The average atmospheric pressure at Earth's surface is about 14.6 pounds
per square inch, which is about 100,000 pascals.

What would gravity on the earth be like without this air pressure, with 0
pascals of air pressure? If you look at a helium balloon it obviously has
mass, yes.. but it has no actual weight.. if you were to measure it on a
scale. So obviously air pressure factors in to somethings weight. My
question is how much would an average person weigh if it were not for air
pressure? Or in general any discussion about the topic.

Apparently the force of gravity keeps air around the earth. Perhaps though
the air is just more dense than the near vacuum of space so it collects
itself into on place. That is my theory, as what gravity actually is..
Just an effect of buoyancy. No need to argue with me about it because I
don't have any evidence to support my idea.. yet. Solids also collect
themselves because of buoyancy in near vacuum and in air.. As does water
etc. This is why a rock will sink in water, and water will sink in air..
and helium will rise in air. Everything though will sink in the near
vacuum of space though because buoyancy is caused by density and vacuum is
the least dense of everything. It is just there is no 'down' for anything
to sink in, in vacuum so everything just collects together and creates a
down consistent with that collection of matter.

What do you think!?
