This thread is pure magic.🔭🧪⚛️ In 2D, gravity doesn’t make black holes — it makes "cones"! And everything turns into convex #polyhedra. #Geometry + General Relativity explained in the most elegant way. One of the best #science threads in a long time. Definitely read it! ⤵️

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)
