Dark Matter Missing in Milky Way and Nearby Galaxies – after thorough searches

You're Out  !

Dark Matter — You’re Out !

Gigantic pillars of Big Bang are creaking and starting to collapse like colossal dominoes. These are tumultuous times in Cosmology. Recently I described how the “The voice you hear getting louder is Brünnhilde practicing Götterdämmerung” in describing the fruitless and essentially completed search for Higgs Bosons. (Update: See “Did CERN Find a Higgs ? Well not quite. But they probably found a New Particle ! and extended their funding for years“) Well, now the hypothesis called “Dark Matter” is facing a similar fate. What a contrast with a mere five years ago when both Dark Matter and Higgs Bosons were expected to be found rapidly. A research group from University of Chile led by Moni Bidin looked carefully at the historical motions of some 400 nearby stars (up to 13,000 light years away) and found zero evidence that their motions are influenced in any way that could be attributed to the idea called Dark Matter.

Meanwhile a Russian researcher, Igor Karachentsev, looked at eleven thousand nearby galaxies to see where Dark Matter might be found around our galaxy (“Missing Dark Matter in the Local Universe“) – again finding nothing.

So if the Dark Matter conjecture is headed for the showers, then what’s going on with galaxy rotation curves? Though the mainstream science media never reported it, in 2008, two researchers (James Feng and Charles Gallo) recalculated the galaxy mass distribution vs spin and found – Gasp! that there was no problem explaining galaxy rotation curves with with ordinary Newtonian gravity and dynamics using only known visible matter.

Charles Gallo said — “We have shown that Galactic Rotation data can be described with Newtonian Gravity and Newtonian Dynamics without ‘Massive Peripheral Spherical Halos of Mysterious Dark Matter around Rotating Disk Galaxies’ and without MOND (Modified Newtonian Dynamics).”

“Our studies only obviate the need for the standard unjustified concept of ‘Massive Peripheral Spherical Halos of Mysterious Dark Matter around Rotating Disk Galaxies’.”

So Dark Matter is simply not needed to explain galaxy rotations. Plain-vanilla ordinary gravity is all that is going on. Dark Matter — R.I.P. ?

    David Dilworth:

    Dark Matter R.I.P.? No way!

    If we are to get rid of the Big Bang and the Expanding Universe we’ve got to at least make an effort. I need a well behaved Dark Mass to generate the Cosmological Redshift for a non-Expanding Universe.

    And how do you explain the results that Fred Zwicky and Vera Rubin (and others, I’m sure) with their very accurate galaxy rates-of-rotation speed measurements?

    I suggest that one should view with great suspicion when the computers used in the studies had fed into them the parameters of a Universe they believed to be: an Expanding Universe, with all its warts. Could this not bias them just a bit?

    In my paper, I conjured up an Energy with mass, a mass which could be a candidate for the Dark Mass which, then, would do its appointed tasks, which include filling the whole of Existence.

    I also firmly believe that the electro-magnetic waves need a mass to ride upon, as do magnetic fields. Remember that this Dark Mass (our vacuum?) has the characteristics of permeability and permittivity.

    The Dark Mass (Matter), especially if it is intrinsically negative as I suggested, does these jobs so well!

    The “cosmological redshifts” do not give a valuable scale of distances because the redshifts result from a (thermodynamical allowed) exchange of energy between light beams propagating in atomic hydrogen excited to 2S or 2P states (or more). Such frequency shifts are observed in labs using femtosecond light pulses (ISRS: Impulsive Stimulated Raman Scattering). These shifts may be explained replacing in the theory of refraction the coherent Rayleigh scatterings by Raman scatterings (using the 3 quadrupolar resonances in the cited states). This is ORDINARY SPECTROSCOPY. The computations show that these shifts require, with ordinary INCOHERENT light a low pressure , a long path. The experiment was done (by chance) using excited atomic hydrogen resulting from the adiabatic expansion of the solar wind between 15 AU and 20 AU. In this region, energy is transferred from the solar light to the radio waves exchanged between far probes (Pioneer 10…) and the Earth. Thermodynamics says that these radiowaves get energy, are blue-shifted. A wrong explanation is a Doppler effect, an anomalous acceleration, MOND, and so on…

  3. Doug says:

    I found the Feng and Gallo reference particularly useful – it seems in keeping with the similar work of Kenneth Nicholson on the galactic rotation problem. I was surprised in reading their work that this understanding has been around since the mid-90’s and has been largely ignored. I will try to spread the word about it – I have added references to it in a timeline articleThe 100 year wrong turn in cosmology.

    About the comments by Jacques Moret-Bailly – do you think it is possible that the mechanism of frequency shift that he describes might explain redshift in general? Is this like a tired light mechanism?

    Recently came upon your website and am writing to say that I really enjoy it. The post on the cosmic microwave radiation surprise was excellent. With all the recent nonsense about the big bang in the media, it was good to read something that made sense. Thanks for keeping the website free from jargon and math. Keep up the good work!
