Note: I know Apollo happened, I'm just curious if this is verifiable.
Hoaxers will commonly claim that the footage is slowed by 50%, 67%, etc, to simulate 1/6-Earth gravity. Of course, this isn't actually what happened, because if you double the speed, or increase it by 246% as some calculations can get you, then the movements of the astronauts' arms, legs, their bounces and hops, etc are all sporadic, jumpy, and unnatural.
Of course, just "it looks unnatural" or "it looks..." isn't enough proof, as it's largely just an opinion. What I'm wondering is if there's some mathematical way we can prove it isn't slowed down, or not even mathematical, just scientific.
If not, how credible is the "it looks unnatural" or "it doesn't look right when sped up" argument? I know hoaxers who seem to be so blind that they find those movements to be natural, so I don't know. Thanks in advance.
