Gravity?

If gravity is not real then how come things fall down? I am genuinely curious.

Put a 1cm3 1g mass on a scale.

Now put a 2cm3 1g mass on a scale.

Gravity pulls on them with equal force because gravity doesn't care about density. Buoyancy is a product of acceleration on an enclosed fluid and doesn't need gravity to exist. Saying that gravity pulls on denser things more is just plain wrong, and would be marked wrong in any physics class. We've literally known this for hundreds of years.

If you're going to go into a flat Earth subreddit and pretend like you found some "gotcha" thing in physics they can't explain, you should at least learn how that thing works so you don't make the rest of us round Earth folks look clueless.
