In a study published March 9 in The Monthly Notices of the Royal Astronomical Society, astronomers announced the discovery that all disk galaxies rotate about once every billion years, no matter their size or mass.
"It’s not Swiss watch precision,” said Gerhardt Meurer, an astronomer from the International Centre for Radio Astronomy Research (ICRAR), in a press release. “But regardless of whether a galaxy is very big or very small, if you could sit on the extreme edge of its disk as it spins, it would take you about a billion years to go all the way round.”
“Discovering such regularity in galaxies really helps us to better understand the mechanics that make them tick,” he said. “You won’t find a dense galaxy rotating quickly, while another with the same size but lower density is rotating more slowly.”
To carry out the study, the researchers determined the radial velocities of neutral hydrogen in the outer disks of a plethora of galaxies — ranging from small dwarf irregulars to massive spirals. These galaxies differed in both size and rotational velocity by up to a factor of 30. With these velocity measurements, the researchers were able to calculate the rotational period of their sample galaxies, which led them to conclude that the outer rims of all disk galaxies take roughly a billion years to complete one rotation. However, the researchers note that further research is required to confirm the clock-like spin rate is a universal trait of disk galaxies and not just a result of selection bias.
Based on theoretical models, the researchers also expected to find only sparse populations of young stars and interstellar gas on the outskirts of these galaxies. But instead, they discovered a significant population of much older stars mingling with the young stars and gas.
“This is an important result because knowing where a galaxy ends means we astronomers can limit our observations and not waste time, effort, and computer processing power on studying data from beyond that point,” said Meurer. “So because of this work, we now know that galaxies rotate once every billion years, with a sharp edge that’s populated with a mixture of interstellar gas [and] both old and young stars.”
Considering new generations of radio telescopes — like the long-anticipated Square Kilometer Array (SKA) — will produce massive amounts of data, the fact that researchers now have a good idea where a galaxy’s edge lies should also help them significantly reduce the power required to sort through such data.
“When the SKA comes online in the next decade,” Meurer said, “we’ll need as much help as we can get to characterize the billions of galaxies these telescopes will soon make available to us.

Matter in its physical properties depends on the revolutionary rates of its component members, the number and size of the revolving members, their distance from the nuclear body or the space content of matter, as well as on the presence of certain forces as yet undiscovered on Urantia.
What does TUB mean by "the nuclear body"?
42:1.2 Matter—energy—for they are but diverse manifestations of the same cosmic reality, as a universe phenomenon is inherent in the Universal Father. “In him all things consist.” Matter may appear to manifest inherent energy and to exhibit self-contained powers, but the lines of gravity involved in the energies concerned in all these physical phenomena are derived from, and are dependent on, Paradise, The ultimaton, the first measurable form of energy, has Paradise as its nucleus.

MidiChlorian wrote:However, if there is a period of time where Galaxies rotate and this rotation is a result of respiration then when respiration reverses would this cause rotation to change? Where as indicated in the OP, could the rotation or expansion of Galaxies cause us to see what might be considered as "dark matter" as opposed to "light matter" or visible matter?

I'm not certain of your meaning here. I can see that the nuclear region is the threshold of non-space, as Paradise is non-spacial, but a threshold to non-energy is a problem for me. I understand Paradise as the source of all physical creation. Therefore, it serves as the receiver and the transmitter of all cycled energies in the Master Universe. Havona is configured as the perfect antenna for such purposes. In fact, optimal antenna gains have recently been discovered using Archimedean spiral configurations that are elliptical, much like the circuits of Havona. (IEEE)

MidiChlorian wrote:Find in the UB where it indicates how many ultimaton's there are and then confirm that the ultimaton is a component of the electron and when these ultimatons huddle they are considered as neutral and not positive nor negative energy, they are non-energy.
MidiChlorian wrote: If paradise is the nucleus of the energy produced from ultimatons then paradise can also be coincided as the nucleus of an electron.
MidiChlorian wrote:One must have an Electron and its anti-particle in order to create matter and the components of the electron - ultimatons - and their variations and mixtures would create this anti-particle and then matter or an atom.
MidiChlorian wrote:When one split the atom it it destroyed, the UB describes what happens in order to create that atom.
MidiChlorian wrote:Also, I must now expand one of the terms that I used above "threshold" and replace it with event-horizon, which would better describe that there is a process involved and that is where you seem to interject the spiral effect but only in one direction as described in the UB.
