  The Young double-slit interference pattern produced by quantum objects, like
photons, that move through a double-slit is regarded, by the conventional
Copenhagen interpretation of Quantum Mechanics, as the evidence of the
wave-like behaviour potentially contained in the wave function. On the
contrary, a more realistic view of this phenomenon considers the quantum object
a particle accompanied by a pilot wave which would be the cause of the
interference fringes. This paper proposes a feasible experiment, based on an
easy variation of the nowadays common double-slit experimental set-ups, aimed
at detecting the effects of the pilot wave once 'detached' from the particles
that it steers. Besides, a further realistic idea, based on the geometrical
violation of Local Lorentz Invariance (LLI), is put forward as to the intrinsic
nature of the photon. This new idea along with the possibly positive results of
the experiment would allow us to shed new light on the real nature of quantum
objects in term of the geometrical violation of LLI.
