Was there a Big Bang?

šŸ—“ļø Start: Wed 14 Jan 2026 10:30 am
ā³ End: Wed 14 Jan 2026 12:00 pm

In 1929, Edwin Hubble established a correlation between galactic redshift and distance. For nearly a century, the prevailing scientific consensus has attributed this redshift to cosmic expansion, forming the foundation of the Big Bang theory. However, recent data from the James Webb Space Telescope (JWST) has introduced observations that challenge standard cosmological models. In this presentation, David Youll (Basingstoke u3a) reviews the historical dominance of the Big Bang theory, examines the anomalies identified by the JWST, and explores whether a ā€œTired Lightā€ model offers a more accurate framework for these new findings.

@_elena Totally agree.

I also think its important for the older generations to avoid generative AI and to keep thinking for themselves (use it or loose it).

Come to think of it, there seems few "good" uses of generative AI ... although med-gemini springs to mind.

@_elena @shollyethan @yunohost @ilja Great guide, many thanks for sharing.

Years ago (pre-cloud) I used to self host at home, but as the cloud grew there became little point in this d-i-y approach. But as you say, now the cloud has become such a bad place, the d-i-y approach is back in fashion again !

I now self-host at home (again) :



I'm now looking for a docs solution, probably onlyoffice.

I've not come across yonohost before, so I'll follow with interest further parts of your series.

How to use https://u3a.social

20th January @ 3:00 pm – 5:00 pm

This month we look at how to use the newly created social media Fediverse site https://u3a.social.

We start with a summary of past talks on the Fediverse and real time bidding (how targetted ads work) before walking through creating and using an account.  Also covered is how to find groups, friends and news sources to follow (such as users on other Fediverse sites, Bluesky and RSS).  Of course we’ll have a demo.

Fediverse sites are free of ads, tracking, algorithms, big business and billionaires … they are community sites – owned and managed by the community for the community.

As always, plenty of time is reserved for discussions.

Joining details will be emailed to subscribers.  If you aren’t a member, it’s free to join here https://u3acommunities.org/subscribe-to-computing-forum/.

Mind-blowing Advances in Materials Science

šŸ—“ļø Start: Mon 26 Jan 2026 3:00 pm
ā³ End: Mon 26 Jan 2026 4:30 pm

Speaker: Professor Mark Miodownik
University College London

Mark Miodownik is a pioneering materials scientist fascinated by how the stuff of our world—metals, ceramics, polymers, biomaterials—shapes human experience. His work celebrates the hidden stories inside everyday objects and explores how emerging materials can transform sustainability, medicine, and technology. Today’s mind-blowing advances in materials science—from self-healing structures to programmable matter and bio-inspired materials—reflect the curiosity and creativity Miodownik champions, revealing a future where smarter, greener, and more responsive materials redefine what’s possible.

Mark Miodownik’s books vividly reflect his deep passion for materials and their hidden magic. Stuff Matters—a bestselling, award-winning exploration of everyday materials—and Liquid: The Delightful and Dangerous Substances That Flow Through Our Lives both reveal his ability to turn complex science into gripping, human-centred stories.

Human migration driven by climate change goes back millions years. It continues today in far greater numbers as the Earth warms to +2C by 2050 and +3C beyond 2100. Countries need to cooperate to avoid conflict.

The Ig Nobel Prizes: 2025 edition

šŸ—“ļø Start: Wed 10 Dec 2025 10:30 am
ā³ End: Wed 10 Dec 2025 12:00 pm

For over a century, the ultimate recognition of ground-breaking scientific research has been the award of a Nobel Prize. But there’s another series of annual awards, less prestigious but no less cherished, which honour, not the greatest achievements in science, but the funniest. They’re called the ā€˜Ig’ Nobel Prizes, and, since their launch in 1991, they’ve provided a humorous insight into the quirky side of scientific research. In this light-hearted presentation, Barry Zussman, from Torridge u3a, will spill the beans (and much else besides!) on the wackiest prize-winners of 2025.

ā³ End: Tue 18 Nov 2025 5:00 pm

18th November @ 3:00 pm – 5:00 pm

This month we are fortunate that Professor Winfried Hensinger, from Sussex University, will be giving us a talk about quantum computers.

Prof Winfried Hensinger is a Professor of Quantum Technologies at the University of Sussex where heads the Sussex Ion Quantum Technology Group. He is the director of the Sussex Centre for Quantum Technologies, and he is Deputy Director and Sussex lead for the new £24M EPSRC Centre for Doctoral Training in Quantum Information Science and Technologies, a joint venture of the University of Sussex and the University of Bristol. Hensinger is also a co-founder of Universal Quantum, a full stack quantum computing company, where he serves as Chief Scientist and Chairman. Hensinger has been working for over 20 years on building quantum computers with trapped ions that can solve important industry problems. In 2017, leading an international team from Google, Aarhus University, Siegen, Riken and Sussex University, he announced the first industrial blueprint for building a practical quantum computer with millions of qubits capable of solving important industry problems.

As usual, plenty of time is reserved for discussions.

This event is open to U3ACommunities computing, science and leading edge groups as well as the u3a science online interest group.

Joining details will be emailed to subscribers.  If you aren’t a member, it’s free to join here https://u3acommunities.org/subscribe-to-computing-forum/.
