Reality can be defined as the energy of a wave.
I agree, and would add that Reality is the sum of the wave energy that traverses the medium of space.
Each object within a specific universe of the multi-verse can be defined by a wave vibrating at a certain frequency that does not escape from the whole of which it is part, and possessing a certain energy level.
It is true that there is some aspect of wave energy and some "interaction caused" vibrations of bound particles associated with each object, but Reality is specific.
I use "specific" to mean two things:
1. Individuals form their own concept of reality and so it is specific to the individual. Scientific consensus and generally accepted facts of nature play a role in our individual concept of reality, but that role differs from individual to individual, and does not constitute the sum of reality. Though certainly reality is more than the generally accepted science, and may be quite different in many respects from that consensus, no individual concept of reality can lay claim to being the Truth.
2. Reality in terms of the nature of the universe is specific, in that it can be only one way. There are a potentially infinite number of specifics depending on your level of focus. Focus can range from the internal composition of a particle, the forces that govern the nature of particles and their interactions, the configuration of groups of particles into objects, the relationship between objects, and the history and future of all of those individual foci and their connections.
Describing reality is the work of science. Knowing reality is the work of the individual who seeks his or her own particular understanding to his or her own standards of satisfaction.
You won't get the answer as to what Reality is by asking questions in a physics and math forum, unless answers like you have gotten here satisfy you. But you may be intending to spark conversation with the members of the community, and that is reasonable endeavour if one spends much time contemplating reality.
The universe is as it is, and can be no other way. I personally evolve my view of reality to include the position that nature is governed by universal invariant natural laws. I also acknowledge that science has described and attempts to describe many of the laws of nature, and yet there are many natural laws that we do not understand, and probably many that we do not know about.
Question: what is the relationship between the overall universe's wave and the waves of each constituent object?
The waves of each constituent object make up the overall universe's wave.
