So where's the *proof* of Newton's Laws?
Good question, actually, since it appears it is not a law at all.. after all, the accelerating expansion of the universe violates it.
I must say, I am suprised that there are so many people who are scared of their children being exposed to various ideas, some of which are purely speculative. I would have thought that those who were confident in their beliefs would be unafraid of having their beliefs challenged... but history has shown that to be untrue time and time again, and a lot of brilliant minds went to the stake for it, so I do not know why I expected any greater enlightenment in thought now.
