The limits on the constants of nature are quite small for life like ours to arise, but that doesn't mean that they have to be really unlikely. Maybe there is somre reason we don't understand yet that mean that the constants have to be at their current value.
For example, I heard a talk by Guth on Cosmic Inflation and if my memory serves, one of it's successes was that it explained why the curvature of the universe would be brought to 1 by this inflation regardless of what it started at.
The problem with this ruthless approach is that in general people who don't believe in modern medicine also tend not to believe in birth control and tend the reproduce much more, completely canceling this out and often reversing this.
Barring major plagues and such, the population of the earth has historically generally increased, yet in the most developped countries the birth rate has dropped to a point were the population would decrease, if it weren't for immigration.
Do you really want Engineers in charge of designing machines? They have a vested interest not in good machines, but in more machines.
The point is that lawyers are society's experts in law, so it makes sense they should be making them. They know the most about the ones that already exist and they know how to make good ones (assuming they are good lawyers of course). The point of legalese is to be precise and to eliminate loop holes, not make laws incomprehensible.
Except that there was a precise prediction of the effect caused by the aether and the measured effect was much, much smaller(within experimental errors of zero). So even if we detect gravity waves the effects are of a much smaller magnitude than the aether theory predicts or we would have already seen them.

To answer your orignial question, the gravity in a hollow sphere is zero everywhere inside it and as if it was all concentrated at the center if you are outside it.
So the gravity of a sphere at some point in it is the same as if you had all the mass of radius less than the point concentrated at the center.
Basically, as you travel outwards from the center of a sphere of matter the gravity increases.(Mass grows like r^3 so gravity grows like r)

Note: all this assumes that I remember my classical mechanics course, I don't feel like redoing those integrals this late at night.
I know it's pretty ridiculus, but you would need to put french also, at least as prominently.
It gotten kinda crazy, but these laws are all form the 60s and 70s when English people owned a lot of the buisnesses and such, yet the population was mostly French so they decided they had to do something: The Quiet revolution and more specificly Bill 101
In fact, if you are a German or Chinese immigrant and you want to go to public school you have to go in French, you can't go in English even. To my knowledge you need to have parents that went to an English school in Quebec to be able to go to English public school. (Although you can just pay to go to a private school.)
You can have english signs, they just have to have bigger and more prominent french writing.
So there can be some english, but the french has to predominate.

(note: I think they eventually didn't actually take them down, but you get the idea.)
