The nature of Gravity
Gravity is not an externally applied force, but relies of the motion of the elementary particles.
Just like the Brownian motion at the molecular level, the elementary particles also have their own random movements. The Zero-point energy.
When the random walk takes place in space, then a particle retains the achieved speed and the new speed and direction are being added.
The direction and velocity of the particle is controlled predominantly by the external surrounding space.
Where the density of the space is greatest, the probability of direction is also greatest. -
With summation, we get a gravitational acceleration.
It's trillions of small increments each second which give the great effect.
If it is a mass wich are composed of many particles, then the result of speed and direction will be the same in a given space per. second, as it would be with a mass with only a few particles.
But if gravity = 0 then t=e^(1/3) * f^(2/3) * 3^(1/2)
Where t=time, f=distance and e=elements (in a group)
There is a ‘small’ acceleration at 0 g , but in different directions.
