i like PETTRI RISSANENS’ theory of a rotating universe though i am aware it has been postulated before. if the fingerprint of quantum mechanics can be stretched by inflation across the heavens so might rotation though i am not sure where this intrinsic rotation may originate. one thing however that is becomming appreciably apparent is the widespread acceptance of the “metaverse” theory and that what is observable is but a fraction of a fraction of what may be reality. kind regards to all, kel.

Dark flow attraction is said to be coming from a distance of 1000 universes. Since gravity is subject to the inverse square law this implies a force moving some of our galaxies, themselves consisting of hundreds of billions of stars, that is only 1/millionth of what it is at it’s origin. Now that is some force !
Note: very odd that this astounding conjecture comes from measurements that cannot tell if the galaxies being effected are coming or going !

Can it be, that the cosmos rotates around its ‘axis’? The cosmos is so vast, that perhaps it just looks, that the dark flow seems to go towards one point, but ‘in reality’ it rotates. If there was ( before big bang) some kind of spin in progress, there should be some kind of leftover momentum, which makes the whole universe go around?

Couldn’t “dark flow” just be the result of 1) weaker gravitational forces as the galaxies spread apart + 2) solar winds pushing the galaxies faster and faster?

What if, as postulated by the string theory, the big bang was caused by membrane contact of two parallel string universes. Could our universe be moving in the direction of another contact. All matter in our universe rushing in to what essentially would become a black hole. Nothingness. Contact occurs and then another big bang?

Also see the earlier thread “Gravitational Lensing measures the Universe”.

Could this method, or another, such as gravity measurements/gravity lensing, universe curvature measurement, …, give us an idea about the size of the *entire* universe?

The only size estimates for the entire universe, that I know of, are purely theoretical and lower bounds (such as 10^23 to 10^26 times the observable universe, based on Alan Guth’s inflation theory).

I could devour sheets of acid for a week and not imagine some of the utterly incredible consequences outlined in this article. The universe is an exquisite machine, drenched in possibilities and a generator of mind blowing scenarios. It is my great hope that the supremely talented scientific elite who thrive off the consumption of physical data will one day enrich mankind’s veneer of knowledge about the universe with the ultimate theory of everything.

If everything can be decomposed into mathematics, this shouldn’t be an untenable goal.

So, these measurements hint that something beyond the visible Universe is pulling on matter within the visable Universe. How far beyond the visible Universe are we talking about? and what might be the pulling agent (black holes, dark matter, cosmic strings)?

I find this work interesting because it may lead to an estimate of how much Universe lies beyond the observable Universe. How many of you, myself included, have wondered for how many hundreds of billions or trillions of light years does the actual Universe extend? Dark flow measurements may help us put a lower limit on the size of the Universe beyond the visable part, I think.

jim yes as you left off above,indeed a whole different topic,but… a fantastically wonderful open opportunity for those of us interested in moving about the universe.i am a lucky guy to be able to talk to so many advanced individuals who are thinking about so many advanced topics for ,how shall i phrase it!? literally going anyplace in the universe.makes the stuff i followed so markedly as a young man(when i was in high school) seem primative by comparisson.no doubt about that.respectfully to one and all your friend george

Hi /Folks;

This is really interesting. In essence, we can capture signals produced by effects, or as the result of previous effects beyond our light cone of the observable universe. The latest estimate for the age of the universe is 13.75 billion plus or minus 110 million years.

Perhaps the study of such effects can blossom into a field of extra-light-cone-cosmic archeology. It would be interesting to see if other bulk mattergy streams are occuring in our universe. Perhaps refined red-shift measurement and statistical analysis of recessional velocities can find additional large flows.

If would be interesting if this dark flow was due to a black hole with a mass of about 10 EXP 20 solar masses or so.

Given that a black hole with a mass of the observable universe would just about equal the radius of the observable universe, inorder for the black hole idea to pan out, a 10 EXP 20 solar mass black hole would have a density of about {[10 EXP (23 - 20)] EXP 3 }/(10 EXP 3) times or one million times the density of the observable universe. The radius of such a black hole would be one thousandth the radius of the observable universe. If the black hole had a mass of 10 EXP 21 metric tons, the black hole would have a density of about {[10 EXP (23 - 21)] EXP 3 }/(10 EXP 2) times or about ten thousand times the density of the observable universe and the radius of the black hole would be about one hundreth the radius of the observable universe.

I could see such blackholes producing such a relatively narrow although large differential mass flow in our visible portion of the universe.

Now if these black hole are rotating, an awesome prospect of providing for a cosmic scale wormhole in the center which could open to cosmically far distant locations in our universe or perhaps open up into another universe may be in order. But this is a whole different topic.
