By making precise measurements of gravitational radiation, astronomers will be able to test the predictions of Einstein's Theory of General Relativity. Scientists want to know, "Does time really freeze near a black hole? How stretched-out is spacetime when we get close to a huge mass?" Strong gravitational wave sources like black holes should be able to give us a picture of the 'knots' in spacetime--areas where gravity has such strong effects that it 'ties' matter in, and the matter cannot escape. Interesting sources like these will enable LISA to map out the area around a black hole, in order to confirm the predictions of General Relativity.
