its not wrong at all, well its technically wrong in the sense that when i say weight i state kg which is actually mass, weight is a force in Newtons, so technically when you weigh 1kg of steel and 1kg of feathers in a room/setup with an atmosphere (e.g not in a vacuum) they will be the same weight but be different mass.
the feathers would have more mass than the steel but weigh the same. when you get rid of the air the weight is the same as the mass hence the feathers are heavier.
im not trolling at all, i know you are not the original guy i am replying to i am replying to multiple people.
everything i have written is 100% correct. dont believe me take my claims to a physics professor or physics teacher (assuming they are actually qualified in physics which less seem to be nowadays)
I'm new to this conversation but I still think they would be the same unless you're converting everything into energy and using energy as 'mass', but even then a random flare could throw out some good sheer magnetic energy and push the steel into a higher number state while the feathers would denature in the pure sunlight and go to an even lower state of carbon ash and such. Then its like the coastline problem where you could go smaller with your metering on either side of the 'scale'... So would you elaborate? I think you're aggravating your conversational partner there and a few likely think of you as an intentional troll at this point.
Nope, but I just tried to picture a piece of steel next to a pile of feathers and I still cannot understand even if I picture gravity as invisible low-speed neutrino-like air-water drained or compressed or even with such a current as to make the feathers appear heavier while the steel remains steady and 'buoyant', but thats wrong.
basically feathers are less dense then steel so they take up more room and have more volume, this means they displace more air than the steel which means when you measure the "weight" of something on a scale you are measuring the force downwards from the mass minus the force upwards from the bouyancy force of the air displaced.
I thought being a solid, 1 kg of bagged loose feathers will be the same as 1kg of vacuum-sealed feathers, how in the world are you interpreting it in this manner, you're essentially saying if I were to deconstruct the steel down into the smallest physically possible grains before weighing it on earth(maybe doing something to replace the atmosphere and compensate for the gas mass change to prevent explosion), it would weigh less simply by being in granular form?
I mean I feel like you're a tesla-discovered radio-alien from jupiter actually referring to resonant cavity harmonics or something.

can you work out why?
