How<br />long does it take to reach the halfway point at 75,000,000<br />lightyears? Remarkably, it takes 290 GY for expansion to<br />reach one half the radius of a full-size cosmic bubble.<br />This leaves only 10 GY in which to expand the balance of<br />the distance to the interface; and is achieved by a<br />relentless increase in both the speed and acceleration of<br />the outward space flow (caused by expansion). Obviously<br />comoving expansion takes a very long time, both in<br />relative and absolute terms. The prolonged slow<br />expansion and almost negligible space flow in the central<br />portion of a void, leads to an interesting possibility.<br />Part of the DSSU theory of galaxy formation is<br />described as follows: As space expands in three spatial<br />dimensions and flows radially outward from the cosmic<br />bubble’s central void, space accumulates matter by a<br />formation process in which primitive matter emerges<br />from the aether, from the fundamental fluctuators that<br />constitute aether. The primitive matter grows and evolves<br />—manifesting as conventional energy and mass particles.<br />The important point here is that matter accumulation<br />within the void depends primarily on time and<br />consequently on radial position.<br />Now if we divide the total expansion-flow time of<br />300 GY (Graph 3) into two equal time periods along the<br />full nominal radius: then 150 GY is spent along the first<br />million lightyears of length (actually considerably less<br />than one million lightyears, only 11,400 LY, using<br />equation (6-1a)); and 150 GY along the much longer 149<br />million lightyears, of the latter portion of the radius. In<br />descriptive terms, it is as if space sits leisurely at the core<br />of the void for 150 Gigayears and then spends another<br />150 Gigayears expanding completely across the void (to<br />the interface boundary). This is a disproportionate<br />consequence of the ‘miracle’ of compounding or<br />exponential growth!<br />Back to the galaxy formation process. A vital quantity<br />for determining the rate of galaxy formation is missing.<br />What is the rate of matter formation and accumulation per<br />unit of volume? Equivalently one may ask, how long does<br />it take for a galaxy to form from pure vacuum energy and<br />its derivatives? It could not possibly be a short time span<br />—otherwise the voids would not be voids and would be<br />filled with proto-galaxies and mature galaxies. It would<br />have to be as long as possible. A reasonable assumption is<br />that the time span of formation is not more than 150 GY.<br />By the time a region of matter and energy accumulation<br />reaches the interface it will have evolved into a full grown<br />elliptical. This result is predictable and observable (only<br />the evolution time is contentious but seems reasonable).<br />If we accept this conservative time frame for the<br />formation of galaxies in expanding and flowing space,<br />and we recognize that the same time span (about 150 GY)<br />and the same rate of space expansion occurs in the central<br />core (approx. one MLY radius) of the void, we can<br />reasonably surmise that galaxies also form, and even<br />mature, in this region. It is possible that galaxy formation<br />is great enough to sustain a small cluster of galaxies. The<br />result would be a void core-region where expansion<br />space-flow is actually radially inward. The geometric<br />center of each void may actually be a region of net spacecontraction.<br />Without knowing the rate of matter formation<br />per unit of volume, the size and degree of contraction<br />remains speculative.<br />Full grown galaxies arriving at the interface is an<br />observable fact; the existence of galaxies in the center of a<br />cosmic-bubble void is an interesting idea and actually has<br />been reported but not verified.Banda in barbarhttp://www.blogger.com/profile/09573682791396956162noreply@blogger.comtag:blogger.com,1999:blog-7762351538927877855.post-22019505527665508692016-03-31T09:42:05.857-07:002016-03-31T09:42:05.857-07:00A useful expansion parameter may be calculated by
...A useful expansion parameter may be calculated by<br />first selecting the length that light can travel in one of our<br />time intervals. For convenience, this would be a length of<br />1 million lightyears (the distance a light pulse travels in<br />the time of one million years).<br /> We know that this distance (sometimes called a<br />comoving coordinate distance) increases by a fractional<br />amount i every million years. The increase can be<br />expressed as,<br /> ∆ distance = 1MLY × i ,<br />then divide by our chosen time interval,<br /> ∆ distance / ∆t = (1MLY / 1MY) × i .<br />The left side is simple the definition of average speed,<br />and on the right side 1MLY ÷1MY is, by definition, the<br />speed of light c, and can be replaced by 300,000 km/s.<br />Thus,<br /> Speed of expansion = c × i .<br />Finally we divide both sides by the length of 1MLY<br />(alternately 1 mega-parsec favored by astronomers),<br />which is the coordinate length that references the<br />expansion:<br /> v /1MLY = (c i) /1MLY.<br />The left side defines the expansion parameter. The right<br />side is easily evaluated.<br /> Space expansion parameter = (c i) /1MLY (6-6)<br /> = 300,000 km/s × 0.00006226 /1MLY<br /> Space expansion parameter ≅ 18.7 km/s per MLY<br />We have, in effect, determined the value of the space<br />expansion parameter —known as Hubble’s ‘constant’ in<br />conventional cosmology— by using the cellular structure<br />of the Universe and the associated galaxy motions<br />induced by aether dynamics.<br />The Exponential Equations for Space Expansion<br />Equation (6-1) above provides a simple, intuitive,<br />approach to space expansion. The increment factor (1+ i)<br />is applied repeatedly to the growing coordinate length in<br />the same way that an interest factor is applied repeatedly<br />to a growing monetary investment. The formal method is<br />to use the expression for the relative rate of change of a<br />co-ordinate length r with respect to time:<br /><br />dr/dt ÷ r = v ⁄ r = k , (6-7)<br />where k is constant when space is expanding uniformly.<br />The expansion is described by the ratio of the rate of<br />change of a length divided by that length. Note that the<br />value of k depends not on the length units, but only on the<br />time units chosen. Constant k is simply our space<br />expansion parameter with its length units cancelled out.<br />Let us, then, replace k with the space expansion<br />parameter (which we symbolize as H) and write the<br />relative rate of change equation as,<br /><br />dr/dt ÷ r = v ⁄ r = H . (6-8)<br />Now if we choose our units so that v is in km/s and r is<br />in MLYs, then the expression could easily be mistaken for<br />the Hubble term used in conventional cosmology. The<br />identity confusion is but momentary; only until one<br />realizes that ‘their’ Hubble expansion is applied to the<br />entire visible universe, while our space expansion H is<br />applied only within the confines of cosmic cells —the<br />cosmic cells of a non-expanding universeBanda in barbarhttp://www.blogger.com/profile/09573682791396956162noreply@blogger.comtag:blogger.com,1999:blog-7762351538927877855.post-9214770850295003602016-03-31T09:40:42.441-07:002016-03-31T09:40:42.441-07:00Anomalies, however, are abundant.

With a discrepancy<br />of 5200 km/s “Stephan’s Quintet, a cluster of galaxies<br />(NGC 7317-20), gives evidence that some redshifts may<br />not be directly related to distance. The galaxies are still<br />believed to lie at the same distance, which can be<br />estimated from various indicators.” 8<br /> Another group,<br />NGC 2903, similarly has an anomaly of 6000 km/s.Banda in barbarhttp://www.blogger.com/profile/09573682791396956162noreply@blogger.com
