Feynman told us that as photons and matter travel through space they take all possible paths. Some paths have greater probabilities than others, but all possible paths must be accounted for.


He also told us that once we define which path the photon or particle took all the other possibilities vanish immediately. This brings up many implications including faster than light information and something else.

We have shown that even though all the probabilities vanish in that instant the information doesn not in fact travel any faster than light. The information has to go back to its source before making its way to the other probabilities. That is my understanding anyway.


However, my question entails the still existing probabilities that are there before the photon is observed. Those probabilities are all there and all valid. I think of them as lines from a source to a destination. The density of lines is of course greatest along the shortest path (or shortest time) between the two points.

Until we pinpoint where the photon is, those other possibilities still exist. My cousin presented this question to me over Thanksgiving.

"Is it possible that all of those possibilities carry momentum and thus mass?" If this is possible then, "could that mass be the dark matter that everyone is looking for?"



As I understand it, probabilities are massless constructs. But they do exist. Are there answers to those questions?
