MIAMIÂ -- Professor Stephen Haggerty retrieves a 730-carat black diamond _ the size of an apple _ from his desk. It's nearly impossible to cut, potentially billions of years old and, he believes, a product of outer space.

An international research team has found the first direct evidence that the Earth is dragging space and time around itself as it rotates, like a spoon spinning in honey.

Cambridge University -- Scientists have pieced together the journey of a bundle of doomed matter as it orbited a black hole four times, an observational first. Their technique provides a new method to measure the mass of a black hole; and this may enable the testing of Einstein's theory of gravity to a degree few thought possible...

At the center of a black hole there lies a point called a singularity where the laws of physics no longer make sense.

An international team of NASA and university researchers has found the first direct evidence of a phenomenon predicted in 1918 using Einstein&#39;s theory of general relativity -- that the Earth is dragging space and time around itself as it rotates.

The "supermassive" black holes at the centres of most galaxies could be spinning at a dizzying rate, scientists say.

PARIS -- Physicists have dreamt about it for decades: harnessing the fusion process that powers the sun to make clean, safe, and limitless energy. A multinational pact signed yesterday may bring that dream a step closer to reality.

By measuring variations in satellite orbits, scientists have found the first direct evidence of one of the hallowed tenets of Albert Einstein's theory of general relativity -- that the Earth and other large celestial bodies distort space and time as they rotate.

Einstein was right -- again. Satellites that have been pulled slightly off their orbits show that the Earth is indeed twisting the fabric of space-time as it rotates, scientists said on Thursday.

The phenomenon, known as frame-dragging, is quite small, amounting to 6 feet in the distance that satellites, moving at about 18,000 miles per hour, cover in their orbits in a year, but it is within the ability of NASA&#39;s instruments to detect.
