Solving the gravitational N-body problem in general relativity
New York NY (SPX) Jul 10, 2015
Recent experiments have successfully tested Einstein's general theory of relativity in a variety of ways and to remarkable precision. These experiments included spacecraft Doppler tracking, planetary radar ranging, lunar and satellite laser ranging, as well as a number of dedicated gravitational experiments in space and many ground based efforts. How can computational models keep up with the ever improving accuracy of these missions? Finding a solution to the Einstein's gravitational field equatio ... read more

Biggest explosions in the universe powered by strongest magnets Gamma-ray bursts are one of the outcomes associated with the biggest explosions to have taken place since the Big Bang. They are detected by orbiting telescopes that are sensitive to this type of hi ... more		A black hole under the gravitational lens Turbulent processes take place close to supermassive black holes, which lurk in the centres of nearly all galaxies. They swallow up matter flowing in from the outside while at the same time producin ... more		The dark side of galactic radio jets Cosmic microwave radiation points to invisible 'dark matter', marking the spot where jets of material travel at near light speed, according to an international team of astronomers. Lead author Ruper ... more
				Super-bright supernova with extreme burst of gamma radiation Astronomers from the Niels Bohr Institute have observed a super-bright supernova association with a very unusual long lasting gamma-ray burst. Gamma-ray bursts are in rare cases observed in connecti ... more		A five star, doubly-eclipsing star system Astronomers at the Open University have discovered the first quintuple star system containing two eclipsing binary stars. Details of the five star system, the first of its kind to be found, will be ... more

Does the solar magnetic field show a North-South divide? A study of jets travelling through the Sun's corona at speeds between 200-500 kilometres per second has shown that the fast-moving columns of plasma are deflected much more strongly by the Sun's mag ... more		New method of quantum entanglement packs vastly more data in a photon A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart t ... more		EU states to hold talks on 'drone wall' to protect bloc Denmark military intel fails to identify source of drone flights Lithuania eases rules on shooting down drones		Clues to inner atomic life from subtle light-emission shifts Atoms absorb and emit light of various wavelengths. Physicists have long known that there are some tiny changes, or shifts, in the light that gets absorbed or emitted, due to the properties of the a ... more

When you spill a bit of water onto a tabletop, the puddle spreads - and then stops, leaving a well-defined area of water with a sharp boundary. There's just one problem: The formulas scientists use ... more		Early Titan Was a Cold, Hostile Place For Life Titan is a mysterious orange-socked moon of Saturn that is exciting to astrobiologists because it has some of the same kinds of chemicals that were precursors to life on Earth. It also has a hydrolo ... more
