Well, they do seem to be taking it seriously.

Sabine Hossenfelder dusts off “superdeterminism”
Hossenfelder: “Now, a lot of people discard superdeterminism simply because they prefer to believe in free will, which is where I think the biggest resistance to superdeterminism comes from.”
We are told that quantum Darwinism has passed its first test
Wait a minute! Wasn’t there cosmic Darwinism a decade ago? Yes, here. And quantum Darwinism whistled through in 2016 too.
New Scientist welcomes us to the fifth dimension
In pop science media, the End of All Things is the heat death of the universe, but some opt for stranger fates instead.
Rob Sheldon: What to do now in particle physics
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.
Rob Sheldon on celeb physicists Sabine Hossenfelder, Ethan Siegel, and Chad Orzel
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.
Particle physics is a mess but Hossenfelder should chill, fellow physicist says
Hmmm. He’s not giving fellow physicists much of an incentive to sort out the mess. On the other hand, civilized theoretical physicists fight so politely that you can learn a lot just by listening.
Ethan Siegel: Don’t trust experiments that claim there are parallel universes
This sounds so sensible, we thought theoretical physicist Sabine Hossenfelder would say it. But astrophysicist Ethan Siegel said it. A sober position for him.
New measurement keeps the discrepancy around the Hubble constant alive
So if there is something fundamentally wrong with our picture of the universe, there still is, more or less, and we will have to live with it for now.
A black hole that just shouldn’t exist
Researcher: “We cannot understand the data unless we include the theories of relativity.” …
New Scientist: Our understanding of the cosmos is “seriously wrong”
But don’t fret that a better understanding of the universe will leave entertaining crackpots out in the cold. Won’t happen. Can’t. Ethan Siegel explains why, in part.
Could “quasiparticles” reveal dark matter?
One group of physicists proposes an experiment to try to trick dark matter into revealing itself, involving a unit of energy called a “magnon.”
Computer sim universe: An escape from the facts of fine-tuning?
Walter Bradley Center fellows weigh in: The idea that we are a simulation by space aliens is a staple of science fiction, of course (think The Matrix, 1999). But some scientists take this simulation hypothesis seriously. Serious discussion started with a paper by philosopher Nick Bostrom in 2003, “Are you living in a computer simulation?” […]
The multiverse is just religion, theoretical physicist charges
Of course she’s right about the religion part. Much that is going wrong with science today is the tendency to use various science ideas as secular religions. The multiverse happens to be a particularly devastating one because it strikes at the very idea of evidence.
Why should science need evidence anyway? Why isn’t speculation good enough?
Reviewer Kumar’s thought seems to be, as long as the speculation is rooted in the two great theories, it’s science. A need for evidence is an unreasonable burden.
