More support for MaxHELP

Fi 7 from Fressin et al.
My MaxHELP conjecture (that the fundamental constants of the universe might be such as to maximise the expected number of Habitable Earthlike Planets) is looking increasingly plausible:
  • David Spiegel in the IAS review has an interesting article on "Life on other planets". I've reached out to him because he'd be a very good person to explore this conjecture with.
  • Tuomi et al's paper “Periodic variations in the Tau-Ceti velocities” suggests that there are earth-like planets in stars quite close to earth.
  • Fressin et al's “The False Positive Rate of KEPLER and the Occurrence of Planets” suggests that about 16% of main-sequence FGKM stars have planets whose mass is appx the same as that of Earth (85-125%). Of course these are not necessarily "Habitable Earth-like planets" since this require stable solar systems over a period of c.4bn years, which almost certainly needs a Jupiter, a very large moon, and certainly needs the star to be reasonably well-behaved and far enough away from other stars and black holes.
  • Now Bagdonaite et al in Science find "A Stringent Limit on a Drifting Proton-to-Electron Mass Ratio from Alcohol in the Early Universe" basically showing that this particular fundamental constant hasn't changed by more than 1 part in 10^7 over a period of 8 bn years.
I wonder whether the mass of the Higgs will turn out to be a fundamental constant?  This would deal with the "need" to invoke supersymmetry to "explain" it. If so we should find that d(EHelp)/d(mHiggs) = 0.  Another fascinating and testable-in-principle consequence of the MaxHelp conjecture.
