Atmospheric mixing prevents heavy and light gases from separating by weight
the verdict
REFUTED
the evidence says no
confidence 9/100
Scientific measurements and simulations refute the absolute claim that atmospheric mixing entirely prevents the separation of gases by weight, demonstrating that gravitational separation does occur in the stratosphere.
