Re: Is photon a wave packet ?

[Jack Uretsky <jlu@HEP.ANL.GOV>]

As stated, I see no meaning to the question.  Change the question to ask
what can be measured in the space.  If I put up a detector 5 seconds out,
it will respond after 5 seconds, but change what happens at the second
dettector after 10 seconds.

So the answer to why ask, is, why do you want to know?
