Exactly as stated.who agrees that air pressure is gravity and that there are no attractions in nature except for obvious ones?

So if we put a steel ball in a vacuum chamber it would be weightless?

I don't think that air pressure is responsible for gravitational attraction.

Our moon is held to the Earth by gravity, and it is many many thousands of miles above where our atmosphere ends (there is no obvious boundry to our atmosphere, but it is negligible beyond a few hundred miles above the ground)

Similarly, gravity holds the Earth to the Sun, and that is many millions of miles away (and with even less "air pressure" between us)

Similarly the whole galaxy is held together by gravity, with essentially no air pressure around to blame.

You can also do some experiments at home to show they different forces of pressure and gravity, including the one mentioned by Colin:

OK then tell me what you think causes the air pressure. Why doesn't the air just dissipate? It gets less dense and therefore the pressure drops with altitude. Try breathing at high altitude. You seem to be good at asking questions. Give me some sensible answers.

Jeffrey's given you the answer - air pressure is caused by gravity, so where's your air pressure going to come from if you do away with gravity?

Another thing you might want to consider (and thanks to TheBox for providing this thought in another thread): if you jump out of a plane, why do you fall rather than just float where you are, held up by the air pressure below you which is slighly higher than the pressure above?

No.Vacuum is the lightest on earth, and a perfect vacuum is impossible to replicate. Although we can remove 98% air,theres many other molecules and pressures at work here. Im a novice here, but I want to be the first to question theories like gravity.

Anybody who believes that doesn't know what they're talking about.

For example; this "theory" can't account for planetary motion such as the moon orbiting the Earth or the Earth orbiting the Sun.

But the attraction of us and the sun is not 100% proven. There are many theories of the movements of the solar system. Some say the were all moving in a DNA spiral movement. The attraction of everything could be like elements like the salty water on earth attracts the sodium atmosphere of the moon, maybe showing the internal elements of the moon. Im no scientist in any way, just trying to come up with a solid explanation to what keeps us on the earth.

simply no, the hammer fell to the moons surface and the astronauts did not fly off the moon into space, their rocket stayed put, just fine.

The moon landing is only a video. What happened there is based on what we have been told. The moon does have an atmosphere of sodium I believe and they haven't been back there since the 70s. Strange

I think im trying to suggest that air pressure does the majority of 90% pushing us to the earth and the the earths pull is more like the other 10%.
We are told that that's how it is, but I disagree.

Its all buoyancy solely. If an uninflated balloon is thrown in the air, it falls quickly. Now inflate with your own breath, and the balloon is very light indeed. Now inflate with the surrounding air, or pure air and the balloon will be even lighter. So merely expanding the vessel and increasing surface area, weve defied gravity. The balloon should fall to the ground quicker.

I don't know what im on about, but I reckon I have an answer for most theories to an extent.

They have not been back to the moon because it is simply not very interesting,  we would rather land on a moving comet, which we have done. 

Air pressure may contribute a small percent contribution towards objects being on the ground, however this is negligible when considering dust particles blow about in a slight breeze.  The main contribution is mass and density.  The earth has a much greater mass than the moon. 

added - consider we can jump and force the air out of the way with little force.

when you jump the air does not push you back to the ground, the ground pulls you back to the ground.  The same happens on the moon with no air.

Your confusing the force of wind, wind being accelerated air etc, often blowing sideways and not pushing  down at you.

Since I have absolutely no respect for those who thinks that Lunar landing was a hoax I'm bowing out of this debate.

I don't usually quote long posts in their entirety, but I make an exception here.

These 2posts are the most understandable and rational you have ever posted - if that's not insulting you!

Just 2small points:

"The main contribution is mass and density"
Density is another way of 'saying' mass (depending on your religion :)). It takes account of volume so is a measure of the concentration of mass. When considering gravity we only use mass to calculate the force.

"we would rather land on a moving comet, which we have done"
Who is we? Do you mean the scientists and engineers who use science (which has got everything wrong) to build the spacecraft and control it?

Whatever, we are wasting our time here. Anyone who believes what this poster believes will believe anything and no one will convince him otherwise.

One final thought, you obviously disagree with his views and consider the  science faulty, yet he clearly believes it and thinks you are looking at it all wrong. His position on his views relative to yours is similar to yours relative to ours; so what makes him wrong and you right?

Anyway, I don't have time to waste on his thread, so I'm out.

One last thing. If a sphere contains a vacuum rather than being solid his theory should give to same value. I.e. the gravitational field would then be a function of geometry alone and would be independent of the mass of the gravitating body, contrary to observation.

Just to add to my earlier post #13
..........

His view is that the air pushes down. He could say that this is charged air attracted to opposite charged earth, after all you have used similar arguments. He says moon has sodium atmosphere, so again charged atoms push down. Look at what PmbPhy says in previous post.
I don't see how you can disprove this without quoting wiki or mainstream science, which he will not accept! You are just using book learning to try and disprove his logical reasoning.

Well, here it goes. I person should not feel ashamed to express his theory. That's why this is a new theory forum.Ok, so I have expressed my views.I have not stated that all we have learnt is wrong etc etc etc.I sharing my alternate view,not disproving everything.But if gravity is still a theory, then there is no definite, which I cannot disprove a theory.Kappish.So, if mythbusters had a crack at identifying and putting attraction scenarios into different piles, im saying that planets attration and us staying put on earth could be 2 different things.I asked the question if anyone agrees that it could be plausible. Of which none of you agree.So I am mearly being told im wrong about someone elses theory of gravity.attraction and repulsion are the only 2 things happening in everyday life.

If you all look into how much force is upon us,they say its a ton of air pressure acting on humans.how can a deflated balloon drop to the floor, yet an inflated 1 drift in the air.displacement.when you put your hand next to the toilet paper hanging down and pull ur hand away quickly.it follows ur hand-ish.this is displacement of molecules.if air can hold a plane in the air,it must be pretty dense.so an entire earths low atmosphere is forcing anything down that exceeds its density in molecules.everything is made of o2 like steel or iron which has 4 oxygen molecules I think.if we looked at our world in this vision, it would be amazing to show this in experiments.if u inflate a balloon with helium,and its floats to the ceiling,thats exactly what could be happening to us in the opposite direction.

People have not told you you're wrong by pointing to other theories and asserting that they are right, but by taking your theory and showing you that it's wrong. Your air pressure is driven by gravity, but you deny the gravity so you lose all the air pressure.

How can air pressure be driven by gravity?When you ram a load of helium into a tank,gravity is not present.Someone mentioned density and mass being the same thing.It is and I agree.what stops us floating off into space.well if you took all the o2 out of everything on earth and the solar system and replaced with helium,nothing would bond,and the entire solar system would possibly fall apart.

Newton and Einstein left us with theories,but no hard evidence.Theories-thats it.Mathematics is a way of making sense of what we already know and teaching it to the next generation.

My theory says that oxygen enables attraction of all heavenly bodies and keeps us to the ground.This is based on oxygen playing different roles when combined with different elements,pressures and temperatures.It makes perfect sense to me-Im just trying to convince 1 other person with intellect to agree with me(thinking outside the box).I wouldn't come on a serious chatroom like this of which I have encountered the same peoples responses-and I didn't say man didn't land on the moon-I really do not have an agenda with that,

Life at ground level is all at the same pressure-all mammals/plants etc.Our bodies are designed like this.Without oxygen,the human body would lose 65% capacity and what is left is still more dense than the outer gases and elements of which-a sphere without oxygen in space(perfect vacuum)would still be pressurised together in a more dusty ball of remainding gases and carbons.The entire solar system is made from a combination of gases.from the human body to making steel-which requires a certain amount of oxygen to keep it together.oh and metals in space do erode due to the vacuum of space.

Every question that I have ever thought of,science has proved me right-God,I love google-but this is only a theory!Peace

Where's your container with the Earth? Why doesn't the air pressure just blow the whole lot out into space? If you take a tank of any gas you fancy into space and open it, the whole lot will drift away and not hang about in a blob around you. It takes a lot of mass and a lot of gravity to hold it down.

First checkout "two ways to float a balloon without helium" on youtube.-that what got me started on this theory I guess in a way.

Ok.were getting somewhere.look up "air in space" on youtube and you will see a similar experiment with air in a water bubble in microgravity on some sort of spacestation.look at experiments of what happens in space to different things like water and a match etc.does microgravity mean it wasn't done in space itself-still interesting.

the air is pressurized by the outer layers of the atmospheres as air is denser and trapped in the centre of the sphere of earth.letting off a gas in space will indeed dissipate as a human in space would not have any gas inside it whatsoever,so no attraction there.thats why it wouldn't hang in a blob around us.unrecorded experiments on youtube will prove my theory.

the only thing doubting me is why there is no gravity on a spaceship in space?maybe this because theres not enough gas inside the spaceship to force anything anywhere.

Is this thread still going?

Gazza it is  very simple no, and not worth even trying to argue when there is physical evidence that shows air pressure does not hold us to the surface.


Do you own a set of scales?


put on it a 1oz weight,


Do you own a barometer?


witness low and high pressure readings


OBSERVE on the scales , low or high pressure on the barometer, the 1oz stays at 1 oz.


This is because 1oz is the objects mass that is influenced by the Earth's mass. The earth has a greater mass , so attracts the object.
