  1. Wait … I kind of want one of those remote-controlled aircraft carriers, though!

    Of course, once could explain that the gravitational mass of the Earth is acting on both the toy helicopter and truck, whereas the gravitational mass of the truck is rather puny, but this guy is obviously invulnerable to scientific reasoning.

    Oh, well …

    Ha, I love it. That’s the danger of hanging your faith and identity on being a literalist: there is always someone out there who is able to out-literal you.

    Guess the guy never heard of inertial frames of reference. He should try to throw a ball on a bullet train going 100 miles an hour, to see if the ball comes back to him as soon as he releases it. BTW, inertial frames of reference are going at a constant velocity, not undergoing any acceleration, so no forces from acceleration are observed in your frame of reference (actually, our velocity magnitude is constant, but velocity is a vector, so there is actually acceleration due to changing direction, i.e. rotation). This causes a coriolis force on the ball, since we are actually in a rotating frame of reference, which slightly bends the path one way or the other, depending on whether you are in the northern or southern hemisphere (right hand rule, as I remember, with fingers wrapping in the direction of rotation, and thumb points toward deflection). But this is a small effect, and will result in the brain of the “Ken Ham” person to explode. Been a long time since I did any of that, so hopefully I got the right hand rule right….same as current flow in a wire (finger direction), and magnetic field (thumb).

    1. I like to call it the “playing with a bouncy ball on an elevator” rule.

      That might be why I’m not a physicist, though.
