Space is usually considered to be nothing whatsoever.  On the contrary we suggest that space is everything.  There is nothing but space in the universe and there is only one universe.   How then can atoms etc, materialise? By gravity.  This being the movement of space in a spin.  Plain space in motion creates eddies and currents which become eventually tiny particles.  Particles by spinning on the spot in effect materialise into permanent units.  These are exerting the pull of gravity by their spin which pulls space to it.  As you know gravity is very weak and it is not surprising bearing in mind it is composed of space - normally considered to be nothing at all.   Gravity achieves great power by a great combination of atoms as in a star, say.  It is as well to remember that even in a large object such as a star every particle exerts the pull of gravity individually.   How about the other forces, magnetism. As is well known a bar of iron is readily magnetised by stroking with a magnet several times in the same direction.  This suggests that electrons are tidied up so that random positions are aligned and thus focus wasted’ energy to act in unison.  The magnetic field created by this focussed energy achieves it’s effect by spin which repels or attracts  depending only on the direction of travel.  Two north poles repel because in facing each other the electrons spin is different and therefore clashes.  Space - space repulsion.  North to south, and south to north are travelling in the same direction and thus  their opposite spins combine and attract.   A new scientific truth does not triumph by convincing it’s opponents. and making them see the light, but rather because it’s opponents eventually die, and a new generation grows up that is familiar with it.  Max Planck.
