Title
How Can We See a Black Hole?
Black holes are, by their nature, invisible. The Theory of Relativity tells us that they emit no light, and that no information of any kind can be conveyed from the interior of a black hole to the rest of the Universe. And yet, black holes have become well-studied astronomical objects. Astrophysicists routinely “observe” black holes in a variety of ways, and the origin and evolution of these physical constructs play a major role in our current understanding of the cosmos.
