Re: How Crackpots and String Theorists Attack Einstein's Relativity

What scientific idea is ready for retirement? String theorist 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..." https://www.edge.org/responsedetail/25477
Spacetime should be retired but ripples in spacetime should remain  thanks to the ripples LIGO chieftains became millionaires. Steve Giddings concludes that it is worth living for ripples in spacetime:
"In celebration of Einstein's birthday, physicists reflect on the Germanborn scientist's work and its impact on the field and on everyday life. "We have good reason to believe general relativity is not a complete theory and, in particular, that it's going to break down in the context of describing black holes," said UCSB physics professor Steve Giddings. "That's very much an important problem in physics today. "The direct observation of gravitational waves from colliding black holes really constrains the possible departures from general relativity that we know are there and limits where modifications can be made," he continued. "But the discovery is still spectacular and its announcement was one of those moments in science that you live for." http://www.news.ucsb.edu/2016/016562/einsteinrevolution
