Quote:Albert Einstein is admired for pioneering the use of thought experiments as a tool for unraveling the truth about the physical reality. But we should keep in mind that he was wrong about the fundamental nature of quantum mechanics as well as the existence of gravitational waves and black holes—which he dismissed late in his career, and which were both confirmed observationally by LIGO in 2015, exactly a century after he formulated the general theory of relativity.

Given this humbling historical lesson, theoretical physicists should be careful of premature hubris in celebrating conjectures and accept the final verdict of experimental guillotines in setting the fate of untested speculations.
