With respect to the simulation multiverse: Why could there not be countless, helplessly infinite, simulations of the simulations as well?
Tag: Sabine Hossenfelder
What does it mean to say, in physics, that something like the Higgs boson “exists”?
Sabine Hossenfelder’s view: Realism is a philosophy. It’s a belief system, and science does not tell you whether it is correct.
Sabine Hossenfelder: Black holes vs. quantum mechanics = something has to give
Her view: Most physicists believe that the solution is that the Hawking radiation somehow must contain information after all.
When particle physicists collide, some are transformed into children
My, my. A commenter formed the correct impression and suggests, “Could you please answer the very valid questions raised by Sabine [Hossenfelder] instead of smearing her like this?”
Sabine Hossenfelder: “We know that quantum mechanics is wrong.”
Do we know that quantum mechanics is wrong and, if so, how can it be useful?
Neurosurgeon Michael Egnor: Physicist Sabine Hossenfelder is really confused about free will
It really is quite funny. And physicists should stick to physics.
Sabine Hossenfelder on the flight from falsifiability
Hossenfelder is right to be concerned. Some cosmologists would like to dump falsifiability as a criterion. If they could, they would remove an obstacle to demanding public belief in ideas like the multiverse, ideas that cannot be falsified because there is no evidence for them.
Do science hero stories stand in the way of progress?
Sabine Hossenfelder thinks that in fundamental physics the problem is not a shortage of smart people but a shortage of smart people who grasp that they are simply “wheels in the machinery.”
Have quantum physics’ problems been disgracefully swept under the carpet?
Possibly, but maybe it’s inherently fuzzy. Meanwhile, an update on Adam Becker’s attack on Inference Review as an ID-friendly rag; Peter Woit and Sabine Hossenfelder weigh in.
Sabine Hossenfelder: Has the Large Hadron Collider “broken physics”?
Question: Who decided that physics had to be “natural”? What does that mean? And what if “naturalness” is not an attribute of the physics of our universe? What does that mean?
Sabine Hossenfelder: Can gravitational wave interferometers tell us if we live in a hologram universe?
It’s actually a good thing if theses in physics don’t gain currency just because they make good TED talks. That could be part of theirproblem.
Hugh Ross: The fine-tuning that enabled our life-friendly moon creates discomfort
Astronomer Robin Canup has spent fifteen years developing models that seem to demonstrate that, whether it is a desired finding or not: Such fine-tuning was not lost on Canup, who remarked in a recent Nature review article, “Current theories on the formation of the Moon owe too much to cosmic coincidences.”4 Indeed, the required “coincidences” […]
Sabine Hossenfelder: Is science harmed by an illusion of progress?
Tellingly, Hossenfelder adds, “So here is the puzzle: Why can you not find any expert, besides me, willing to publicly voice criticism on particle physics? Hint: It’s not because there is nothing to criticize. ”
Dark matter vs. dark energy in a world where neither have been discovered
Hossenfelder’s clarifications will at least help us understand what we are all confused about.
Theoretical Physicist weary of people telling her 2+2 = 5
No, Sabine, you’re not crazy. But you live in crazymaking times. Cosmology has degenerated into the pursuit of cool nonsense like the multiverse via string theory. So much now seems to revolve around whether findings help or hurt the nonsense. Not about learning more about what is really happening here now.
