'What If There's a Way to Explain Quantum Physics Without the Probabilistic Weirdness?' http://www.smithsonianmag.com/smart...stic-weirdness-180951914/#JEoZGUo23dbMGJly.16 "Known as “pilot wave theory” this line of thinking goes that, rather than electrons and other things being both quasi-particles and quasi-waves, the electron is a discrete particle that is being carried along by a separate wave. What this wave is made of no one knows." 'Redefining Dark Matter - Wave Instead Of Particle' http://www.science20.com/news_articles/redefining_dark_matter_wave_instead_of_particle-139771 "Tom Broadhurst, an Ikerbasque researcher at the University of the Basque Country (UPV/EHU), explains that, "guided by the initial simulations of the formation of galaxies in this context, we have reinterpreted cold dark matter as a Bose-Einstein condensate". So, "the ultra-light bosons forming the condensate share the same quantum wave function, so disturbance patterns are formed on astronomic scales in the form of large-scale waves"." "This opens up the possibility that dark matter could be regarded as a very cold quantum fluid" Dark matter is displaced by the particles of matter which exist in it and move through it. A moving particle has an associated dark matter displacement wave. In a double slit experiment the particle travels through a single slit and the associated wave in the dark matter passes through both.
