Question about "what the bleep do we know" and superposition of a particle. well it seems that "what the bleep" is somewhat a touchy subject to many people, ill ask my question in a different way then. question on the 2slit experiment: does a single particle actually go through both slits at once, or is it a mere assumption. since, by measuring/observing which slit it actually goes through collpases the wavefuntion. is there no possible way to come up with concrete evidence, say a video or a picture of a single particle being at multiple places, or in this case going through both slits at once? i would imagine that a video or a picture would be an act of measurement, therefor impossible?
