A thought experiment on the Origin of our Universe

I would like to propose a thought experiment to address the origin of our Universe
In the twentieth century, Edwin Hubble discovered that the universe is expanding. This led to the Big Bang theory that the universe began as a compact entity, billions of years ago and has been expanding explosively ever since. The controversial point about the Big bang theory is what was the state of the Universe at time zero, just before the Big Bang?
I would like to try and answer this using the undisputed Second Law of Thermodynamics as a starting point. The Second Law of Thermodynamics states that the sum total entropy of a closed physical system will spontaneously increase rather over time. This means that the Universe had a maximum degree of order at the moment of the Big Bang. This means that something had to wind the cosmological spring just prior to the Big Bang. If we consider the Universe as a closed system then we have to accept that there is a force in the Universe capable of self-winding. The only other possibility is that the Universe is not a closed system and something led to its creation in a highly enthalpic state.
I will attempt to describe one possible explanation for a singularity which could lead to the formation of the universe as we know it. Just because we can't see beyond our own universe doesn't mean that it is impossible for multiple universes to exist. I will attempt to show that it is more likely that there are multiple universes in existence.
Where did the matter and energy to create the universe come from? There are many possibilities. If we consider the universe as an open system, then a cataclysmic event such as a collision of two or more other universes in other dimensions could cause a pin-hole rupture in space-time with an extrusion of matter and energy into our dimensional reality. This solves the problem of how all the matter and energy in our expanding universe originated from such a small space. It doesn’t explain the ultimate beginning of everything since the source of our reality came from another reality which needed to begin at some time from something.
If we consider the universe as a closed system, one possible explanation for the beginning of the universe is that the universe that we live in may have begun from a seed, which we call a singularity. A singularity is a state in which the natural laws as we understand them do not apply. Such as a massive collection of wave-particles where the attractive forces such as gravity outweigh the repulsive forces between the particles. As the particles become increasingly more compact, they have to become increasingly ordered in order to fit into a smaller space. This is analogous to a lump of coal being compacted into a diamond. Massive extremely ordered singularities can be formed from a contracting universe. Also a massive star which has spent is fuel can contract to form a singularity as long as its mass exceeds the Chandrasekhar limit so that the uncertainty principle doesn't prevent its formation. Once the singularity is formed it will curve space and suck in anything that ventures into its event horizon. If the singularity is in dense space such as the center of a galaxy, it will grow into a super-massive black hole like a snowball rolling down a hill.
The extreme conditions inside the singularity may result in the metamorphosis of matter, energy and forces into a substance that is more uniform and has properties we can't accurately predict. The law of conservation of energy and matter and increasing entropy predict that the contents of the singularity are not destroyed and potential energy is stored in the form of enthalpy. I would like to propose a model where as the matter and energy reach a critical mass, it is converted into a highly ordered protosubstance which is recycled to create new universes. This protosubstance consists of proto wave-particles that are the precursors of all the matter and energy in the universe. It has tremendous potential energy in the form of stored enthalpy.
Singularities aren't necessarily single. If there are multiple singularities with enough mass and energy to create an entire universe, they may lead to multiple universes. It's also possible that one singularity can lead to multiple universes, by way of chaos theory. Chaos theory predicts that a certain amount of chaos is inevitable even inside a singularity. Chaos is the necessary ingredient leading to multiple possible histories as the entropy of the singularity increases. These multiple histories may lead to multiple universes from a single singularity.
Singularities may vary according to certain factors such as the amount of protosubstance which determines the virtual mass of the singularity and the amount and type of chaos contained within that protosubstance. I'm going to leave the math such as the calculations of the critical mass to the mathematicians and theoretical physicists.
The singularity exists in zero-time. It is completely uniform in an unstable equilibrium. As soon as time starts, the enthalpic potential energy is converted to kinetic energy. One scenario is a big bang of entropy and the universe begins to expand as a uniform bubble. In this scenario, one focus of disorder leads to a chain reaction affecting the entire singularity in an expanding wave-like manner. Another possibility is where multiple foci of disorder, form almost simultaneously leading to a Big-Boil, where multiple discrete bubbles of expanding entropy, that evaporate into multiple discrete universes.
As the protosubstance releases energy in the form of kinetic energy it releases quantas of eternal photons while generating pairs of elementary particles and anti-particles that form according to the rules of duality. The amount and type of chaos contained within the singularity will influence the distribution of elementary particles and energy created as the entropy of the singularity is released.
