Physicist: The ultimate theory will be “geometrically natural”

At her blog, Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray, offers a guest post spot to a fellow physicist: No current unified theory includes quantum mechanics fundamentally as part of its structure. But a truly unified theory must. And I believe the ultimate theory will be geometrically natural. Canonical quantum commutation […]

Theoretical physicist: Present phase of physics “not normal” – but stagnation, not crisis

Theoretical physicist Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray, acknowledges the seriousness of the situation but isn’t sure that the term “crisis” describes the current situation well: I think stagnation describes it better. And let me be clear that the problem with this stagnation is not with the experiments. The problem […]

Theoretical physicist Sabine Hossenfelder shares her self-doubts about exposing nonsense in cosmology

One must hope that Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray, isn’t too worried about the people who criticize her: Let us leave aside for a moment that you have to skip half the book to not notice I question myself on every other page. Heck, if you ask me to […]

Black holes do not behave as string theorists say they should

Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray, explains, Three weeks ago, Steinhauer’s group reported results from a new experiment in which they have now measured the temperature of the fluid black hole: Observation of thermal Hawking radiation at the Hawking temperature in an analogue black hole Juan Ramón Muñoz de Nova, Katrine […]

“Perhaps physics has slipped into a post-empirical era…”

Science writer David Appell suggests this, in all seriousness, in his review of Sabine Hossenfelder’s Lost in Math: How Beauty Leads Physics Astray, at Physics World: Hossenfelder confronts physicists to ask them why their ideas aren’t working. Michael Krämer, who heads the new-physics group at the LHC and works on supersymmetry, tells her that he is “honestly […]

The fight over the universe has turned ugly, with accusations of “cheating”

We are told: “Wherever you look in the cosmos, things don’t seem to add up.” And now physicists like Sabine Hossenfelder are accused of cheating: Ethan Siegel, astrophysicist-blogger behind Forbes’ Starts With a Bang! blog, responded with a post titled “There’s A Debate Raging Over Whether Dark Matter Is Real, But One Side Is Cheating.” […]

How Roger Penrose proposes that the universe can be eternal

For all practical purposes. From the author of Lost in Math: How Beauty Leads Physics Astray, at her blog BackRe(Action) According to Penrose’s conformal cyclic cosmology, the universe goes through an infinite series of “aeons,” each of which starts with a phase resembling a big bang, then forming galactic structures as usual, then cooling down as […]

Reader asks physicist: Is there a universe in every particle?

The physicist who answers is Sabine Hossenfelder, author of Lost in Math: How Beauty Leads Physics Astray (2018) and she responds, saying (among other things) If you want every elementary particle to each have a universe inside, you need to explain why we only know 25 different elementary particles. Why aren’t there billions of them? An […]
