Did you know that a man that weights 100 kg at the north pole will weight 669 g less at the equator?

Thats because the equator is further away from the center of gravity of our earth than the poles. And because the earth surface rotation is highest, leading to a centrifugal force that deletes part of the gravitational force.

For the autistics among us: of course his mass actually doesn't change. But he is pulled towards earth with .669% less force

Weight is a social construct.

no, it's because by the time he's flown from the north pole to the equator he's taken a piss and eaten, and the net effect is loss of weight

Would like to take a scale with me from Reykjavik to Nairobi and then have it show me 1 lbs less. But then I realized that I will pee, sweat, eat and drink and ejaculate during the long flight so it won’t be a scientific measurement. Could try this with my suitcase though.

Wow! 0.669% less!

Peoples' weight varies by less during the course of a single day!

Just steal an SR-71 blackbird, fix it up for a few hundred mill, land it in the north pole, put on a completely insulating suit, weigh yourself, then fly to Nairobi and fly the jet at 3000 MP/H and yank the stick so it disintegrates mid air, then skydive down to the desert and weigh yourself again.

You're safe from the autists because you meant to say "weighed" and not "massed"
unfortunately you said "weight" so you're a faggot
I'm so sorry

It'd be easier to build a new airframe than it would be to repair the blackbirds due to the way they were destroyed
