The math here is beyond me, but this statement from the paper seems contradictory:
The obtained equation is covariant in space–time and invariant with respect to any Planck scale. Therefore, the constants of the universe can be reduced to only two quantities: Planck length and Planck time.
Planck time is derived from the speed of light and the gravitational constant. So wouldn’t there be at least four universal constants?
You’re conflating “voting for a single-seat position” with any method of vote counting. There’s only ever one winner if there’s one seat, but there are better ways of counting votes than first-past-the-post. At least with ranked-choice, more people are happy with the outcome because the winner might be their second preferred option.
