  • RE: "Crunch time for dark matter hunt" by Adrian Cho, Science 25 Mar 2016

    The idea of dark matter seems to be the result of science not understanding gravity. Michio Kaku states in "Physics of the Impossible": Penguin Books, pp. 276-277 that
    "When we solve Maxwell's equations for light, we find not one but two solutions: a 'retarded' wave (corresponding to so-called real time), which represents the standard motion of light from one point to another; but also an 'advanced' wave, where the light beam goes backward in time."

    Einstein's equations say that in a universe possessing only gravitation and electromagnetism^, the gravitational fields carry enough information about electromagnetism to allow the equations of Maxwell to be restated in terms of these gravitational fields. So there are 'advanced' gravitational waves ... these are known as antigravity.

    ^ A 1919 paper by Einstein ("Do gravitational fields play an essential role in the structure of elementary particles?") implies to modern science that the 2 nuclear forces are not fundamental but, like the matter they're associated with, are products of gravitational-electromagnetic interaction.

    Antigravity is called dark energy and, if real gravity is involved in ordinary matter's mass-production, antigravity would be involved in the mass-production of other matter called "dark" (although the chance of those particles being WIMPs looks very remote).

    Adrian Chu’s report(1) points to the on-going, expensive search for dark matter particles originating in the very early Universe. My late colleague, John Reitz, and I proposed a new cosmology(2), one in which dark matter is composed of dark rotors arising from a baryon phase-transition late in the early Universe. Dark rotors(3) are neutral baryon composites at the Compton scale; they play a role in other observations in cosmology, in the solar corona, and in geophysics. Our dark rotors are not expected to be detectable in searches for wimps or axions. Detecting them will require fielding other experimental schemes. However, their existence is theoretically sound.
