Hossenfelder: … what if you could experience quantum effects. Not in the real world, but at least in a virtual world, in a computer game?
Marcelo Gleiser dismisses the notion for physics reasons but he also objects to the way it casts doubt on free will, which we need to tackle our problems.
Takehome: Neurosurgeon Michael Egnor points out that, though free will may be unpopular with atheist thinkers like biologist Darwinian evolutionary biologist Jerry Coyne, science doesn’t refute it.
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.”
The worldview in which Darwinism made sense will not survive quantum mechanics.
She argues that the principle of least action is the closest we have to a theory of everything but, of course, along comes quantum mechanics and… Quantum mechanics keeps the world interesting and reminds us that this is not a deterministic world after all.
If the scenario really violates the Law of Conservation of Energy, all bets are likely off about evolution issues of any type. Most likely, though, there is another explanation.
Annaka Harris: “I think the flow of time is not part of the fundamental structure of reality,” theoretical physicist Carlo Rovelli tells me. He is currently working on a theory of quantum gravity in which the variable of time plays no part.”
Researchers: “A single neutron is measured at a specific position—and due to the sophisticated measurement setup, this single measurement proofs already that the particle moved along two different paths at the same time. It is even possible to determine the ratio in which the neutron was distributed between the two paths. Thus, the phenomenon of quantum superposition can be proven without having to resort to statistical arguments.” Albert, check your mail.
Hedin: Life with its “radiant beauty” defies naturalistic explanations.
It seems helpful to illustrate cosmological scale apparent aging as stars depart main sequence: An idealised, Hertzsprung-Russell chart for Hydrogen-rich balls prone to become fusion furnaces is: Here is a comparative plot (for open clusters), constructing a “clock” by projected pattern as a cluster ages, in effect seeing what is left as a candle burns Read More…
Philosopher Sam Baron: So unless we can come up with a good account of how time emerges, it is not clear we can simply assume time exists.
Snoke: I argue that information and entropy are objective physical quantities, defined for systems as a whole, which allow general arguments in terms of physical law. In particular, I argue that living systems obey the same rules as Maxwell’s demons.
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.
Rob Sheldon notes that the more real-world information we have, the less the bits weigh until, at very large amounts of information, they weigh almost nothing.
