Space would be impenetrable. Actually this means that every movement, from elementary matter up to and including man, would be completely impossible. One must consider that movements are spacial occurrences. So a homogeneous space is fully inconceivable. There are always energetic movements within the 'living' space.
Some physicists speak about inconstant 'energetic fields' that at a certain place fill up space.
And of course, if this is the case it is easy understandable that also primary matter comes into being, most of the time disappearing again but sometimes developing into new phenomena. It can possibly mean the birth of a new solar system. In a way the universe is a 'living' system, not in the sense of the biological notion 'living', but in the sense that she is always in motion in herself. Since reality fundamentally is an eternal play of coming and going relations between 'immaterial particles' and, from a certain moment, 'material particles' it is necessary to think quantitatively 'in a qualitative way'. This will mean that the quality of the phenomena only can be understood on the basis of the relation between particles.
