Sheldon: It was Chesterton who said, “He who marries the culture will soon be a widower.”
Levin: When the Viking Molecular Analysis Experiment failed to detect organic matter, the essence of life, however, NASA concluded that the LR had found a substance mimicking life, but not life. Inexplicably, over the 43 years since Viking, none of NASA’s subsequent Mars landers has carried a life detection instrument to follow up on these exciting results.
“Let me repeat. Physics doesn’t change. And even when discussing the changes (like an oscillation), the physics of change doesn’t change. Somebody is making a serious category error when the physics of change becomes the change of physics.”
Rob Sheldon: Despite McMaster U. thinking this odd, and believing (hoping?) for a failure of the Standard Model, I see this as a necessary means of storing the information in the hot Big Bang, and demonstrating the ultimate fine-tuning of the cosmos.
Sheldon: My best guess is that he has found something organically simple such as polycyclic aromatic hydrocarbons (PAH), if only because 3.5 billion years is a long time for organics to survive, and PAHs are the sort of keratonized (turned into keragen) that is stable.
Sheldon: … it isn’t just HEP theory, it is large swathes of all the sciences. They have painted themselves into a sterile, but formerly well-funded “consensus” corner, and are discovering that the younger generation (and the NYT) is quite flippant on their prospects for survival.
“Most, if not all the hype you read, is looking for more and more exotic particles, all the while ignoring mundane macroscopic things like comets and asteroids.”
The panic in sociology, psychology, nutrition science, and pharmacology has been growing as >70% papers with “p-values” smaller than 0.05 are discovered to be unrepeatable.
Sheldon: … in our own solar system, Saturn is far outside the “Goldilocks Zone” yet it has a moon, Enceladus, that is emitting steam jets filled with hydrocarbons. … The danger of being overly-quantitative is not just the overreliance on models, or the higher risk of failure, but rather the real probability that “certainty” blinds one from observing the actual phenomenon.
Rob Sheldon: What is really recycling is not the universe, but this theory.
The theory has been resurrected in a paper in PNAS, of which Rob Sheldon says, “None of these steps is remotely likely. Not one.”
Forget “new physics”. Forget the Nobel Prize. Get some humility, especially us physicists, and realize that everything we possess is a gift. Show some gratitude by filling in one of the many textbook gaps.
My own view is that we need to go back to 1950 and revisit the alternatives. Because solving today’s impasse doesn’t require any new physics, but old physics done differently.
In an infinite universe, somebody somewhere has figured out how to talk from one universe to another. In an infinite universe, somebody somewhere has figured out how to talk from one universe to another.
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.
