Is this an absurd idea?
Do you think it's possible that dark matter is unobserved "matter" that has not collapsed into physical existence due to being observed? In the double slit experiment for example, if you fire a single electron at a time at the slits, you eventually see an interference pattern develop on the screen, one observation at a time. But if you never observed the location of the electron, would it remain an unobserved wave? So I guess I'm just wondering if dark matter is just the uncollapsed portion of the universe.
Maybe not, because we are observing a well defined gravitational influence.
