EFFECTS OF UNIVERSAL EXPANSION PREDICTED BY 2D FLUID-FLUID UNIVERSE
(Where interfacial tension of boundary is assumed analogous to the gravitational tension between masses in expanding space)
WHY DO LARGER PLANETS (formed in the accretion disk of a star) MOVE AWAY FROM THEIR SUNS?
By the time they interact with the expanding universe (the distance from the cg of larger bodies is greater and the curvature in their locality decreases), it’s easier for them to be moved outward with the expanding flow of energy (greater surface to push against). The smaller planets may stay where they are because the distance to their cg is smaller, resulting in higher curvature at their surfaces (harder for energy flow to push them outward).
WHY ARE STARS MOVING FASTER AT THE PERIPHERIES OF GALAXIES (is it black matter or energy or something simpler?)
According to velocity and acceleration in the universe, the farther from the cg, or sink (for example: the black holes at the center of galaxies), the slower the object orbits (everything else being equal). Because masses/troughs are products of sine wave superpositions on/in an interface/universe, systems/objects in the interface are moved farther from the cg/center-of-trough (as show in offset trough of illustration (similar to the cell division model)) and therefore are accelerated.
WHAT DOES THIS APPARENT OPPOSITE CURVATURE OUTSIDE NORMAL SPACE-TIME DO TO THE SPEED OF SPATIAL EXPANSION?
What happens in the vicinity of a moving object when it approaches the speed of light? If it can. Then the universe may be expanding around it at the same rate that it is traveling. Perhaps the object will never reach its target.
Since we are speaking of the acceleration of space within which the system/object is embedded, then our limiting speed of special expansion might be the limiting speed in our universal hemisphere of pi times the speed of light.
If a mass traveling at the speed of light, or approaching it, gets very massive, or curves space like a trough, then it might never reach its target. As with troughs, space might expand around crests.
So acceleration between stars may deform space in such a way that we can never arrive. What might be an optimal way to travel in space to take the least amount of time to reach our target?
Another possibility is that something we cannot predict occurs near the outer reaches of galaxies (spatial curvature is in the opposite direction and stars are seen to speed up in a given duration of time).
How will our ships behave as they enter this accelerated space? In our two-fluid flow experiments, boundaries at crests may not expand in a similar way to how space behaves with inertia in the location of a black hole (curvature of space in a trough).
SEE THE ILLUSTRATION BELOW OF AN OFFSET TROUGH AND THE CREST BULGES SURROUNDING IT SUGGESTING WHY STARS IN THE OUTER REACHES OF GALAXIES (below) SEEM TO SPEED UP. [Interfacial tension (in expanding droplet/see red flow arrows around trough) takes the place of gravitational tension (in universe).)
At very high expansion rates, the flow of infinitesimal energies (as in a fluid-fluid offset trough) has rotational components and so, result in “bulges” that give an opposite curvature just outside the highly curved (massive trough).
