Feynman-"what differs physics from mathematics"
Black holes are a mathematical result. Because of that, we are searching for mathematical behavior in the real world. The person in the video above won a Nobel prize, still - who cares, there are 50 years of black holes and every laboratory and career built around this math.
There is no square root of -1 in the real world. The usage of imaginary numbers for circuit analysis is just a mathematical tool, used to simplify calculations. Else, we should build labs and telescopes maybe, to search for imaginary quantities in the real world, just because they do exist in math.
A quadratic equation, with 2 solutions, one positive, one negative. But we know that the results are distances. If no common sense is applied, I am sure someone would be happy to build a lab to search for "negative distance".
