Description: In contemporary physics a current Quantum Mechanics (QM) theory holds that all particles exhibit a wave nature and vice versa. However, the meaning or interpretation of this statement has not been satisfactorily resolved yet. According to the multispace conception [1] the force field and space are synonyms. Each particle has several force fields: electric, magnetic, gravity. Therefore the particle can be simultaneously in several spaces. So a photon in its own electric and magnetic spaces is a particle, but in the gravity space the photon is a wave. This phenomenon is intrinsic wave-particle duality. The scattering and collisions of fermions (electrons) can form a picture of distribution similar to wave interference. It is apparent wave-particle duality because fermions remain as lumps.
