Selective gravity

There's no globie engineers or physicists. Why? Because gravity doesn't work with how we feel weigh. Metals are way heavier than their mass. Weight is buoyancy and static magnetism, Mass is inertia and is conserved. Scales that tip one way normally tip the other way in an elevator going up because there you also feel inertia. One side is plastic which is very light for it's mass, the other is metal which is very heavy for it's mass, get it balanced to barely tip to the metal side, go to higher floor and it will tip to the plastic side. You don't even need an elevator you can use a fear a day cage that means there's no gravity it's static magnetism. Ufos are government aircraft using magnetic antigravity they have a strong enough magnet to overcome the air pressure and fly faster than sound without fuel
