https://www.inverse.com/article/24863-dark-matter-might-be-smoother-than-we-thought Scientists have yet to actually observe dark matter in the flesh, but most research up to now posits it’s the kind of stuff that clumps up and aggregates into unwieldy masses around the universe. New research, however, suggests quite the opposite: dark matter is smooth as hell, distributed more evenly throughout space than we thought. http://www.space.com/27744-dark-matter-wavy-fluid-galaxies.html The mysterious dark matter that makes up most of the matter in the universe may behave more like wavy fluids Could a smoothly distributed dark matter be displaced by the particles of baryonic matter which exist in it and move through it, causing it to wave? WAVE MECHANICS by LOUIS DE BROGLIE Since 1954, when this passage was written, I have come to support wholeheartedly an hypothesis proposed by Bohm and Vigier. According to this hypothesis, the random perturbations to which the particle would be constantly subjected, and which would have the probability of presence in terms of [the wave-function wave], arise from the interaction of the particle with a “subquantic medium” which escapes our observation and is entirely chaotic, and which is everywhere present in what we call “empty space”. Could what de Broglie referred to as the "subquantic medium" be the smoothly distributed dark matter which fills 'empty' space?
