As a corollary - is it worth changing the definition of the constant, in light of what we now know, to better reflect our improved understanding? No doubt any such change would entail a degree of hardship from those billions of us accustomed to the old value, but it would be to the benefit of potentially trillions of future humans who would have a far more elegant constant. Or is the potential gain of elegance so small - and appreciated by so few - that the change is simply not worth the effort, despite the potential advantages to future generations? Personally, I seriously doubt that any change will ever take place (barring an encounter with technologically superior alien race(s) who use the alternate value), but I also think such a change could have (and should have) been made much earlier in our history, when the eminent scientists of the era discovered the potential for a better option. Which begs the question of why we, as people who understand and recognize the potential for improved understanding, don’t make this change now, before it’s too late.
