BOSTON -- Scientists might soon have evidence for extra dimensions and other exotic predictions of string theory, according to researchers at Northeastern University in Boston and the University of California, Irvine. Early results from a neutrino detector at the South Pole, called AMANDA, show that these ghostlike particles from space could serve as probes to a world beyond our familiar three dimensions, the research team says...

CAMBRIDGE, Mass. -- By a score of 135 to zero, scientists at MIT and Harvard have found that a certain type of X-ray explosion common on neutron stars is never seen around black holes, as if the gas that fuels these explosions has vanished into a void. This is strong evidence, the team said, for the existence of a theoretical border around a black hole called an event horizon, a point from beyond which nothing, not even light, can escape...[read more]

CAMBRIDGE, Mass. -- MIT scientists and their colleagues have found a black hole that has chiseled a remarkably stable indentation in the fabric of space and time, like a dimple in one's favorite spot on a sofa. The finding may help scientists measure a black hole's mass and how it spins, two long-sought measurements, by virtue of the extent of this indentation...[read more]
