Locus is just an old term for the smallest possible point. Loci is the plural. The modern term is the Planck distance: this is the cross-section of the smallest observable event. Everything inside acts as a single point. Any event occurring at a smaller distance can never be observed. The entire universe consists of these points; they are space. A particular section of space may appear empty, or it may contain a planet. The points are still there.

Current theory of space/time

There are dimensions that extend to infinity that we readily observe as time and space; and additional dimensions which remain invisible, curled up inside each point. Each point actually consists of these additional dimensions. Matter and energy are described as existing upon and moving thru the fabric of space. There is also a shortest length of time over which an event can occur, called the Planck time. Time and space are inseparable. Both are granular.

The total number of dimensions varies according to theory, up to 26, with 11 currently being most popular. Unified theory is any theory that can explain all observed phenomena. The final number of dimensions will be determined by the level of mathematics required to get a unified theory. In Newton’s day all observed phenomena were adequately explained by 3 dimensions. There are several forms of string theory, all require 10 dimensions. M theory combines some the forms of string theory by using 11 dimensions. Since it hasn’t succeeded in combining all the forms, one or more additional dimensions may eventually be required.

Proposed changes

Instead of having 4 dimensions extending to infinity, all dimensions exist inside each single point. The interaction of points is what we observe as time and space, and is responsible for all observed phenomena. A particular set of points may express only the properties of time and volume, traditional empty space. Another set of points may express properties that we interpret as being an electron, photon, gravity or other phenomenon. All observed phenomena are an expression of the points involved. When a particle moves forward, the lead points transfer the properties of the particle to the points immediately in front of the particle. Each point within the particle transfers its properties forward to the adjacent point. The points on the trailing edge of the particle transfer their properties forward and revert to the properties of time/volume and the fields associated with the particle (gravity, magnetic, etc). The entity we perceive as a single moving particle is actually an overall expression of the points it contains. The extra dimensions determine the properties of space, and how far its properties extend (strong force, weak force, etc).

Gravity

Under Newton physics, the apogee and perigee (high and low points) of Mercury’s orbit will always point in the same direction. The orbit is described as a simple ellipse (oval).

Under Einstein, the spin of the Sun drags space with it. The orbit of Mercury precesses, the apogee and perigee move around the Sun. Instead of a simple oval, we end up with the pattern generated by a spirograph.

Problems

The actual precession of Mercury’s orbit doesn’t match the prediction. On Earth; the Moon should generate 1 tide every 24 hours, not two, and the tide generated by the Sun should be considerably less. There have been many attempts to adjust the predicted values and explain away the discrepancies, none work. We just don’t have an accurate description of gravity, so we can only roughly predict how it behaves.

How this involves Dark Matter and Dark Energy

Scientists examined galaxies and estimated the mass and rate of rotation. They consistently calculate that the galaxies don’t contain nearly enough matter (gravity) to keep them from flying apart. They have concluded that there must a lot of invisible matter providing the extra gravity. Since they can’t see it, they call it Dark Matter.

Scientists predicted that the universe is expanding but (due to gravity) the rate of expansion is slowing down. Instead, calculations indicate the rate of expansion is increasing. The increasing expansion must be caused by extra energy. Enter Dark Energy.

All this is used to explain away the discrepancies between the measured values and the predictions based on our present model of gravity. Sound familiar? We already know that our present gravitational theory is inaccurate at distances as small as from Mercury to the Sun. If these discrepancies increase nonlinearly with distance, small wonder the galaxies and the universe aren’t behaving as predicted. Before we invoke the mystic powers of Dark Energy and Dark Matter, we need a better theory of gravity. If we build on small errors, we end up with big errors. If we fix the small problems, the big ones just might go away.

Currently gravity is described as warping or bending space. Space (points) itself doesn’t move once the field is present. Time slows down as you move thru space. Time also slows down inside a gravitational field.

Proposal

If you’re not moving thru space, and time slows down in a gravitational field, then space must be moving thru you.

Gravity doesn’t just bend space, it causes it to flow continuously to the center. This can be thought of as the actual points flowing to the center and popping out of existence (nothing can shrink past the Planck distance) and reappearing in remote space. Alternately, the points can remain stationary in the gravitational field. The warping of space causes each point to generate a velocity vector, which is transferred to the gravitational center where it pops out of existence and reemerges in remote space as a new point (zero vector). The effect we call gravity is actually the combined effect of warped space and the generation of velocity vectors (or the flow of points). The two may interact in a non-linear fashion as distances increase. By adding an extra factor, there may be enough wiggle room for an accurate model of gravity.
