...hast Du eine Kernaussage von Lubos gefunden, Zara.

Aha:

Sorry, Einstein. Quantum Study Suggests ‘Spooky Action’ Is Real.

No, there is no "spooky action". The two measurements are correlated
because of the contact of the two particles in the past, because of events
in the intersection of the two particles' past light cones, because of the
"origin" that both particles share. The correlations do not arise from any
action or any influence at the moment of the measurement. What is observed
is correlation (between A and B) but correlation doesn't imply a causation
(A's influence on B or B's influence on A). Instead, the correlation is
explained by the initial state of both particles, C, that has influenced
the results of measurements of A as well as B.

Einstein chose the term "spooky action" in order to suggest that quantum
mechanics predicts something illegitimate – and the action at a distance
would certainly be illegitimate because it would conflict with relativity.
However, Einstein's argument was just wrong. Quantum mechanics doesn't need
any action to guarantee the correlations that follow from entanglement. It
doesn't transfer any transformation superluminally. Never. Ever. Quantum
mechanics doesn't necessitate any contradiction with relativity and quantum
field theories are 100% exactly compatible both with special relativity and
with the postulates of quantum mechanics.

Seine Erklärung scheint etwas Drittes zwischen dem üblichen "it's either Spooky Action or Hidden Variables, stupid!" zu implizieren. Was genau das ist, scheint aber auch innerhalb der Wissenschaftsgemeinde fast nur ihm selber und seinem Kollegen Maldacena so richtig klar zu sein -- auch nach LuboÅ¡' Totalverriss der jeweils aktuellsten, offiziellen 'Quantenfernwirkungs'-Experimente zu urteilen.

Stringtheorie-Genies unter sich halt 🤷

Luboš:
• Einstein has influenced me tremendously when I was a teenager
• When I was 10 or so, I had some alternative version of special relativity
• I understood the actual special relativity a year later
• When I was 14, I got extremely excited by the idea that all elementary particles were "wormholes of different topologies"

Viele Grüße
Kurt
