    I don't think that Guerami is a flat-Earth believer. He seems to have a peculiar and poorly explained theoretical intuition that he feels makes belief in the reality of gravity as a fundamental force of nature unnecessary. He writes:

    "The rules of the universe are simple. An atoms position in a system is based upon its density in relation to the surrounding densities and the changes in magnetism, electricity and temperature. Density is the most important function in determining the position of an object. Density is the vibration intensity within a volume in relation to the density of the surrounding medium."

    IMO, the example of a helium balloon proves gravity exists.
    A helium balloon can only rise to a certain altitude where the air becomes so thin that an equilibrium between buoyancy and gravity is reached. It will float at that altitude, but will not (cannot) escape the earths atmosphere.

    The proof lies in taking a helium balloon above the earth's atmosphere and release it. It will fall back to earth due to gravity, until it reaches the point of equilibrium in the atmosphere again and will float there. If it loses helium and it's buoyancy diminishes it will begin to slowly fall (due to gravity) and continue to fall until all helium gone and the balloon no longer has any buoyancy and will make land-fall, due to gravity.

    Is that about right?

    Yes. Air is heavier than Helium, so the air "sinks" in relation to a Helium balloon.

    The balloon will fall back to Earth based on Earths rotation .

    I wonder what is the Earths rotation ratio , to mass ?

    Is gravity ordered space ?

    What I would like to find is the ratio between Earths mass, volume and rotation .

    The volume of Earth is ; 260 billion cubic miles

    Mass of Earth is ; 5.9722x10^24 kg

    Rotation of the Earth is ; 1000mph .

    What equations would you use to figure this out ?

    That is a misquote. I said the Earth's gravitation.
    I have no idea.
    I would tend to view it as disordered (warped) space, due to the presence of a massive object.

    Does not a " warp space " imply order ?

    river:

    What do you mean?

    Do you think that gravity is caused by rotation? (Hint: it isn't.)

    What do you mean by "ordered space"?

    A ratio is formed by dividing two quantities.

    For example, the ratio between the Earth's volume and its "rotation" would be 260 billion cubic miles per 1000 mph.

    You, could, of course, convert to different units, or simplify. For example:

    \(\frac{260,000,000,000~\text{miles}^3}{1000~mph} = 260,000,000~\text{(miles)}^2\text{hours}\)

    So, the ratio you want there is 260 million square-mile hours.[/tex]

    The balloon will fall back to Earth because of the Earth's gravity.

    Do you think gravity doesn't work at the North Pole?

    Look:
    Io (9x10^22) is 20% more massive than the Moon (5x10^22).
    Its rotation (1.8 days) is fifteen times faster than the Moon's (27 days).
    Callisto's surface g is (1.8m/s^2) - that's 12% more than the Moon (1.6m/s^2).

    Irrelevant. Rotation is unrelated to gravity.

    Does a pothole in a flat road imply "order"?

    But more to the point; if one drives on a smooth but hilly road, why does it require additional power to go uphill and less power or even controlled braking, when going downhill?

    Check out Galileo's law of falling bodies, later refined by Newton as being the result of gravitational attraction.

    The speed of an object comes into play when it is in orbit inside the gravitational field (warped space) of a massive object. But this has nothing to do with buoyancy, but with centrifugal force.
    In the case of planetary orbits, the axis of rotation of the orbiting planet lies at the center of the gravitational field created by the massive object.
