Un exemplu pentru jimao:

A quantum effect called Delbrück scattering:

Actually, electromagnetic waves can bend light through an indirect, quantum effect – but to such a tiny degree that we cannot measure it. This quantum effect (called Delbrück scattering) "is a process where, for a short time, the photon disintegrates into an electron and positron pair," says Norbert Dragon, physicist at the Institute for Theoretical Physics in Hanover, Germany. The charged pair interacts with an EM wave and then recombines into the photon with a changed direction. Thus, the EM wave bends the light.

Poate ca este '"scump" dar nu imposibil. Cum ziceam, toate au un inceput...
