September 30, Your comment shows that you have no understanding of the actual numbers. The discovery of new clusters does NOT reduce the need for dark matter. ALL clusters contain the same, or even greater, DM fraction as the rest of the universe. Despite your repeated claim over many years that the mainstream is coming around to your view, there are NO mainstream papers that support it. I defy you to actually produce one!
Sure I can mister freelance journalist, and you can read it without having to bother with clicking a link to a different site Let's just see if you find a way to say YES to this trick question. Benni Sure I can mister freelance journalist, and you can read it without having to bother with clicking a link to a different site I have already pointed out that finding more clusters containing dark matter, does not mean that there is any less need for it to explain the observations.
You do believe in the the SM do you not? What more could be expected of a freelance journalist who never saw a Differential Equation he could solve. Your response has become so hysterical that it lacks a single element of either relevance or truth! RNP out. Your response has become so hysterical that it lacks a single element of either relevance or truth I really don't have any motivation for trying to hold a conversation with a RAVING lunatic. What do you think resides in those hundreds of previously unsuspected galaxies, RNP?
It's the ordinary matter of newly detected, previously unsuspected, galaxies that is the point: vast quantities of ordinary matter was previously left out of cosmic mass-estimates. Hence 'exotic DM' hypotheses no longer needed. Aug 19, Gravitationaly Induced Redshift In the vacuum there are trillions of galaxies where in each galaxy there are trillions of stars where in each stars there are untold trillion upon trllion atoms where in each atom are so far untold numbers of subatomic particles - In all the untold numbers of mind boggling proportions is there so much as a cats whisker - as the saying goes Ives, I met a man with seven wives, Each wife had seven sacks, Each sack had seven cats, Each cat had seven kits: Kits, cats, sacks, and wives, How many were there going to St.
Ive There is not so much as a cats whisker of darkmatter, as these numbers only contain matter where this matter is also inertial mass where its gravity over the untold billions of light years gravitaionly redshifts or blue shifts photons for us to interpet. Colour confinement "Due to a phenomenon known as color confinement, quarks are never directly observed or found in isolation; they can be found only within hadrons, which exist as either baryons which include protons and neutrons or as mesons.

There is no significant radiation from regions close enough to a BH for gravitational redshift to be significant in what we see and before you fall into the obvious trap, the accretion is disk if FAR to distant for it to be a significant effect there. All of this ordinary matter is accompanied by the appropriate amount of dark matter, leaving the overall DM fraction unchanged. So, these discoveries have NO impact with respect to DM.
Sprawling galaxy cluster found hiding in plain sight
Concerning Gravitationally Induced Redshift, the frequency shift however slight is shifted every time a photon is near or grazing a star - the effect is cumulative from star to star on its journey to earth! I suggest you spend less time and pay less attention to your logical friend as his influence is rubbing off on you - we don't want to see you rubbishing Professor of of universities Please ditch your logical friend before you fall into his mire.
Cumulative Gravitationally Induced Redshift Effect This is why you appear to be correct RNP, because as you quote the text book, the book only discuss's the isolated incidents because that is all that is necessary for the purpose of educating as it is taking for granted the cumulative effect as general knowledge RNP. See what I mean concerning your logical friends logic rubbing off on you -- it is already taking place without you noticing RNP! There is no significant radiation from regions close enough to a BH for gravitational redshift to be significant And all that other 'gravitating stuff' previously missed, which makes up the bulk of the galactic and surrounding matter distribution in that region, including the widely distributed stellar-mass Bhs and NSs not yet then assimilated into the galactic nuclei supermassive BHs.
A new article should be hitting here in a few hours. Yeah, lots of "missed gravitating stuff". Aug 20, Could you please explain why the missing "dark matter" cannot possibly be ordinary baryonic matter that has not been found yet?
Can you? I bet you cannot! I take it this "REAL SCIENCE" is only your non-evidenced-based pseudoscientific opinions that have never successfully passed peer preview because certain smart people scientists who are smarter than you or me and know much we don't will take one look at your asserted opinions and laugh their heads off because its all delusional ignorant nonsense.
If it is really true that you actually believe all these reputable and extremely intelligent scientists are "gradually coming around to your opinion" then your also have mega delusions of granular; They never will. Why do you think they have so far not shown any sign of doing so? No, no, excuse me. You missed the point. Benni thinks the observed effects attributed to DM is actually baryonic matter that has been missed by science, or missing baryonic matter. When Benni talks about "real science" or "relativity" etc. It's fun to watch him blundering about, but unable to answer even the simplest of questions when pressed.
We open another web page do we not When Benni talks about "real science" or "relativity" etc. Ojorf really, any question when asked, as you quite rightly know can easily be answered because yourself and all your logical friends just do what we are presently doing; we open another web page, do we not Ojorf. It is that Humy, dropped your brush Captain Stumpy. Maybe you haven't done much reading lately, your favorite Cosmic Fairy Dust has taken so many steps backwards lately for lack of evidence of it's existence.
Pretty soon you're gonna be down to looking in a mirror sideways for discovery of anything resembling missing matter, and won't you be surprised to find the scale wasn't out of calibration. Oh, well, Ojo needs something to do. I t was one of the great missed connections of physics. In a particle theorist derived a formula for the collision of elementary particles.
15 Months of Fresh Hell Inside Facebook | WIRED
Twenty years later two gravitation theorists, using completely different techniques, derived a formula for the collision of stars or black holes. And they were the same formula. But evidently no 6-year-old did, so their resemblance went unnoticed until Strominger realized it in What the formulas have in common is that they concern how gravity and other forces act on large scales. Strominger and his colleagues have been investigating how they may offer a new and unusual path to unifying the laws of physics. The large-scale behavior of forces turns out to hold as many surprises as the small-scale behavior that physicists traditionally focus on.
The theory specifies how different observers moving at a constant velocity relative to one another can disagree on the length of objects and the time between events.
The full general theory of relativity, meanwhile, extends that principle to observers moving at varying velocities. It specifies how space and time are woven together to form a four-dimensional spacetime fabric that bends and warps around massive gravitating bodies. The textbooks say that the general theory reduces to special relativity when you go far—ideally, infinitely far—from a planet, star, or other gravitating body. Way out there, gravity fades to nothingness, and the usually floppy spacetime continuum should harden into a rigid framework. Because gravity diminishes with distance, planets and stars are nearly independent of one another, and what happens in our solar system depends very little on the rest of the galaxy.
Yet on close examination, Bondi and his colleagues discovered that, even when they zeroed out gravity, spacetime stayed floppy rather than becoming rigidly flat. In other words, even where there is no gravity, there is still gravity; a residue always remains. Distant planets and stars are not independent of one another after all. The textbook picture, then, is wrong, but there was no intuitive way to understand why, or what it means in practice.
At those distances, what remains are not just the symmetries of special relativity, but an infinite number of other symmetries called supertranslations. These are angle-dependent translations that relate points infinitely far from a gravitating body.
