Since our best theory of gravity at the moment is Einstein's general theory …showed first 75 words of 3654 total…

And, just as X-rays brought a completely new universe into focus, one can hardly imagine what a gravitational view of the universe will reveal. At the very least, we will have definitive proof or denial of black holes, but we may find that black holes are some of the more subtle features of the universe.
