Something doesn't seem right about it, from the nearest neighbor concept to enumeration in general but if it's proven (as in the Jean Chretien sense) then so be it.

We still don't know the gravitational constant to much better accuracy than Henry Cavendish in 1798, who had obtained ~1.% accuracy. Multiple experiments indicate individual error estimates of as low as ~20 ppm but their error bars are scattered collectively over ~0.1% (10-3). Quite a contrast to the ~10-12 or better uncertainty in the Rydberg constant. https://physicstoday.scitation.org/d...1063/PT.3.2447

There is a similar problem with the cosmological constant. Maybe they just are no constants ?

Last fiddled with by Till on 2022-01-31 at 20:52 Reason: cosmological constant

Wow. So, you simply ignore the arguments showing your "proof" is wrong, say those making them are "incompetent," and that makes your proof good enough to publish.

I can see it now. "Proof that two plus two is five published after long struggle..."

Actually that is true.

five
