Physics and mathematics are part of bigger picture called science, albeit some will argue the point that mathematics isn't a science.
Science doesn't forbid anything, not something being created from nothing, not an event without a cause, not a deity, not a pink unicorn, et al. In fact science doesn't have an opinion at all. It is only the insignificance of human intelligence which usually forbids and denys things.
Generally speaking, what we often find is, when we gain greater knowledge, that which was created from nothing, or that which seemingly exists without a cause, has had a cause all along, we just didn't have the knowledge to see it or be able to explain it.
That doesn't invalidate the inevitable logical conclusion that there is "stuff" without a cause. Ultimately the real question is when do you know you've reached the bottom? IMHO its when attributes explain behavior and with few assumptions...
Why the notion of a standing wave computational system. The attributes of the waves explain their behavior, which is they re-enforce each other or cancel each other out and converage on patterns based on their interactions with one another.
The assumptions are:
1. Stannding Waves with two states: 1, -1
2. Overlaping domains
3. Hyperdimensional manifolds for connectivity.
4. Will converge to a functional system such as a universe
Compared to say the electron attributes:
1. has mass
2. has spin states
3. has a electric field
4. has gravity field
Do the attributes explain the behavior of an electron? No, neither mass, fields or spin state explain:
1. The ability to aborb photons
2. The abiltity to decern what kind of photon it has absorbed
3. The ability to change its direction based on the detection of a photon
4. The ability to transform into photon(s)
5. The duality of the electron as a particle and a wave.
6. The abiltiy to extend a field.
Looking at that list there is plenty going on inside that electron that needs splaining...:sarcastic
