The idea that we live in a multiverse of different universes is becoming increasingly popular among physicists. Not only is it supported by important theories such as cosmic inflation, it also offers an explanation of why certain numbers in physics (such as values of forces and masses) fall within a very narrow and suspiciously lucky range that enables life to exist.

If there are many different universes out there, some should, statistically speaking, be able to support life. But experts in the mathematics of probability are now questioning this argument, proposing that it may be the product of a common fallacy in thinking.

Much of the film and TV industry is returning to work after actors in the US ended their months-long strike earlier this week. In the UK too, strikes have proved successful tactics in the last year for a range of workers from barristers to bus drivers. It seems trade unions are more powerful than they’ve been in decades.

And the remarkable new film, How to Have Sex, is not only winning critical accliam but also trying to change how we talk about consent.

If you can be in London on Monday 13th November, then join us for our next free public event, which will look at migration and environmental displacement. There’s a lot of talk about “small boats”, but what is the reality of the situation? Immigration expert Nando Sigona has been gathering data on asylum seeking and state responses to it for years and will share some of it with us on the night. He’ll be joined by Parvati Nair, who looks at how the climate crisis is becoming a migration crisis. Always full of informative discussion, our events come with the added bonus of free pizza, so come for the dinner, stay for the expert insight.
