We observe individual photons passing thru the double-slit experiment over time will form an interference pattern. The only thing it can be interfering with is itself. And if it existed in just one location, then that seems incongruent. The problem is in thinking that a photon having an exact location. It is not necessarily a single little point .. it is 'fuzzy', with only probabilities that it can be in certain locations. It is (as I understand) those probabilities 'clouds' that 'interfere' with each other, so the probabilities of the photon being at a location on the detector screen form an interference pattern. Hence when a photon must 'decide' on being in a certain location, those locations over time reflect that probability distribution. Quantum physics is strange, and often counter-intuitive. > yet it can be asked about other physical phenomena as well Indeed it can. Everything has wave/particle duality .. but whether the wave-like or particle-like behavior dominates depends on the mass (again, as I understand, I'm not as familiar with the details of quantum physics as I am with SR).

It is > not necessarily a single little point . i am the last one to think about theelectron as a point particle (it is heavily documented !!) may be we got here as a by product another prove that the eelctron is not a [point particle !! .. it is 'fuzzy', with only > probabilities that it can be in certain locations.

It really depends how you define the concepts. For example, if I pour a jug of water down a grid, can 'one body of water' really go through 'two separate slots in the grid'.

If you do not require it to be a 'point particle' then the December 26, 2004 tsunami was a single physical entity. It struck several places around the Indian ocean, including striking *simultaneously" ot two "separated" locations - Sri Lanka and the east coast of India. http://upload.wikimedia.org/wikipedia/commons/4/47/2004_Indonesia_Tsunami_Complete.gif Tom Davidson Richmond, VA |
