Hello all .
In feynman diagram horizontal direction is space . is that mean distance between particles ?
is that means two electron must be near a certain distance to create a virtual photon ?

Does one electron in Earth send electromagnetism force to one electron on moon by virtual photon ?
Does one electron in Earth has interaction with one electron on moon by electromagnetism force ?

Does virtual photons create in short distance ?
Creation of virtual photon depend on distance between two particles ?

Feynman diagrams are convenient shorthand for terms in a mathematical expression. They are not meant to be an underlying "billiard ball" mechanics of particle behavior.
 
virtual photons are calculational tools,that is why they are called virtual.

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
