    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?

      If a constant is defined by another constant, without a variable between, wouldn’t it be fair to simplify that into a single constant? Additionally, based solely on the article, it almost sounds like they’re inverting that, saying that Planck time and Planck length determine the speed of light and gravitational constant(?).
