I don't hate to say it. He doesn't have a clue. This is almost on par with Birthers.
We all learned how gravity works in grade school. It's been proven. There's this ride at amusement parks, I dunno if you've ever seen it, it's called the Gravitron. You yourself can generate gravity by spinning in a computer chair that has a 360 pivot joint. Pilots of performance aircraft experience gravity all the time. There's already a device that generates artificial gravity but it's far too large and far too expensive to employ anywhere (and let's be honest, we don't need it with our existing space capabilities except maybe on the ISS). Furthermore, we know how to simulate weightlessness
because we know how gravity works and thus science has calculated how to achieve it (hint: fall at the same rate as everything else in space).
I suppose next you'll try to tell us that we don't know why the sky is blue.
