F= G (mM)/r^2 I'm interested in knowing why people are so obssessed with the gravitational constant G? It is obviously true that it is perfectly tuned so planets and solar system and life could form but why do we even ask this question to begin with and not others? Obviously if you know for a fact that this is the only formula that could explain the gravitational force between two objects, then yes that would be the right question. But why do we not entertain the possibility for the existance of other equations and this one being wrong? Is it just because we haven't found others yet or does this one have to be the one and only one? For example why do we have r squared in the bottom of the equation? why could that not be some other complex term such as r to the 1.9834983484344? which then in turn could account for that wierd G? Or even the equation itself could be fundamentally wrong in that it is missing another variable or something or maybe instead of multiplying the masses we should divide the larger one by the smaller one and multiply by some power of r and so on... Are we just happy to have this formula and therefore ignoring everything else just because so far this is the only one that works? am I wrong in saying: until we are convinced this is the only formula (THE right formula) to explain gravitational force we should avoid requiring an answer to the question "why is G so well tuned?"
