Gr=Qm Newspaper Shows Susskind Isn't A Existent Co-Father Of Er=Epr

I conduct maintain e'er appreciated that inward comparing to other summit physicists, Leonard Susskind was amid those who deserved to last called heuristic thinkers, creative mavericks, talkers rather than calculators, in addition to to a large extent, I conduct maintain flora this spirit inspiring. Susskind was e'er a purpose model for me. The issue in addition to multifariousness of ideas he helped to emerge from the darkness was amazing.

Of course, equally the well-known lore says, physics depends on the fragile residuum betwixt the hot, bold, philosophical speculations on 1 side; in addition to the cold, hard, irksome facts on the other. When this residuum is broken, physics degenerates either to philosophy or to phytology (or postage stamp collecting). This lore is non meant to last an insult when it says that philosophy in addition to phytology are inferior because they self-evidently are inferior.

Well, the start outcome seems to last a proficient description of Susskind's novel paper

Dear Qubitzers, GR=QM

The 15-page newspaper is gratis of equations, begins amongst "Dear Qubitzers" (a hybrid of quantum flake in addition to kibitzers) in addition to ends amongst "Best regards, Lenny".




He says that non alone full general relativity in addition to quantum mechanics don't conduct maintain whatever tension. (They do. In the spacetime, they may last considered separately in addition to theories that observe both shape of principles are actually hugely constrained – to the extent that they must last string theory.) They are non alone compatible, Susskind's gospel continues. They are inseparable, they are the same thing. Some stories well-nigh wormholes are meant to back upward this arguing only they don't.

Susskind also says lots of his commons incorrect statements resulting from a deep misunderstanding of quantum mechanics – e.g. that "quantum mechanics is the same equally a classical simulation of it". H5N1 classical system, a simulation or otherwise, tin never last equivalent to a quantum mechanical theory. The old actually doesn't obey the doubt principle, allows objective facts; the latter requires an observer in addition to is a framework to calculate probabilities of statements that are alone meaningful relatively to a chosen observer's observations.




At the pop level, the proffer that "geometry in addition to quantum mechanics" may plough out to last the same thing inward the hereafter has been said for decades. For example, inward Brian Greene's The Elegant Universe which was published final century, Edward Witten in addition to Cumrun Vafa made similar comments during interviews mentioned inward the halt notes.

But inward the recent decade, physicists conduct maintain made progress beyond these vague statements. In particular, the ER-EPR correspondence is of import existent scientific discipline because it non alone emits these hippie qubitzers' statements of the type "all of us are brothers, all concepts inward scientific discipline are equivalent". It makes to a greater extent than precise statements that also include some "negative" implications.

For example, inward the basic ER-EPR correspondence, it's of import that the wormhole is non-traversable. An analogous equivalence arguing that would verbalize well-nigh traversable wormholes wouldn't last true. Generalizations are beingness constructed where a traversable wormhole is used on the GR side. But something analogous must last modified on the QM side, too.

Almost everyone knows that many insights inward the revolution involving entanglement inward quantum gravity has led us to recollect well-nigh basic quantum mechanics of elementary Hilbert spaces; in addition to physical systems involving dynamical curved infinite to last a duality of a sort, a duet of 2 "opposite" perspectives to await at the same thing.

But the devil is inward the details in addition to the devil matters. And the details, the devil, seems to last missing inward Susskind's letter.

So this alphabetic lineament that actually pays no attending to whatever of these details has reinforced my thought well-nigh the actual nativity of the ER-EPR correspondence. Juan Maldacena discovered it, went to Lenny, told him "don't yous desire to join? You've been proverb similar things" in addition to Lenny agreed because he flora the newspaper to last "in the correct direction". But all the actual function needed to verify that the structures on both sides jibe in addition to why they wouldn't jibe if something were dissimilar seem to last Juan's. Lenny seems to last confused – or enquiry – agency besides many things that are essential for these principles to work.

It seems clear to me that if alone Lenny were writing the ER-EPR paper, it would halt upward await similar this hippie qubitizers' letter. Even some 4 years later, he is notwithstanding at this unrefined level. I recollect that the cutting-edge enquiry is good ahead of these proclamations that resemble the dreams yesteryear the laymen who are high correct now. And brand no fault well-nigh it. Physicists inward California conduct maintain oft been high in addition to this field of the withdraw heed has been of import for sure enough of import papers yesteryear of import physicists to last written.

After all, if yous written report the community how it looked a few decades ago, yous volition uncovering amazing interactions betwixt Leonard Susskind in addition to e.g. Jack Sarfatti, a hardcore crackpot who believes to conduct maintain been abducted yesteryear extraterrestrial aliens, amid other things. This is Northern California. Everyone is high over there. But that's non quite plenty for progress inward physics. Thankfully, the globe has also had Argentina, the Garbage State some Princeton, in addition to other places.
