Black hole model
Numéro d’image : 11885792
| Black hole. Computer model of the turbulent accre- tion disc around a non-rotating (Schwarzschild) black hole. The colours show the amount of red shifting (decreasing from red to blue) in the disc,which is rotating anticlockwise around the hole. Red shift occurs when a light source moves away from an observer,increasing its wavelength. Turbulence slows orbiting matter in the disc,allowing it to fall into the hole. Near the hole the disc is smooth. Turbulent discs such as this may be the source of the radiation associated with quasars. Black holes are regions where the gravitational field is so strong that light cannot escape. Work done at the University of Utah,USA | |
