The BBT doesn't include a singularity. That is a popular misconception. You don't even know what you're criticising.
Gibberish.
So you don't understand entropy, let alone the complexity of applying it to the BB.
More ignorance.
BS.
You clearly don't know what a singularity is.
And you don't understand energy or its conservation.
And you don't understand space-time.
Off we go into complete fantasy and meaningless word salad.
I could go on, but I'm bored now.
As far as a singularity, if we apply Special Relativity, and you traveled at the speed of light, the modern universe would appear contracted to a singularity; point-instant. The universe didn't actually become a point-instant because you are in motion, but rather, this would appear as a relativistic reference illusion. An actual singularity does not contain velocity or Special Relativity; SR. but rather a singularity would be more a pure artifact of General Relativity; GR, based on mass at infinite density, with density defined as density=mass/(d=0+)3
If we had a purely mass based singularity expanding, since mass-density is spreading out, according to GR, space-time will expand. This creates relative motion between various components and relativity velocity. This will cause your space-time reference to see the universe appear to contracts, as it expands. Conceptually, the universe might appear to expand slower than it actually is. Our earth is a relative reference; SR, since we are part of the universal relative motion and not the center of the universe.
As far as entropy, the mistake made by many, is not realize that entropy is a state variable. Entropy is
constant for any given state. S has nothing to do with statistics. The free energy term -TS can be modeled with statistics, but it is the T or temperature, that is based on the average of kinetic motion that defines the temperature. That is a problem created by physics, They call -TS, entropy. But S is constant for any given state and does not require statistical modeling.
If you take any system, with lots of components and interactions, the entropy will be a constant. If dig into the weeds, inside that state, there are a lot of things going on at the quantum level. However, as random those may be or appear to be, these always add to a constant entropy, for that state. When we measure entropy in the lab it is a reproducible constant. What I read in physics is word salad.
To model the primordial atom or singularity, it does not matter what is going at the quantum level, the sum of all that is going on, known or unknown. begins with a constant entropy. To increase entropy, we need free energy to be absorbed, due to free energy, G=H-TS. This can occur via H, with T=0; more hefty sub particles. We can build internal energy or enthalpy into the singularity, even at absolute zero. This is H=TS, with G=0. This is a new state of higher constant entropy. If we add heat or T, the free energy increase gives energy to -TS, and this can cause S to increase into a new state of constant entropy.
It is easier to deal with entropy S, since a wide range of unknown variables average out, even as they fluctuate. Not all states average out. Only certain quantum states are stable where S=constant.
This is useful for evolution. We see distinct species, but not much in the way of missing links. The distinct species are stable entropic states where the entire critter has S=constant, no matter the complexity of the parts. The missing links tends to a more variable S, due to some of the unrefined sub-states, due to local genetic/protein changes, adding a wild card, until it is stabilized. Then we advance another step; S=K2. We have apes and then humans but no S=constant between. Physics may be modeling missing links; exceptions instead of the rule. The rules make this all more logical.
