In 1909 Robert Millikan devised an ingenious experiment to figure out the charge of an electron using a drop of oil. Let’s talk about this Nobel Prize winning experiment

I, and I think most of the space nerd community, would make a video viral within in our sect, if you made the ultimate test of the universality of natural laws by combing your head(!) and then measured the charge of your comb with your kitchen water tap. And then combed your children. (I think it is safe to use them as lab rats for this particular experiment.)
Scientists love to talk about gravity out of both sides of their mouths. In this lecture, you both talk about the “force” of gravity when you know full well Einstein replaced Newton’s idea of gravity force with a warping of spacetime. Excuse me, but I don’t see how you can have it both ways. Are you rejecting Mr. Einstein’s spacetime that most accept these days? If not, then I invite you to rephrase your dialog to replace anachronistic “force” for spacetime.
