Chapter 1
Gravitation
The development of the ideas in this chapter started at the beginning of 2011.
Abstract

The choice between taking space and time smooth or corpuscular, is fallen on the latter. The undisturbed vacuum is proposed as a flat solid grid of solid marbles. The quantum of time is taken as the typical strong force reaction time 10^-23 sec.
At each coupling a particle with mass absorbs that mass from the Higgs field. Along with one mass absorption the particle also absorbs one vacuum particle. The absorbed vacuum particle IS the mass that is absorbed from the Higgs field, the Higgs field is identified with the vacuum marble grid.
Now there is one vacuum particle missing, there is a hole in the vacuum grid. The hole is now filled in from the outside, surrounding vacuum particles stream in the hole until it is filled again. The grid, first resembling a solid, now acts as a fluid, an ocean in which the masses float, a liquid Bose condensate of vacuum marbles. And when the vacuum particle sea streams, it drags along with it all masses that are floating in it.
In doing so the Newton gravitation law is derived, except for the constant. The constant is used to estimate the cross section of one vacuum particle to be about 10^-21 m.

When a velocity can be put in a box
, then the gravitational force takes its shape as an F = ma Newton dynamics.

The process of making a hole in the vacuum and the filling in of the hole from the surrounding particles, is viewed at more detail. The wavefunction of a particle is defined relative to the flat grid of the vacuum and not relative to the simulation of curvature. Albeit every subsequent moment another flat grid, another choice out of the field of all possible velocities.
