Spending the day at the UK Cosmo meeting here at Imperial College, with excellent talks by young cosmologists from around the country. We’ll also be taking the opportunity to remember the great Tom Kibble, one of the founders of cosmology here at Imperial and throughout the UK (and the world). https://indico.global/event/15684/
UK Cosmology Meeting

The next UK Cosmology Meeting will take place at Imperial College London on March 25th 2026. [Registration is closed]. This one-day event aims to bring together the whole cosmology community in the UK to discuss recent trends in theoretical and observational cosmology. We will have several talks by young researchers and PhD students in the field, a plenary talk by Danièle A. Steer (LPENS and Université Paris Cité), and a poster session. Please feel free to email us if you have any questions.

Just recorded a segment on probability, randomness, cosmology and The Random Universe for “The Science Show” with Richard Marshall on Resonance FM. It will be broadcast at 3pm on Monday 6 April (and available on MixCloud from then on…). https://www.resonancefm.com
Resonance FM | Home

Resonance is a groundbreaking 24/7 radio station which broadcasts on 104.4 FM to central London, DAB to Greater London, nationally on Radioplayer and live streamed to the rest of the world

Most ideas that disagree with the dominant scientific paradigm in any field are certainly wrong — even though the dominant paradigm is probably also wrong.

In honor of the coming vernal equinox, my first cycle ride into work since October.
Thanks to Richard Marshall — and a fantastic audience, especially! — for a great evening of cosmology, cosmological tensions, and beer @pubsci.bsky.social.
Off to The Old King’s Head for some cosmology. https://pubsci-march2026.eventbrite.co.uk/
Last day of regular teaching for the academic year — two hours of tutorials and the final lecture of my cosmology course (for the aficionados, we will be working toward the processed power spectrum of density perturbations).
Talking about The Random Universe and cosmological controversies at PubSci — Wednesday at the Old King’s Head near Borough Market in London. Come enjoy the beverages of your choice with some cutting edge science! (Latest — sold out! But you can join the waitlist.) https://www.ianvisits.co.uk/calendar/is-everything-we-know-about-the-big-bang-wrong-with-andrew-jaffe-428686/
Is Everything we know about the Big Bang wrong? with Andrew Jaffe

This month an award-winning astrophysicist looks at how understanding uncertainty and randomness has led to breakthroughs in our knowledge of the cosmos but also challenges what we thought we knew.
