This Year, We’ll See a Black Hole for the First Time in History
Within the next 12 months, astrophysicists believe they’ll be able to do something that’s never been done before, and it could have far-reaching implications for our understanding of the universe. A black hole is a point in space with a gravitational pull so strong that not even light can escape from it. Albert Einstein predicted the existence of black holes in his theory of general relativity, but even he wasn’t convinced that they actually existed. And thus far, no one has been able to produce concrete evidence that they do. The Event Horizon Telescope (EHT) could change that.

Chicken and egg? Is it right to attribute black holes to Einstein just because they can be studied by his GR theory?
Black holes came after his 1915 publication and were studied by Swarzschild who found the Swarzschild radius for a massive object. Essentialy the limit size of an object where light can't escape if the object is smaller. The idea of a black hole in such circustances is rather simple: Find the limit where the escape velocity becomes the speed of light.
Do I have to quote Einstein for everything I do?
