I’m heading into a studio next week to record the audio version of my new book ‘Discordance: The Troubled History of the Hubble Constant’. This will be a new experience for me. Anyone have any tips?

Nostalgia attack! I remember reading this as a young kid (about 8 years old). It featured Fireball XL-5 and Stingray and a cartoon strip featuring Lady Penelope. When a reader wrote in to ask who she was, the editor explained that she was a character in a new show called Thunderbirds, which …

Anyone watching the reactions to the murder of Charlie Kirk might want to Google ‘Horst Wessel’.

The Big Bang - is it a theory in crisis? @jimbaggott.bsky.social @aeon.co ‬⁩ aeon.co/essays/why-m...

What's up with the Big Bang theory? aeon.co/essays/why-m...

Although it tells a remarkable story, the current Big Bang theory leaves us with many unanswered questions, and recent astronomical observations threaten to undermine it completely. @jimbaggott.bsky.social

The Large Hadron Collider beauty (LHCb) collaboration at CERN has made the first observation of asymmetry in the decay rate of a baryon—a subatomic particle made of three quarks—and that of its antibaryon counterpart. It partly explains why there is matter in the universe.

Fifty years ago today, I was heading home from the Reading Rock Festival. Here’s what I remember … open.substack.com/pub/jimbaggo...

Remembering the Reading Rock Festival 1975. I vaguely recall being there. Just posted earlier today. open.substack.com/pub/jimbaggo...

I kind of understand the sentiment, but as a long-standing West Brom fan (more follower now) I must say the thought of having to watch my team get utterly thrashed four times a season does not thrill me. That’s a cruel and unusual punishment. 🫣

For all the prog rock afficionados out there.

RIP Allan Ahlberg, who helped transform reading to young children into an enormous pleasure. Burglar Bill and Funnybones are still favourites, recently bought for my grandchildren. www.theguardian.com/books/2025/j...

Hello. I’m a quantum physicist in a film. I spend all my time travelling (through time) and exploring the multiverse to investigate the Deutsch proposition. My laboratory is full of expensive lasers and I have a smug, knowing smile forever fixed on my face. I have a cat called Schrodinger.

I lose a little bit more brain matter every time I listen to this. Thanks @markburgessosl.bsky.social Senri Kawaguchi demonstrates that awesome prog rock drumming is about speed and precision, not power.

This Aeon piece by @jimbaggott.bsky.social, one of our best science writers, is by far the clearest explanation of the Schrodinger's cat thought experiment I have seen. It raises many of the fundamental questions in physics. At the end, #Baggott answers some very interesting questions from readers.

How did an obscure argument about a complex theory of physics become embedded in public consciousness as an extraordinary exploration of the human psyche? This essay tells the story @jimbaggott.bsky.social buff.ly/TYwKe9Z

This was one of my most popular essays on Substack. Re-written for the popular online philosophy magazine Aeon. Enjoy! And if you’re curious please be sure to post a comment/question.

I first saw Alien at the cinema in Oxford in 1979. I hadn’t known of HR Giger’s involvement, but,like any fan of Emerson, Lake & Palmer, recognised his work instantly from the cover art of 1973’s Brain Salad Surgery.

All very commendable. But if you’re going to teach kids how to distinguish truth from falsity, you need also to teach something of the philosophy of truth. When does conspiracy theory morph into (religious) faith? How do you deny people from from believing what they want to believe?

I’m not convinced. www.bbc.co.uk/news/article...

‘Promising’ is doing a *lot* of heavy lifting here. The article is quite well balanced, but in our hyper-distracted social media age, I fear few will take the trouble to get beyond the headline. Telescope finds promising hints of life on distant planet www.bbc.com/news/article...

So, Jim. What do you do in your spare time? Well. I enjoy writing individually worthless books used as free content to train LLMs. What do you do?

Taking disciplinary action againt Musk would be ‘damaging to the society and to science itself’. Utterly wrong. More damage is being done by refusing to acknowledge the harm this idiot is causing. www.theguardian.com/technology/2...

If, like me, you’re weary of the endless stupidity and awfulness of the Trump White House, and utterly baffled by Starmer’s red lines, here’s a clip from a time when there seemed more joy and hope in the world. Enjoy. youtu.be/iRSktm7GCmk?...

Thanks Andy, much appreciated.
