quantum mechanics - Does the photon field extent exceed the distance ct?


Is the extent of the electromagnetic field of a photon limited to the event horizon of ct, where c=speed of light and t=time since photon generation? Or does some component of the field fill all space instantaneously while the wave front of the virtual particle is projecting at c? If not, why not since the field can collapse instantaneously upon photon detection?

Understanding Stagnation point in pitot fluid

What is stagnation point in fluid mechanics. At the open end of the pitot tube the velocity of the fluid becomes zero.But that should result...
