The JUNO detector, a huge sphere full of 20,000 tonnes of transparent organic goop, is detecting antineutrinos produced by two nuclear reactors each located the same distance away. After just 2 months, it measured some things about neutrino masses better than ever before! Let's dig in. (1/13)

In general relativity, a point mass just sitting there is inevitably a black hole. But that's when you're living in 3d space (and one dimension of time). In 2d space, a point mass creates a less drastic singularity: a 'cone point'. I've been studying these cone points lately, just for fun. (1/n)

A disc with a slice cut out of it, and then the cone formed when you glue together the two edges of the slice.
