lol. Literally 90 seconds in he talks about how fast earth is going and does the whole “and yet we can’t feel anything, why isn’t it like a roller coaster” thing.
For the millionth time, the relevant thing is acceleration, not speed. If you’re on an airplane at cruising altitude you can’t feel the motion unless the airplane turns or there’s turbulence. While you’re at a constant velocity you can’t feel it.
F=ma
No a, no F
The fact that 90 seconds in he shows he doesn’t understand that does not bode well or make me think this is worth 6 hours of my time.
