Lawrence M. Krauss, a theoretical physicist at Arizona State University, walked us through four of Einstein’s notable blunders.I am actually going to defend Einstein here. He was right that spooky action at a distance is unphysical.
1. Quantum Entanglement
Einstein referred to this physical phenomenon, which suggests that objects separated by great distances can affect one another, as “spooky action at a distance.” He rejected the possibility, refusing to believe that objects could influence each other no matter how far apart they were.
“He didn’t think the spooky action at a distance would be verified, but it was,” Dr. Krauss said. “He thought that was somehow unphysical. He presented this as an example of why quantum mechanics is probably wrong, but in fact it’s right.” ...
[another physicist said] “Now we have confirmed that there is spooky action at distance.”
The quantum mechanics experiments show that observing one electron can affect our best prediction for another electron. And they are consistent with observations making an instaneous effect to the wave function. But there is no proof that an action on one electron can have an immediate physical effect on a distant electron.
It is not that complicated.
People have their beliefs in reality or ontology of the wave function, parallel universes, ideal point particles, Bayesianism, and all sorts of other things. Depending on such beliefs, they may or may not believe in spookiness. But Krauss and the other physicist are dead wrong when they say that spooky action at a distance was confirmed. It has not. No Nobel prize has ever been given for it, and textbook quantum mechanics does not require it.
I look forward to the day when today's physicists are mocked for all their silly beliefs that were proved dead wrong. Spooky action at a distance. Many worlds interpretation. Supersymmetry. Unified field theory. Black hole firewalls. Proton decay. Magnetic monopoles. Quantum cryptography. Quantum computing. 10-dimensional strings. Black hole holographic universes. Boltzmann brains. Tegmark multiverses. Entropic gravity.
Krauss also has a NY Times article explaining LIGO:
Ultimately, by exploring processes near the event horizon, or by observing gravitational waves from the early universe, we may learn more about the beginning of the universe itself, or even the possible existence of other universes.See also Michio Kaku in the WSJ:
This may also have philosophical implications. Right now the big-bang theory doesn’t tell us what banged, why it banged, and what caused it to bang. It only tells us that there was a bang. But if space-based gravity-wave detectors similar to LIGO’s detectors can measure the radiation emitted an instant after the big bang, then, using mathematics, one can run the equations backward to determine what set off the big bang in the first place, in effect answering the biggest question of all: What banged and why?
