A wonderful snowy afternoon in the foothills of the Bavarian Alps ❄️ 🏔️
And of course there was some discussion of black holes too 😀

First up in our black hole discussion meeting is a talk by Prof Debora Sijacki. 💫⚫
She says the field is moving in a "very exciting" direction, citing a "pioneering idea that black holes in dwarf galaxies could be driving powerful, fast outflows that could influence their star formation rates".

Keir Starmer has appointed as his new Comms Director Tim Allan who was a board member of the hate group Sex Matters. It's no longer even pretending to adhere to its Manifesto promise to "remove indignities for trans people who deserve recognition and acceptance."

This diagram is excellent and 100000% correct.
Possible causes of your problems. It’s a diagram that (sadly) still seems relevant in 2025, so reposting a year and a bit on.

Yet again, a Green Party chooses gardening (environmentalism without socialism)
🚨NEW | Green leader candidates Adrian Ramsay and Ellie Chowns say they want trans women **banned** from women's spaces + sports.
In a Q&A, they said "gender and biological sex are not the same" and claimed "evidence" was needed for trans women to be allowed into women's spaces
