Black hole model Featured 9 Mar 2004 Print

Black hole model

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

Quantum entanglement apparatus Featured 9 Mar 2004 Print

Quantum entanglement apparatus

Quantum entanglement experiment. Face of a quantum physicist refracted in the lens of a receiver in a quantum entanglement experiment. Entanglement is a property of a pair of particles in which a change to one has an instantaneous effect on the other, no matter how far apart they are. Researchers at Vienna University, Austria, split an entangled photon pair, and sent each photon to a different receiver. There was no line of sight between the receivers, which were 600 metres apart, outside, on either side of the River Danube. Entanglement was confirmed by the detectors. It is hoped that this entanglement will find uses in cryptography, quantum computing and satellite communications
