spacetime. Hypothetically. With A Computer

Last month, physicists predicted the formation of accretion disks and relativistic jets that warp and bend more than previously thought, shaped both by the extreme gravity of black holes and by powerful magnetic forces generated by their spin.  Black holes, absences at the center of both galaxies and science fiction, shape the growth and death of stars around them through both their powerful gravitational pull and explosive ejections of energy - a pull so strong close to a black hole that even light cannot escape from within, hence the difficulty in observing them directly.  read more
