Pangaea and the arrival of the Oceans
The gravitational potential at a point in a gravitational field is defined as being numerically equal to the work done in bringing a unit mass from infinity (where the potential is zero) to that point.
However to me gravity is a fluid that in its application would persuade us the recipient that though we move through space at the most incredible speed, we sense no movement.
Gravity is a fluid that however large or vigorous that object will always stay to the surface. Therefore precisely what is my theory with regard to the effects of gravity.
From 90-99% of the matter in the Universe is not radiating at any wavelength in the entire electromagnetic spectrum. That surely means the particles are most small.
