The largest ARRA grant, from the NSF to Brau, will enable the UO's experimental relativity group to continue its search for vibrations in space, known as gravitational radiation. "Predicted by Albert Einstein's 1915 theory of general relativity, this radiation is generally expected to permeate the universe, but it has never been directly detected ... Indirect effects have been observed in the orbits of binary neutron stars, leading to the 1993 Nobel Prize (Russell A. Hulse and Joseph H. Taylor Jr., both of Princeton University). Once the radiation is detected, it will serve as a probe for new discoveries of outer space, as radio astronomy did with its development following World War II." The experimental relativity group has eight members, including two graduate students and one undergraduate. Full Article at Nanotech Now
