Sabine Hossenfelder: Is math real?

Denyse O'Leary
July 31, 2021
Intelligent Design, Mathematics, Philosophy
Hossenfelder: The physicists who believe in this argue that unobservable universes are real because they are in their math. But just because you have math for something doesn’t mean it’s real. You can just assume it’s real, but this is unnecessary to describe what we observe and therefore unscientific. Read More ›

Sabine Hossenfelder’s op-ed not published at APS?

Denyse O'Leary

Intelligent Design, Multiverse, Philosophy, Science
This is the kind of thing she said: What about Avi Loeb’s claim that the interstellar object `Oumuamua was alien technology? Loeb has justified his speculation by pointing towards scientists who ponder multiverses and extra dimensions. He seems to think his argument is similar. But Loeb’s argument isn’t degenerative science. It's just bad science. He jumped to conclusions from incomplete data. Read More ›

Exotic particles that don't survive a news cycle. She shows how they’re artifacts of the fact that very large numbers often show what appear to be patterns but are just noise. Read More ›

How Sabine Hossenfelder’s opinion of dark matter has changed over 20 years

Denyse O'Leary

Cosmology, Intelligent Design, Physics
She thinks the solution now is to combine dark matter with modified gravity. Now that will be a challenge. We kind of wish she would go back to denying free will and fine-tuning of the universe. Read More ›

Sabine Hossenfelder: Does the universe have higher dimensions?

Denyse O'Leary
April 18, 2021
Cosmology, Intelligent Design, Physics
Hossenfelder: If one adds 7 dimensions of space to our normal three dimensions, then one can describe all of the fundamental forces of nature geometrically. And that sounds like a really promising idea for a unified theory of physics. Indeed, in the early 1980s, the string theorist Edward Witten thought it was intriguing that seven additional dimensions of space is also the maximum for supergravity. However, that numerical coincidence turned out to not lead anywhere. This geometric construction of fundamental forces which is called Kaluza-Klein theory, suffers from several problems that no one has managed to solved. Read More ›

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

Cosmology, Intelligent Design, Physics
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 ›

Sabine Hossenfelder asks: Whatever happened to life on Venus?

Extraterrestrial life, Intelligent Design
Hossenfelder ends by reminding us, re phosphine on Venus, that “ absence of evidence is not evidence of absence.” True, but that’s just a corollary of the fact that one can’t prove a negative. No, we can’t but that doesn’t prevent us from drawing reasonable conclusions. The proverb has been used to cover far too many situations where a more realistic conclusion would be “There is no particular reason to believe this.” Read More ›

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

Cosmology, Intelligent Design, Physics
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 ›

Sabine Hossenfelder asks, Do complex numbers exist?

Denyse O'Leary
March 6, 2021
Intelligent Design, Mathematics
The people who don’t think complex numbers really exist would probably not be happy with quantum mechanics being even more non-local without them. But of course, if complex numbers really do exist, then immaterial things really exist. Not a good time to be a hard core materialist. 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 ›
