The Head of Theoretical Physics at Cern Gian Guidice presents an idea of Big Bang powered by energy stored in the "fabric of space and time" as "vacuum energy", in an interview about the question "What happened before the Big Bang"?
This connects to the Neo-Newtonian Cosmology presented in previous posts starting from a small oscillating perturbation $\phi$ of a zero gravitational potential $\Phi = 0$, which creates mass density $\rho$ of variable sign through the action of the Laplace differential operator $\Delta$ on $\phi$ as
- $\rho =\Delta\phi$ (*)
The action of differentiation inflates small oscillations of $\phi$ around zero into large oscillations of mass density of variable sign. By the action of gravitation mass separates into larger regions of positive and negative mass, which repel each other as if subject to dark energy, with small positive $\Delta\phi$ appearing as dark matter. Further, gravitational collapse of regions of positive mass generates massive kinetic energy seemingly out of nothing as vacuum energy.
The action of the Laplacian $\Delta$ in the equation $\rho =\Delta\phi$ thus offers explanations of (i) vacuum energy, (ii) dark energy and (iii) dark matter, as an expression of the "fabric of 3d Euclidean space". If true, simplicity shows to be more powerful than the complexity of the current state of the art.
PS Matter made up electrons and protons appears as an analog to (*) with $\phi$ electric potential and $\rho$ charge density of variable sign, which form atoms and molecules into structures of matter as the material world endowed with mass from the gravitational potential. This leaves open the possibility that part of the gravitational potential remains to create dark mass according to (*) without material form. This connects to speculations by in particular Rupert Sheldrake.
What is then oscillating? We know electromagnetic (EM) waves oscillate. Is matter (and everything else) made of EM waves with various energy levels, configurations and densities? Was Einstein right when he came up with E=mc^2?
SvaraRaderaThe zero gravitational potential can develop oscillations from small disturbance , like the waves on the surface of a pond hit by a small stone. 3d Euclidean space acts like a pre-strained string, which does not vibrate, but has a capability to start to vibrate upon small disturbance. Matter is endowed with mass by the gravitational potential.
SvaraRaderaWhat can this string be?
RaderaIt is a zero immaterial gravitational potential sensitive to the action of the Laplacian differential operator.
SvaraRaderaThis is difficult to understand, at lest for me. Wouldn't a potential in itself require a difference (differential?) between 2 states of something physical like temperature differences that would create immaterial EM radiation? At 0K there will be nothing. A small perturbation will create EM(?).
SvaraRaderaOf course, the physics of the action of the Laplacian remains to understand, if it makes sense at all. In any case, the idea is that the physics is immaterial as some kind of legal system ruling over material people. Gravitation is then independent of electromagnetics as acting in the same way on positive and electric material charges.
