This reminds me of the old joke about the trucker that was banging on the sides of his truck, just before he went over the DoT scale. He was carrying chickens, a huge number (overweight for the highway regulations), and he wanted the chickens airborne (within his truck) so that their weight wouldn't register on the scale. LOL. 🙂
The Pound-Rebka experiment measured the gravitational red-shift part of this, but not weight. So... since weight only has meaning in an accelerating reference frame, is this example in the video equivalent to using a Rindler coordinate transformation? (Like, standing on the surface of the Earth, measuring 9.8m/s² of proper acceleration, the photon going up or down is red or blue shifted because the top or bottom of the box is accelerating relative to the bottom or top of the box, so the Rindler transformation says that the clock of the photon emitter is faster or slower than the receiver's clock at the bottom or top of the box, right? I haven't really studied General Relativity yet, but is this exactly the same thing as the one dimensional up-down case in GR with, say, the Schwartzchild metric? (I mean, by 1D, ignoring the curvature of space in the left-right and front-back directions. Just a single up-down line.)

Freefall does not equal weightless. If the freefalling body was weightless, then it would not be freefalling and crashing to the ground.
Useless. Refuses to say that a kinetic photon has mass but says it has weight = mg on earth.. A truly confused person.
