No duality, maybe each particle emits EM waves ?

So, it could be good because in my theory of gravitation, the gravity is the mean of an electromagnetic push follow by an electromagnetic  pull.

The notion of dark matter as a weakly interacting clump of stuff that travels with the ordinary matter is incorrect. Dark matter fills 'empty' space and is displaced by ordinary matter. Particles of ordinary move through and displace the strongly interacting dark matter, causing it to wave.

There is evidence of the strongly interacting dark matter every time a double slit experiment is performed, it's what waves.
