I don't think he's saying that. I think he's saying that when air resistance is negligible objects fall at the same speed regardless of weight. You'll notice that supramax hasn't responded to any of the suggested examples where air resistance isn't negligible. You'll also notice that in all of the experiments supramax suggests objects are being dropped from a height of five feet or less.

I think that supramax somehow imagines that some of the rest of us disagree with the general principle that when air resistance is negligible objects fall at the same speed regardless of weight. Then again, he might just be trolling.

It's surprisingly hard to disengage a troll once you taken up the argument, isn't it?
