Science writers, and their readers, often seek a certainty from science that it can’t really provide. They graft it in — so, of COURSE, they find it.
And ends by saying that childhood genetic engineering will probably bring an end to high achiever sports altogether.
Hossenfelder: “… the chaotic motion of Hyperion tells us that we need the measurement collapse to actually be a physical process. Without it, quantum mechanics just doesn’t correctly describe our observations. But then what is this process? No one knows. And that’s the problem with quantum mechanics.”
Hossenfelder: Is it correct? I don’t know. It could be. But in all honesty, I am very skeptical that this result will hold up. More likely, they have underestimated the error and their result is actually compatible with the other measurements.
Hossenfelder: But this illusion of progress is the minor problem. Worse is that they seem resigned to the idea that foundational work in physics is detached from experiment and technological application.
Biophysicist Kirk Durston offers some feedback to theoretical physicist Sabine Hossenfelder. Lots of comments, including “You are dead on that she avoids talking about how space, time, matter, and energy came into existence.”
Horgan sides, somewhat tentatively, with free will. He notes that humans are more than just heaps of particles. Higher levels of complexity enable genuinely new qualities. What humans can do is not merely a more complex version of what amoebas can do — in turn, a more complex version of what electrons can do. Greater complexity can involve genuinely new qualities. A philosopher would say that he is not a reductionist.
The usually commonsensical Sabine Hossenfelder admits that this one stumps physicists: Well-attested observations of neutrinos are not compatible with the Standard Model of our universe that most physicists accept. Much about neutrinos is weird and it does not appear to be an artifact of bungled experiments.
Hossenfelder: Together the two men discovered 136 species of dinosaurs (Cope 56 and Marsh 80) but they died financially ruined with their scientific reputation destroyed [over their feuds].
Hossenfelder: What you can see from this graph is that if this theory is correct there basically shouldn’t be any large galaxies at very early times… If the Webb telescope sees large galaxies anyhow, then that’s going to be very difficult to explain with dark matter.
Hossenfelder: “[O]nce you insist that the ratio was actually one, you have to come up with a mechanism for how it ended up not being one. And then you can publish papers with all kinds of complicated solutions to the problem which you just created. ” Isn’t she overlooking something?
Hossenfelder: Inside a neutron and proton there aren’t just three quarks. There’s really a soup of particles that holds the quarks together, and some of the particles in the soup are anti-particles. Why don’t those anti-particles annihilate? They do. They are created and annihilate all the time. We therefore call them “virtual particles.” But they still make a substantial contribution to the gravitational mass of neutrons and protons.
Sabine Hossenfelder admits that “The problem has kept her up at night for decades, she says, and it appears we are no closer to an answer”
The difficulties inherent in the idea of terraforming Mars are a good argument for the Privileged Planet Hypothesis regarding Earth. Earth is indeed special.
Sheldon: Even though I agree with Sabine about the fine tuning argument, I disagree strongly with her about the significance of the design we see in the world. “It just is” is not an explanation.
