Is Cosmology in Crisis? Public talk on the 8th September: more info here:https://sites.google.com/cam.ac.uk/kas2026/public-talk?authuser=0

How well do we really understand the Universe?

95% of it — dark matter and dark energy — remains fundamentally unexplained, and a growing set of tensions in the data is prompting a serious question: is our standard model of cosmology beginning to break?

The Kavli Institute for Cosmology, Cambridge is delighted to host a public discussion with three world-leading cosmologists — Prof. George Efstathiou, Prof. Wendy Freedman, and Prof. Risa Wechsler — exploring the cutting-edge surveys that could resolve these puzzles, or deepen them.

📅 Tuesday 8 September 2026, 6–7pm
📍 Ray Dolby Centre, Cambridge
Free to attend. Booking via Eventbrite:

Our 1909 Professor Hiranya Peiris brilliantly explains in Nature why the proposed cuts to particle physics and astronomy will be so damaging:

Restructuring research funding as a choice between discovery and application gets the economics wrong, the evidence wrong and the people wrong.

IoA researchers have produced the most detailed study yet of the four planets orbiting Barnard's Star — our Sun's nearest neighbour after Alpha Centauri — finding them to be tidally locked, and rich in a mineral that makes them poor at retaining water, rendering them utterly uninhabitable.

Next week, Cambridge cosmologists head to London for the Royal Society's Summer Science Exhibition!

From 30 June–5 July, the Kavli Institute for Cosmology will be at Carlton House Terrace with our Simons Observatory exhibit — exploring how we're using the Cosmic Microwave Background to uncover clues about the very first moments of the Universe.

Free and open to the public. Come say hello! 🔭

IoA postdoc Dr Emilie Hertig has been selected as runner-up for the 2025 RAS Michael Penston Thesis Prize for her PhD thesis 'Probes of cosmic inflation: from the CMB to quantum analogues'.

Congratulations Emilie!

Professor of Astrophysics (1909) Hiranya Peiris has published a piece in the Bulletin of the Atomic Scientists on a structural gap in current AI safety frameworks — one that Forbes this week paired with Pope Leo XIV's encyclical on AI as two defining texts on the moment we're in.

Prof. Peiris's article: https://thebulletin.org/2026/05/ai-can-chart-a-course-to-disaster-faster-than-humans-can-notice/

Piece in Forbes: https://www.forbes.com/sites/martinwhittaker/2026/05/28/business-leaders-hold-the-pen-on-ais-next-chapter/

Leaders stand at an AI crossroads where their decisions will define the future, shaping innovation, risk and public trust in the years ahead.
