Hossenfelder: What we have here in the foundation of physics is a plain failure of the scientific method. All these wrong predictions should have taught physicists that just because they can write down equations for something does not mean this math is a scientifically promising hypothesis.

Jerry Coyne berates panpsychists and tackles the hard problem of consciousness
So did Coyne not give Goff the right of reply? Apparently, he would need a beaker of antacid to read the guy’s book…
Listen to Mother Nature Network convince itself that parallel worlds exist
Nope. Not a chance the proposed evidence will matter. The parallel universe folk probably don’t like our universe because it shows massive evidence of fine-tuning and that implies an intelligent origin. Any alternative theory will always be popular, irrespective of evidence.
We are told that researchers found the universe’s “first molecule” in 2019
Last April Astronomers finally detected some helium hydride in a gas cloud about 2900 light years from Earth.
At PhysicsWorld: Image of black hole and its shadow is the breakthrough of the year
The image is thought to establish that black holes really do exist; they are not just astrophysicists’ imaginings.
Sabine Hossenfelder proposes superdeterminism” to replace quantum mechanics
Because quantum mechanics “lacks a physical description of the measurement process. The open-access paper seems easy to read.
People want time travel and they don’t care what they have to believe to get it
New Scientist suggests that split parallel universes would avoid the problem of messing with the past so that you don’t exist.
Has another hole been found in the standard model of the universe?
How about?: The Standard Model is terrible—until you compare it to string theory and the multiverse
A glimpse at one facet of post-science physics
In the post-science world, people can presumably define success according to their own frames of reference, in relation to their own facts and their own truths.
Physicist spars with science writer over whether the laws of physics are inevitable
Of course, neither Wolchover nor Hossenfelder would be allowed to notice that design in nature is obvious but not inevitable.
But then again, maybe time is all in our heads?
If time were really all in our heads, we would never miss planes. Good thing modern cosmology does not need to be serious.
Ethan Siegel’s claim at Forbes: Why we’ll never exactly solve general relativity. Rob Sheldon responds
Not only is Ethan’s profession about to get a major readjustment, but his attitude needs a readjustment as well. No longer can he and his colleagues hide in their ivory tower telling the world that we must leave the hard thinking to them. As many have already commented, the woke mobs are already at the gates.
Researchers: No, you can’t escape a black hole
Why not?: “The group found that for both types of black holes they examined, there is indeed a central singularity, and it is always spacelike. “
So then maybe we ARE privileged observers
Researcher: “Our analysis is data-driven but supports the theoretical proposal due to Christos Tsagas (University of Thessaloniki) that acceleration may be inferred when we are not Copernican observers, as is usually assumed, but are embedded in a local bulk flow shared by nearby galaxies, as is, indeed, observed. This is unexpected in the standard cosmological model, and the reason for such a flow remains unexplained.
John Horgan on how multiverse theories are bad for science
The Scientific American columnist is unimpressed by two recent books on the subject, cosmologist Sean Carroll’s Something Deeply Hidden and science writer Tom Siegfried’s The Number of the Heavens.
