One may instead change to a coordinate frame fixed in the rotating body, in which the moment of inertia tensor is constant. ☝️ In other words: MOMENTUM in theory of everything IS CONSTANT ;) Okay to say this in plain words, let's imagine two figure skaters, now one of them rotates in omega 3s^-1 and two of them rotates in opposite direction 2s^-1 -- 1s^-1 What happens if they touch? Yes, energy burst must be same like that first one rotating in 3s^-1. Now apply this theory of figure skating towards rotating neutron stars in universe or rotating black holes in universe. Whole angular momentum in universe must be this way constant.

Comments “What happens if we touch? Yes, the burst of touching derivations must be same area under graph like inertially rotating person :)”
