What Is Metaphysics?

What is Metaphysics? It is the study of the one substance that necessarily exists and causes / connects the many material things we observe. It is useful to quote Aristotle since he first formalised the subject of metaphysics.
The first philosophy (Metaphysics) is universal and is exclusively concerned with primary substance. ... And here we will have the science to study that which is just as that which is, both in its essence and in the properties which, just as a thing that is, it has.
The entire preoccupation of the physicist is with things that contain within themselves a principle of movement and rest. And to seek for this is to seek for the second kind of principle, that from which comes the beginning of the change. (Aristotle, Metaphysics, 340BC)
2. The one substance is this space we all experience existing in. As only one substance, space, exists it cannot be bounded by, created from, or contain another substance - thus it is necessarily infinite, eternal and continuous.
3. What are the Properties of Space? It is a continuously connected wave medium - it has waves flowing through it. (It may have more properties - I do not know.)

4. The many material things that we see as discrete and separate 'particles' moving around in this space are really formed from wave motions of this space (space is vibrating).

5. By describing matter with a spherical in out wave structure we can understand how the particle effect forms at the wave center and also how this 'particle' is in continual two way communication with other matter waves in the space around it.

6. This simplifies metaphysics from the motion of matter particles in space and time to the wave motion of space that causes matter and time. i.e. From a metaphysics of space and time to a metaphysics of space and (wave) motion.

7. This unites Science (empirical: we all experience existing in space; Occam's razor: simplicity of only space existing) with Metaphysics (space is the unity of substance...
