It turns out that the acceleration was double the distance fallen, meaning the real mass of the ME is 2.22 * 1026kg, making it 38.28 times as massive as the Earth, and making the force of gravity 147.4% the gravity on Earth. I have updated the paper with these new values. This means that organisms on the ME would experience a greater force of gravity than those on Earth. I regret the error and would like to inform everyone of the change.
Edit: I also circled the buttons in each frame to make it easier to see.

Wyboth you are both insane and a genius

Cuboid bodies could reflect on that fact.
Could also be why it is easier to pick up blocks (all 27*64 of them).
This could also be why it is easier to destroy blocks, due to a smaller gravitational force holding them together and in place.
Also, did you look into air resistance? It could well be different.

It could be part of the cause of cuboid bodies, but that will require more research.
I don't think it would explain why the player can carry so many blocks, since smaller gravity plus smaller muscles still means that you could carry about the same amount of mass.
This also could explain why it is easier to destroy blocks, but it would only explain a small part of it because the force is 73% of ours.
Also, atmosphere depends on things other than gravity. Take Venus for example. It has nearly the same mass as Earth, but it has 95 times the atmospheric pressure of Earth. I would need other information to determine atmospheric pressure on the ME.
Thank you for the speculation, I appreciate it.

Haha, I'm not in Pre-Calculus and AP Physics for nothing. Glad you liked it!

Ofc about the more research, I was just throwing guesses about.
It could be that we have the same size muscles as on MC; the two guesses aren't related.
27% is a decent amount though.
I didn't mean pess gravity = less atmosphere , I meant falling speeds could be changed by atmosphere density, right?

Falling speeds wouldn't change, but terminal velocity would. The buttons got nowhere near terminal velocity, however.

It seems there is no wind resistance (or that it is so small it does not effect anything) seeing as every block falls at the same rate.
Wyboth why don't your retry this with sand or gravel blocks and drop them with a piston? Since those blocks actually have "gravity" I think it would be a neat twist to the experiment.
--- End quote ---
If the ME is anything like our Earth, or any planet for that matter, the sand/gravel would fall at the same rate as the buttons would. If the distances are off by a fraction of a meter, that is probably because of a difference in orthographic projection. I would think they would have the same rates. I'm too lazy to do this now, but I might just look in the future.

This may explain why Steve is dense lol
And I know if it were earth they would be the same but I was suggesting you do it with sand or gravel because they aren't the only two blocks that have gravity so it was just the thought.

Haha, thanks. I also posted it on Minecraft Wiki. It's still there, so I take that as an accomplishment.
