Nima Arkani-Hamed: The Doom of Spacetime

Friday, December 1, 2017: The Doom of Spacetime - Why It Must Dissolve Into More Fundamental Structures. Nima Arkani-Hamed, Professor, The Institute for Advanced Study, Princeton, and A. D. White Professor-at-Large, Cornell University https://www.meetup.com/philsoc/events/244673165/

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

That's great, breathtaking, but the nonexistent spacetime is a consequence of Einstein's constant-speed-of-light postulate:

"Special relativity is based on the observation that the speed of light is always the same, independently of who measures it, or how fast the source of the light is moving with respect to the observer. Einstein demonstrated that as an immediate consequence, space and time can no longer be independent, but should rather be considered a new joint entity called "spacetime." http://community.bowdoin.edu/news/20...rs-of-gravity/

Logic forbids the combination

"true postulate, nonexistent consequence"

so Nima Arkani-Hamed will have to conclude that Einstein's constant-speed-of-light postulate is false.

Another problem. There are ripples in the nonexistent spacetime gloriously discovered by LIGO conspirators. Nima Arkani-Hamed will have to declare that LIGO conspirators are fraudsters and face the retaliation of LIGO godfathers.

Up until recently string theorists were the most powerful businessmen in physics - so powerful that their bosses felt safe to go as far as this:

Nobel Laureate David Gross observed, "Everyone in string theory is convinced...that spacetime is doomed. But we don't know what it's replaced by." https://www.edge.org/response-detail/26563

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..." https://www.edge.org/response-detail/25477

"Rethinking Einstein: The end of space-time. It was a speech that changed the way we think of space and time. The year was 1908, and the German mathematician Hermann Minkowski had been trying to make sense of Albert Einstein's hot new idea - what we now know as special relativity - describing how things shrink as they move faster and time becomes distorted. "Henceforth space by itself and time by itself are doomed to fade into the mere shadows," Minkowski proclaimed, "and only a union of the two will preserve an independent reality." And so space-time - the malleable fabric whose geometry can be changed by the gravity of stars, planets and matter - was born. It is a concept that has served us well, but if physicist Petr Horava is right, it may be no more than a mirage. Horava, who is at the University of California, Berkeley, wants to rip this fabric apart and set time and space free from one another in order to come up with a unified theory that reconciles the disparate worlds of quantum mechanics and gravity - one the most pressing challenges to modern physics." https://www.newscientist.com/article...of-space-time/

Then LIGO conspirators came to power and string businessmen had to declare allegiance to the new godfathers. David Gross and Steve Giddings did it immediately - spacetime is not doomed anymore and the undulations of spacetime are worth living for:

"Detection of the gravitational wave signal, resulting from the merger of two black holes, was the culmination of more than four decades of effort by researchers with funding from the U.S. National Science Foundation. "This is a marvelous prize that recognizes the heroic and successful detection of the undulations of spacetime predicted over a hundred years ago by Albert Einstein," said David Gross, winner of the 2004 Nobel Prize in Physics and Vice President of APS. "By using gravitational wave detectors, LIGO has created a new window to probe the universe." https://www.aps.org/publications/aps...es/nobel17.cfm

"In celebration of Einstein's birthday, physicists reflect on the German-born 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...ein-revolution

Only Petr Horava went into hiding and has not yet decided how to react:
