Sheldon: As a way out of this [origin of life] dilemma, many physicists reach into the religion bag and pull out spooky QM-at-a-distance. But it isn’t a solution, it is an admission of failure. For if they had reached a trifle deeper into the bag they would have pulled out Genesis 1. Instead, they have loosed this uncontrollable “dark matter”, “dark energy”, “dark QM” chaos god on the ordered universe of laws and purpose.
Sheldon: Actually the debate over “the meaning of QM” has been going on since 1935 when Einstein published his EPR paper. It is just that the wiggle-room is getting reduced as our straight-jacket is being cinched tighter.
Siegel: In other words, pretty much everything you’ve ever heard about Schrödinger’s cat is probably a myth, with the sole exception of the fact that quantum systems actually are well-described by a probabilistically weighted superposition of all possible, allowable states, and that an observation or measurement will always reveal one and only one definitive state.
Involving quantum mechanics: In an enormously complicated 165-page paper, computer scientist Zhengfeng Ji and colleagues present a result that penetrates to the heart of deep questions about math, computing and their connection to reality. It’s about a procedure for verifying the solutions to very complex mathematical propositions, even some that are believed to be impossible Read More…
QM is all about microstates and their measurement, but not about macroscopic properties that you and I normally associate with everyday objects–smoothness, ripeness, tools like “hammer and nail” or biology like “chicken and egg”. So indeed we can entangle QM microstates, but can’t entangle chickens and eggs, and therefore using those terms creates a semantic muddle.
He argues that a recent study shows that not only can two physically separated particles influence each other, they can influence each other through time and that it identifies a Mind behind the universe.
Because quantum mechanics “lacks a physical description of the measurement process. The open-access paper seems easy to read.
Wouldn’t making free, legal pot available accomplish the same intellectual goal?
Sheldon: “By measuring a hot stream of molecules with billions of states, this experiment may rule out CSL [Continuous Spontaneous Localization]. If so, it would be the first time an interpretation of QM was actually invalidated, suggesting we have entered a new era of testing theories of the foundations of QM.”
Demonstrated with a molecule of 2000 atoms.
Researcher: The electron not only receives the expected momentum, but additionally one third of the photon momentum that actually should have gone to the atom nucleus. The sail, (electron), of the boat, (nucleus), therefore “knows” of the impending accident, (collision from the photon), before the cords tear and steals a bit of the boat’s (nucleus’s) momentum.
Carroll wants a multiverse out of any new findings, one suspects. One question many might have is, apart from the lack of a multiverse, how bad is the current situation in physics? What, besides that, is going wrong?
Hossenfelder: “Now, a lot of people discard superdeterminism simply because they prefer to believe in free will, which is where I think the biggest resistance to superdeterminism comes from.”
Wait a minute! Wasn’t there cosmic Darwinism a decade ago? Yes, here. And quantum Darwinism whistled through in 2016 too.
His view: What this recent paper with a qutrit experiment shows, is that it is possible to do QM communication or QM computing at high volume and high speed. No need to wear headphones. Our view of the universe has not changed.
