I started 2022 with a post titled Things I Think Are True. It was an echo of the Hard Problems post I’d done to start 2021. That earlier post listed a (possibly surprising) number of open questions in physics. Not trivial questions, either, but big ones like: “What is time?” and “What is the shape and size of the universe?”
The post in 2022 was more of an opinion piece about things that, in the context of those open questions, I think are true. Pure speculation on my part, some of it close to mainstream thinking, some of it rather less so (but all, I would argue, grounded in what we do know).
This year, for contrast, I thought I’d make a list of stuff I don’t believe is true.
