Michael Egnor to Jerry Coyne: Why the universe itself can’t be the most fundamental thing

Egnor: The cause of the universe must be something other than the universe itself and must have the power to cause things independently of the laws of nature. That is what all men call God. Read More ›

At Popular Mechanics: The universe is a “machine that keeps learning”

It sounds as though some would like to hold onto the name of Darwinism while — in reality — adopting panpsychism. That would be consistent with other trends we've noted. Read More ›

Is a new “muon” finding evidence for a fifth force of nature? Rob Sheldon weighs in

Sheldon: I hate to disappoint you, but most of my gut reaction is negative... In fact, this 40-year stasis in particle physics has meant that two generations of graduate students have never had a successful breakthrough experiment, or confirmed a new theory. The field, as Sabine Hossenfelder reminds everyone, is littered with wrong papers. Read More ›

Stan Robertson’s paper on black holes is free for download

One factor that one needn’t be a physicist to see is that black holes became a “thing” in popular culture, in a way that “red dwarfs” and “white dwarfs” never did. No one says that red dwarfs, for example, are a gateway to another universe. That sort of thing may affect people’s willingness to evaluate the evidence base critically. Cf Darwinism. Read More ›

Rob Sheldon takes aim at black holes: How much is really known?

It is most unfortunate that both scientists themselves and the popular press discuss black holes (bh) as if they are (a) a scientifically defined object; and, (b) an experimentally observed one. Read More ›

Sabine Hossenfelder asks, Should Stephen Hawking have won the Nobel? Rob Sheldon weighs in

Rob Sheldon: Hawking did not get the Nobel, however, because he hung his hopes on the radiation emitted by BH--the so-called "Hawking radiation". And it was never observed. Sabine tries to explain why. But one argument that Sabine doesn't make, is that Hawking radiation may never have been observed because BH are themselves never observed. Read More ›

Researchers: “Vast reservoir” of complex molecules found in cold cloud, not dying stars, as expected

Researcher: "It's like going into a boutique shop and just browsing the inventory on the front-end without ever knowing there was a back room. We've been collecting little molecules for 50 years or so and now we have discovered there's a back door. When we opened that door and looked in, we found this giant warehouse of molecules and chemistry that we did not expect," said McGuire. Read More ›

Sabine Hossenfelder reassures us that Schrodinger’s cat is still not dead

Hossenfelder: It’s no secret that I myself am signed up to superdeterminism, which means that the measurement outcome is partly determined by the measurement settings. In this case, the cat may start out in a superposition, but by the time you measure it, it has reached the state which you actually observe. So, there is no sudden collapse in superdeterminism, it’s a smooth, deterministic, and local process. Read More ›

Ethan Siegel: Failure to replicate a dark matter experiment is “an incredible success” for the scientific method

Siegel offers an inside look at the details. While the finding is doubtless a success for the scientific method, it must be frustrating for those physicists who need dark matter to exist in order to make cosmology understandable — but can’t find any. Read More ›

Sabine Hossenfelder explains why she thinks that the computer sim universe is pseudoscience

Hossenfelder: You can approximate the laws that we know with a computer simulation – we do this all the time – but if that was how nature actually worked, we could see the difference. Indeed, physicists have looked for signs that natural laws really proceed step by step, like in a computer code, but their search has come up empty handed. Read More ›

Rob Sheldon weighs in on the fundamental building blocks of nature – particles, fields, or …

Sheldon: It is curious that the author of this Aeon article has frozen Wheeler at his second stage, neglecting to mention his final conclusion. Read More ›
