For this reason I propose a simplified method for levitating objects: It is sufficient to find the location of the object in the air (this takes into account the weight of the object and the air they sit on, but does not require the size and density of the object) and then measure its speed when in the air. Using such a method, the object could be levitated on three axes in any given position. This method produces an object that is spherical.
Now, here is the important part! I do not want them to fly in the air, I want them to float on a sphere. This is done by introducing a small mass in the air, and then putting two points of forces in their respective locations – one in the center of the center-mass, and one towards the outside of the sphere. This small force makes a large mass move towards the outside – thus making the object float. That’s the idea.
How does gravity do that for me?
A little while ago, I came across this wonderful video by Jelke Wissenberger which explains what happens in the air when we go through a jump. The main point is that the air does not expand uniformly. Instead, the air expands when the object is coming towards you and contracts when you go away from it. The force coming out of each of these points is equal to the force of gravity. As the weight of the object is evenly distributed within this sphere, the object will always fall.
The question here is, how does gravity work in practice on earth? It is fairly simple – the Earth’s surface (surface gravity, not air pressure) is about 2.73 g/m3 (g is the gravitational constant). But it is not quite in equilibrium with the air. Therefore the air’s temperature would increase as the amount of air mass around increases. The density of the air in the atmosphere would drop accordingly.
How much force is there
Now, suppose that the air were a sphere, and we would start to levitate the object by placing it somewhere on the surface of the sphere. If the mass that is required to raise the object were one gram, the air would move at a speed of about 0.4 cm/s. With the air density at 0.6 g/m3 it would have a speed of about 1 cm/s.
So, here is a question: How much force is there that would be required to raise an object the distance between two
