Have you asked her how to test if there is such a hair? Why she favors that hypothesis? Does she think this is magic?
Restricted to the premise that some form of Buddhism is correct, how would it fit with the idea that everything is impermanent that Buddha would have a magic hair that delays inevitable falls?
I'm not even sure one needs anything as complicated as being heavier on one side, even if the rock were uniform the center of mass would be above the cliff.
Have you got an idea how to test this, without actually raising or destroying the rock? Or maybe you got some other piece of Buddha's hair in your grandma's cellar? Impermanence is the only permanent thing I guess btw it might not be helpful; And you are obviously right about that it is only the center of the mass that matters
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
