Sceptimatic, if it's atmospheric pressure not gravity then why is the strength of the force pulling things down proportional to mass not surface area. Why don't hollow objects get pushed down with the same force as solid objects. Also, what happened in the Cavendish experiment? How can you consider yourself open minded when you simply ignore evidence against you? Why won't you perform any experiments to prove you're theories. Please list out all the evidence you have:
What are you talking about when you say the strength of force pulling things down?
Your mind and others are fixated on mass pulling objects to them without having the faintest idea why this should be so and cannot see the more simplistic answer and would rather go with a 15th century so called thinker who decided gravity does this and that, without having a clue why he even said it, because he (assuming he did say it) sure as hell knew nothing about space...and yet... even today, after all this time, we still don't know what gravity actually is, just what it does...supposedly.
You prefer to go along with this nonsense when atmospheric pressure and magnetism explains it all, perfectly well, except of course, space and yet, good old Newton knew about as much about so called space as he did about velcro fastening Nike trainers.
You prefer to hang on to this because the sensible looking boffin in a white coat with PHD, etc on his/her pocket, or books specifically given out that says, it is what it is, so learn it, even though it doesn't really make any sense.
