Hi - I have a question about wormholes, specifically when the two endpoints have a different gravitational potential. If we imagine the technology extisted to create a person sized wormhole between say the Earth and the moon, I think the popular perception would be that one could simply walk...

Lets say the detector is connected by a mechanical arm to pencil that records the detection event on a piece of paper i.e storage device = pencil+paper. If the lead on the pencil breaks, does the interference pattern come back?

A little while ago I posted a question https://www.physicsforums.com/newreply.php?do=newreply&noquote=1&p=4460761 A number of objections were posted to the idea which I think might be relevant to this discussion:

Isnt this like saying "the ocean is made of waves"? Actually the ocean is made of sea water - waves are things that happen in the ocean. So photons are excitations in the photon field (but don't ask me what the photon field is made of)

"nature abhors infinitey" - in this case infinite precision - might be the general principle...

I found a related thread: https://www.physicsforums.com/showthread.php?t=508484 which references the paper AIP Conf. Proc. 810 (2006), 360 by Ghenadie N. Mardari: I'll attempt to read it but I doubt it will make much sense to me. Thanks again for your responses

Thanks everyone for the responses. I wonder what the record is for the slowest double-slit experiment? Has anyone actually seriously looked for a change in the observed interference pattern as the interval between photons is increased?

The usual interpretation of the double slit experiment, when done with a single photon at a time, is that the photon must interfere with itself. However interference cannot be measured in a single-photon experiment - it requires a large number of photons to manifest a discernible interference...
