What scientific idea is ready for retirement? Steve Giddings: "Spacetime. Physics has always been regarded as playing out on an underlying stage of space and time. Special relativity joined these into spacetime... [...] The apparent need to retire
classical spacetime as a fundamental concept is profound..."

"Was Einstein wrong? The case against space-time theory. If Einstein was wrong, could killing off space-time theory help us better understand the universe?"

Space-time is a corollary of Einstein's constant-speed-of-light postulate. If it is wrong and should be retired/killed off, the postulate is false. Simple logic.
"Einstein pulled all of these ideas together in his 1905 theory of special relativity, which postulated that the speed of light was a constant. For this to be true, space and time had to be combined into a single framework that conspired to keep light's
speed the same for all observers."
