Nima Arkani-Hamed (06:09): "Almost all of us believe that spacetime doesn't really exist, spacetime is doomed and has to be replaced by some more primitive building blocks."x https://www.youtube.com/watch?v=U47kyV4TMnE

Yet all those who believe that spacetime doesn't really exist still worship LIGO's ripples in spacetime. Nima Arkani-Hamed and his brothers string theorists believe that ripples in spacetime can exist in the absence of spacetime, in the same way in which the Cheshire cat smile exists in the absence of the cat.
