What Would It Look Like To Fall Into a Black Hole? 154

CNETNate writes "A new video simulation developed by Andrew Hamilton and Gavin Polhemus of the University of Colorado, Boulder, on New Scientist today, shows what you might see on your way towards a black hole's crushing central singularity. Hamilton and Polhemus built a computer code based on the equations of Einstein's general theory of relativity, and the video produced allows the viewer to follow the fate of an imaginary observer on an orbit that swoops down into a giant black hole weighing 5 million times the mass of the sun, about the same size as the hole in the centre of our galaxy. The research could help physicists understand the apparently paradoxical fate of matter and energy in a black hole."

Astronomers Dissect a Supermassive Black Hole 77

Matt_dk sends along a piece from the European Southern Observatory, which reports on observations of the so-called "Einstein Cross," a fortuitous conjunction of a nearby galaxy and a distant black hole. A team of researchers from Europe and the US combined the effects of macrolensing (from the intervening galaxy) and microlensing (from stars in that galaxy), captured by an earth-bound telescope. "Combining a double natural 'magnifying glass' with the power of ESO's Very Large Telescope, astronomers have scrutinized the inner parts of the disc around a supermassive black hole 10 billion light-years away. They were able to study the disc with a level of detail a thousand times better than that of the best telescopes in the world, providing the first observational confirmation of the prevalent theoretical models of such discs."
