Well fellows we all know according to newtonian physics all things fall on earth due to gravity factor.Its always confusing for me that its gravity the only factor for stabling things on earth or kept us stand on earth.I think its Air pressure too(a major factor) that help us stand on earth.I hypothise Any where its air pressure that cause objects to experience their weights. Like in space where there is no air pressure but vacuum, materials experience no force of attraction or weightfulness.Similerly how does gas baloons move away from earth, so it seems air play more vital role than gravity for objects weight!I would also like to mention here that in University of California a Physics processor,Micheal Ritch, claims the same thing resonating in my mind.Prof. Micheal Ritch Performed some experiments too!But to perform such an experiment needs highly restrictive environment!since when u pull air out off any object it just blow or pinch....So i think maintability factor is air pressure not Force of gravity that even varies place to place.Here i discuss this issue to share my fellows precious views specially those who are critically good at physics or geophysics!
