No. only you consider the great attractor to be an anomaly. Its mass was over estimated initially by about a factor of 10 back when a much larger mass, the Shapley Supercluster, was not known. Neither is an anomaly. - Both are very consistent with known physical laws. (More in blue text below.)Firstly the strangest thing about the Great attractor is that it exerts an attraction that suggests it comprises of trillions of star masses mass. Yet it has been found to contain considerably less mass than what would normally be expected given it's gravitational effects observed , thus it is considered an anomaly by conventional science.
On (1a) No two different centers of mass (for the same set of masses) are not possible as that would be inconsistent with the DEFINITION of Center of "A" where "A" is a well defined set of items.... (1a) Two COGS in a given mass (inertial frame ) ARE indeed possible under certain extreme circumstance. (1b)You only have to consider that the COGS relate directly to the masses HSP (hyper surface of the present) and realise the possibility that two time lines could be running very close together. t= 0 & t=0' (cog's x2) with in the single inertial frame.
But of course if you wish to stick with Minkowski/Einstein space as described under SRT and GR the possibility of such gets even harder to fathom. (2)... However as the Great attractor and the existence of Dark flow adequately prove, conventional science as we know it today is ill-equipped to allow us to understand what it is we are ACTUALLY observing.
Not my logic or conclusion. I.e. I agree the great attractor exists but it is not the largest distant concentration of masses. In fact I computed with gravity's inverse square law for forces and the inverse cube law for tidal stresses that your great attractor, as main cause of global warming instead of CO2, was more than a 1000, trillion times less important than CO2's effect on global warming.According to your logic, the Great attractor and Dark flow do not exist as they are not compatible with your understanding of physics.
More NON-SENSE from your fertile imagination. The great attractor is a mutually interacting, probably bound, set of masses with some part still in the gasses phase, not yet condensed into stars, but its mutual gravitational inter actions quite possible can eject one current member from the cluster, if time extends "for ever." That will even happen to some members of our solar system in the very distant future. A large set of gravitational bound masses tend to exhibit this "ejection of a member" if you wait long enough. I.e. many mutual gravitational "scattering" can eventually give some member the "escape velocity."The Great attractor is considered an anomaly because current science can not explain it not because it is an anomaly persee.
You can hold an opinion, with zero supporting evidence - many do about existence of God, some about the existence of "witches" etc. but I prefer to hold beliefs with supporting evidence. Again, very little is known about "dark flow" - It is only a name referring to some measurement, observation, results not yet understood - not evidence of any violation of well established laws of physic.However Dark Flow on the other hand , to me, IS evidence of a physical and not just a theoretical anomaly suggesting Universal gravitational integrity has been breached ...
No we are still at cross purposes.On (1b) I have no idea what you are speaking of and doubt you do either. What sort of math describes these things? Are skilled in the use of it? What is this "hyper surface of the present"? For me the "present" is the junction between the immutable past and the unknown future in my inertial frame. What is you definition of "present" that mixes in ANY space? Are you endorsing the "parallel universe" idea - that with every QM wave function collapse a new complete universe comes into being, which is not observable as in some "hyper space" ?
this is why i wrote:Physic is a "work in progress" not a completed area of knowledge. All the observations we don't yet understand usually are opportunities for new refinements to it. Ignorance* is not a proof that what is known is wrong. At this stage of man's understanding, it is highly probable than new understanding will only slightly revise the huge body of acquired knowledge, like Relativity did for classical physics, but that revision is normally so small that the old knowledge is still very useful. For example classical gravity laws are what is used to send space craft into orbit around Mars, etc.
I do not intend a criticism but merely stating what is already accepted.conventional science as we know it today is ill-equipped to allow us to understand what it is we are ACTUALLY observing
That is just crazy talk. Crazy.No we are still at cross purposes.
Try this example:
Time machine is developed and sends something backwards in time a set amount, creates a situation that requires the present moment to change to suit the now changed past. The present fades as it reconfigures to suit the new past. During this process there are at least two COG's for any mass.
Gosh you know the ole time paradox often referred to in fiction don't you?
The anomaly I speak of involves t=0 and t=0' occurring simultaneously in the present moment. The inertial COGs relates uniquely to each simultaneously. The separation being in time not so much distance. [however distance would be involved marginally]
The anomaly I refer to generates a time paradox. Thus generating two COGS in an inertial frame that have been forced apart and are now attempting to reunite as they must [heal], hence our planets warming and climate change is a part of a universal self justified reunification process.
That reason is mental illness.I might add, I have reason to believe that evidence to support what I am saying is currently evolving and may present itself with in the next 12 months.
Yes but QQ is working on his Ph.D. (Non-Sense Pilled Higher & Deeper.) with this idea multiple simultaneous times that are the same present time (T1, T2, T3, .... all the same instant but different.).That is just crazy talk. Crazy. ...
Barycenter could do quite nicely. I often refer to the center of a system as being a COG however Bary center could be used I guess.cog?
or
barycenter?
actually the limit to my "insanity" is for only two time lines occurring with in all mass and not more... t=0 & t=0'Yes but QQ is working on his Ph.D. (Non-Sense Pilled Higher & Deeper.) with this idea multiple simultaneous times that are the same present time (T1, T2, T3, .... all the same instant but different.).
Well .. I am in good company. You believe that "length contraction" aka SRT, can be accepted (over 100 years) with out underlying mechanism explained like most theoretical physicists, do you not?That is just crazy talk. Crazy.
That reason is mental illness.
Yes, two different sets of mass points will have two different COG. But still no one set of masses can have two different COGs as you have claimed as that violates the definition of COG (or the general definition of "center of any A" where A is a well defined set, as I have twice told and defined for you.
You will note the obvious. That the Bary Center, indicated by the red cross, is slightly off center from the COG of the larger mass and is rotating. ...
That is all your illustration is showing: different mass distribution have different COGs.{Post 349, in part}... no well defined (by some boundary) system can have two centers of any ONE thing (like gravity or population). - I illustrated that by saying there was only ONE population center for native American Indians living in the US and that it was different from that of the US total population.
In that same post, I also illustrated how the center of mass of earth and the earth/ moon system were different.
and the rest of my post indicates why there may be as I claim...Yes, two different sets of mass points will have two different COG.

I don't know it there is any sensible content to this or not. It seems to be just ill defined "symbol soup." !!!and the rest of my post indicates why there may be as I claim...
center of any system A = t=0
center of any system A' = t=0'
combined effect = system A(') = t=0 + t=0'
System A(') = t=0(')
I believe that the reduction in SIDS has been caused by prevention of SIDS through better infant care.I believe whether correctly or not that the sheer fact that my daughter, born 1984, is still alive today even if suffering chronic asthma, is direct evidence of a world healing itself of SIDS.
This is true but most of all it was because parents were monitoring their children during their sleep considerably more. [Baby heart monitors were being used as well]I believe that the reduction in SIDS has been caused by prevention of SIDS through better infant care.
http://www.asthmaaustralia.org.au/Asthma_rates_decline.aspxThe Foundation welcomed the publication of the latest Australian Institute of Health and Welfare (AIHW) asthma statistics that shows a significant decline in asthma in young people, but warns against any complacency.
The headline figures from the Asthma in Australia 2011 report released today show that between 2001 and 2007-08, the prevalence of asthma declined in people aged 5 to 34 years by over one quarter, but remained stable in adults aged 35 years and over. The report also shows a decrease in deaths from asthma, with the mortality rate due to asthma dropping by 45% between 1997 and 2009.
Actually, they do. They know that good sleep positions reduce the risk of SIDS, as does using sleep sacks, small blankets (small enough to not occlude all air when placed over the head) and "clean" (uncluttered) sleep areas. When these mitigations are used, SIDS is reduced. Since these mitigations were begun in the late 1980's, they resulted in the reduction of SIDS incidents.However medical science still has no idea what was causing SIDS and on that basis they have no idea of what caused the sudden drop in the number of deaths around 1988 either.***
But they do know that steroids and bronchiodilators can reduce the effects of asthma, and thus know why asthma deaths (not incidence, but deaths) are down.and I might add the docs. don't know what causes asthma either...
Perhaps of you look at the distinction between "cause" and "treatment" you might wish to reassess your retort.Actually, they do.

Not really. They have a very good idea of what caused the sudden drop in the number of deaths around 1988 - effective prevention.Perhaps of you look at the distinction between "cause" and "treatment" you might wish to reassess your retort.
