Bias, but not Exclusivity Key to Understanding Universe
Previously, it was thought that the Universe was isostatic, so there must be an equal number of counterclockwise and clockwise rotating galaxies. Now it appears not so according to this arxiv study, ‘Color Differences between Clockwise and Counterclockwise Spiral Galaxies.’
To better grasp what is being stated perform a simple physical task: Extend your right hand out with your thumb pointed upwards. The natural way that you would rotate your fingers would be counterclockwise (pointing towards yourself).
This is also the “right hand rule” in electricity (see image above). It would appear that Electromagnetism is right handed.
As described above, it appears that as objects are approaching you, they rotate counterclockwise ( i.e. your fingers). There is also the old saw about pointing a finger (blame) at others while three (3) fingers point back at you. Heh.
The opposite effect, clockwise rotation, is observed in the flights of a wood screw. The flights of a wood screw spiral to the right as you look along the screw because most people are right handed and it is easier for them to drive a right spiral screw.
Again, left-hand rotation seems to apply as something comes at you, but right hand rotation applies for things moving away.
There may a decided bias for counterclockwise rotation in galaxies and planets, but not entirely.
We do know that the Universe is expanding. It would seem logical that anything moving away from you should corkscrew to the right. The cited paper describes a red shift in the more numerous counterclockwise galaxies. Red shift is demonstrated for celestial objects moving away from us in an expanding Universe.
The less numerous clockwise galaxies show a blue shift. It would appear that they are moving towards us.
Bias exists, but not exclusivity. It seems to change as we transition from the macro level (galactic) to the micro level (the genetic level and subatomic level). Another paper shows the possible discovery of a new particle may also indicate the universe is not left-handed.
Left hand rotation is observed in fission tracks and chirality of biochemicals. That is, at least the genes that lie within the DNA molecule are left hand twist, while the outer double helix is right hand twist. So DNA can unzip for identical replication.
Take a look at this paper, ‘Are fission tracks in enantiomorphic minerals a key to the emergence of homochirality?‘
Another related item is the fact that most people are right handed. The left hand side of the brain controls the right hand side of the body. The left hemisphere of the brain carries the functions of logic, mathematics, spatial awareness, and speech. Such traits favored survivability.
It would seem at some point in scale there is a transition from left hand bias to right hand bias. I would submit that the transition occurs inside us. Genes are left-handed and the left hemisphere of the brain is the reservoir of logic. These are internal. Yet above those internal points we spiral outward with a right hand bias.
All of this discussion, if more fully examined, would point to another demonstration of Relativity. Your observations are Relative from your point of view and the scale on which you view.
As a final note, the author of the first paper cited in this essay — Lior Shamir — produced his work at Lawrence Tech. I knew this community college as I grew up in Detroit, Michigan. Shamir is publishing in MDPI, an Open Access Journal. The “mainstream” publishers appear to confine their interests to mainstream institutions and only those papers peer reviewed within the confines of a singular discipline. “Outsiders” are not deemed worthy. Yet the fact is that science in the real world spans multiple disciplines. Another lamentable aspect of the decline in good science.
