No, I quibbled over you wrapping it up in a box and putting a bow on it and calling it ''the science'' because you know that questions arising from the Big Bounce theory would challenge your entire shtick regarding the 2nd law. Which you spend an inordinate amount of time invoking for no other reason than to confirm you faith.
As said. I know how you operate.
It's simply not necessary to do, ding.
Do you have any idea the wall of text I would have to write to actually describe the science and how many times I have already done so?
Your bias is preventing you from seeing reality. You have a very convenient excuse. Where do you think your response falls on this matrix?
The Science of the Big Bang
We know from science that space and time had a beginning. Specifically, red shift, cosmic background radiation, Friedmann's solutions to Einstein's field equations, quantum mechanics, the First Law of Thermodynamics, the Second Law of Thermodynamics and Inflation Theory.
Red shift, cosmic background radiation and Friedmann's solutions to Einstein's field equations tells us that all matter and energy in the universe once occupied the space of 1 billionth of 1 trillionth the size of an atom and then began to expand and cool. The the First Law of Thermodynamics (i.e. conservation of energy) tells us that since that time matter and energy has only changed form. Which means that the atoms in our bodies were created from nothing when space and and time were created from nothing.
Red shift, cosmic background radiation, Friedmann's solutions to Einstein's field equations and the Second Law of Thermodynamics tells us that space and time did have a beginning. If the universe is expanding then it must have a beginning. If you follow it backwards in time, then any object must come to a boundary of space time. You cannot continue that history indefinitely. This is still true even if a universe has periods of contraction. It still has to have a beginning if expansion over weights the contraction. Physicists have been uncomfortable with the idea of a beginning since the work of Friedman which showed that the solutions of Einstein's equation showed that the universe had a beginning.
Inflation Theory, the First Law of Thermodynamics and quantum mechanics tells us that it is possible for matter to have a beginning. In a closed universe the gravitational energy which is always negative exactly compensates the positive energy of matter. So the energy of a closed universe is always zero. So nothing prevents this universe from being spontaneously created. Because the net energy is always zero. The positive energy of matter is balanced by the negative energy of the gravity of that matter which is the space time curvature of that matter. There is no conservation law that prevents the formation of such a universe. In quantum mechanics if something is not forbidden by conservation laws, then it necessarily happens with some non-zero probability. So a closed universe can spontaneously appear - through the laws of quantum mechanics - out of nothing. And in fact there is an elegant mathematical description which describes this process and shows that a tiny closed universe having very high energy can spontaneously pop into existence and immediately start to expand and cool. In this description, the same laws that describe the evolution of the universe also describe the appearance of the universe which means that the laws were in place before the universe itself.
The Big Bang began as a quantum tunneling event of paired particle production with matter/anti-matter pairs popping into existence annihilating each other and releasing massive amounts of energy as per e=mc^2 and creating more paired particles it was a chain reaction of epic, unimaginable proportions. The universe should have been filled only with radiation as particles which pop into existence do so in pairs and annihilate each other. But in this case for every 1 billion anti-matter particles that popped into existence 1 billion and 1 matter particles popped into existence. There are two theories as to why this was the case but it is unimportant to this narrative. So for whatever reason there were not perfect symmetry, the 1 billion anti matter particles and the 1 billion matter particles annihilated each and left behind the CMB. While the 1 particle per 1 billion matter particles and 1 billion anti matter particles is what was left behind and is what we call the universe.
E=mc^2 and the CMB explains and confirms the quantum tunneling event that we call the big bang. It explains all matter and energy in the universe and all the radiation in the CMB which came from the mutual annihilation of matter and anti-matter which was a result of paired particle production.
