"... synthesized from gypsum..."

" Gypsum is a common mineral, with thick and extensive evaporite beds in association with sedimentary rocks. Deposits are known to occur in strata from as early as the Permian age. Gypsum is deposited in lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near surface exposures. It is often associated with the minerals halite and sulfur.

The word gypsum is derived from the aorist form of the Greek verb µa?e??e?? , "to cook", referring to the burnt or calcined mineral. Because the gypsum from the quarries of the Montmartre district of Paris has long furnished burnt gypsum used for various purposes, this material has been called plaster of Paris. It is also used in foot creams, shampoos and many other hair products.

Because gypsum dissolves over time in water, gypsum is rarely found in the form of sand. However, the unique conditions of the White Sands National Monument in the US state of New Mexico have created a 710 km² (275 sq mile) expanse of white gypsum sand, enough to supply the construction industry with drywall for 1,000 years."

"... electromagnetic force..."

"In physics, the Lorentz force is the force on a point charge due to electromagnetic fields. Lorentz introduced this force in 1892. However, the discovery of the Lorentz force was before Lorentz's time. In particular, it can be seen at equation (77) in Maxwell's 1861 paper On Physical Lines of Force. Later, Maxwell listed it as equation "D" of his 1864 paper, A Dynamical Theory of the Electromagnetic Field , as one of the eight original Maxwell's equations. In this paper the equation was written as follows:

\mathbf{E} = \mathbf{v} \times (\mu \mathbf{H}) - \frac{\partial\mathbf{A}}{\partial t}-\nabla \phi

where

A is the magnetic vector potential,

f is the electrostatic potential,

H is the magnetic field H ,

µ is magnetic permeability.

Although this equation is obviously a direct precursor of the modern Lorentz force equation, it actually differs in two respects:

  • It does not contain a factor of q , the charge. Maxwell didn't use the concept of charge. The definition of E used here by Maxwell is unclear. He uses the term electromotive force. He operated from Faraday's electro-tonic state A , which he considered to be a momentum in his vortex sea. The closest term that we can trace to electric charge in Maxwell's papers is the density of free electricity, which appears to refer to the density of the aethereal medium of his molecular vortices and that gives rise to the momentum A . Maxwell believed that A was a fundamental quantity from which electromotive force can be derived.
  • The equation here contains the information that what we nowadays call E , which today can be expressed in terms of scalar and vector potentials according to

 \mathbf{E} = - \nabla \phi - \frac { \partial \mathbf{A} } { \partial t }

The fact that E can be expressed this way is equivalent to one of the four modern Maxwell's equations, the Maxwell-Faraday equation.

Despite its historical origins in the original set of eight Maxwell's equations, the Lorentz force is no longer considered to be one of "Maxwell's equations" as the term is currently used (that is, as reformulated by Heaviside). It now sits adjacent to Maxwell's equations as a separate and essential law.

Significance of the Lorentz force

While the modern Maxwell's equations describe how electrically charged particles and objects give rise to electric and magnetic fields, the Lorentz force law completes that picture by describing the force acting on a moving point charge q in the presence of electromagnetic fields. The Lorentz force law describes the effect of E and B upon a point charge, but such electromagnetic forces are not the entire picture. Charged particles are possibly coupled to other forces, notably gravity and nuclear forces. Thus, Maxwell's equations do not stand separate from other physical laws, but are coupled to them via the charge and current densities. The response of a point charge to the Lorentz law is one aspect; the generation of E and B by currents and charges is another.

In real materials the Lorentz force is inadequate to describe the behavior of charged particles, both in principle and as a matter of computation. The charged particles in a material medium both respond to the E and B fields and generate these fields. Complex transport equations must be solved to determine the time and spatial response of charges, for example, the Boltzmann equation or the Fokker–Planck equation or the Navier-Stokes equations. For example, see magnetohydrodynamics, fluid dynamics, electrohydrodynamics, superconductivity, stellar evolution. An entire physical apparatus for dealing with these matters has developed. See for example, Green–Kubo relations and Green's function (many-body theory).

Although one might suggest that these theories are only approximations intended to deal with large ensembles of "point particles", perhaps a deeper perspective is that the charge-bearing particles may respond to forces like gravity, or nuclear forces, or boundary conditions."

"... quadrillion..."

"Quadrillion may mean either of the two numbers:

1,000,000,000,000,000 (one thousand million million; 10 15 ; SI prefix peta) - increasingly common meaning in English language usage.

1,000,000,000,000,000,000,000,000,000,000,000,000,000,000 (10 24 ; SI prefix yotta) - increasingly rare meaning in English language usage."

"...points of origin to establish age and duration."

"So far scientists have not found a way to determine the exact age of the Earth directly from Earth rocks because Earth's oldest rocks have been recycled and destroyed by the process of plate tectonics. If there are any of Earth's primordial rocks left in their original state, they have not yet been found. Nevertheless, scientists have been able to determine the probable age of the Solar System and to calculate an age for the Earth by assuming that the Earth and the rest of the solid bodies in the Solar System formed at the same time and are, therefore, of the same age.

The ages of Earth and Moon rocks and of meteorites are measured by the decay of long-lived radioactive isotopes of elements that occur naturally in rocks and minerals and that decay with half lives of 700 million to more than 100 billion years to stable isotopes of other elements. These dating techniques, which are firmly grounded in physics and are known collectively as radiometric dating, are used to measure the last time that the rock being dated was either melted or disturbed sufficiently to rehomogenize its radioactive elements."

"... The physical universe itself is formed from the convergence and amalgamation of many other individual universes..."

"A creation myth is a supernatural mytho-religious story or explanation that describes the beginnings of humanity, earth, life, and the universe (cosmogony), usually as a deliberate act of "creation" by a supreme being. Many accounts of creation share broadly similar themes. Common motifs include the fractionation of the things of the world from a primordial chaos; the separation of the mother and father gods; land emerging from an infinite and timeless ocean; or creation ex nihilo (Latin: out of nothing)."
