• Gravitational wave radar could probe deep space for tiny stellar objects

    10 days ago - By Science Mag

    Theoretical physicists have hit on a new way to test Albert Einstein's theory of gravity, or general relativity, and-just maybe-probe the distant universe for tiny, hard to detect objects.
    Gravitational waves
    -ripples in space set off when massive objects such as black holes whirl together and collide-should bounce off other massive objects to produce echoes of the signals coming directly to Earth, the theorists predict. Such “gravitational glints” might serve as a kind of radar to detect white dwarfs, neutron stars, and other stellar corpses that are difficult to see beyond our galaxy.
