French astrophysicist Jean-Pierre Luminet created the first-ever simulation of a black hole, published in Astronomy and Astrophysics. Using an IBM 7040 computer and hand-plotting techniques with India ink, he calculated how light from an accretion disk would be distorted by gravity, producing a "distorted eye" image remarkably similar to modern direct imaging
It was, but it was first discovered by this guy first.
Relativity is fucking strange.
