The centripetal force - electromagnetic force
The thunder experiment, discovers the centripetal electromagnetic force in the electric arc. Therefore,
gravity is not "a mystery of the mass", it is centripetal electromagnetic force, the essence of the functioning of the universe.
The terrestrial electromagnetic field is active.
Its force (the direction of sphere rays), continuously change the acceleration of substance into pressure, density, thermal energy, with focal limitations.
The characteristic effects are the structure of the planet, rotation speed, electric polarization (ionosphere)
and acceleration, which gives to substance the property of "hard mass".
Really, such substance (object) is heading towards the level of the planet structure, in compliance with its density.
As Aristotle used to say, objects lift or fall, looking for their "natural place" (density).
In the circuit of water in nature, clouds are electric capacities, object of loading and unloading (lightning).
The underground immense cavities, full of metal gases, are electric capacities, object of loading and unloading (earthquakes)
The centripetal electromagnetic force, compress energy into spheres and is cause thermal or optical radiation, macroscopic and microscopic
The impurities into conductor, are real obstacles for the electric current.
Overcoming their, generates electromagnetic centripetal force on the impurity,
which issue waves in thermal or optical range.
In the circuit of water in nature, clouds are electric capacities, object of loading and unloading, by the centripetal electromagnetic force of the planet (lightning).
