Yes, this is correct.

The key thing about entropy for the purposes of this discussion is that it is a non-decreasing function of time, and an isolated system has an upper bound to it's entropy given by S = k ln(no. states) where no. states is the number of accessible internal states at a given energy. Applied to the universe this means the starting state has to be highly ordered so that thermodynamic processes can take place later. If the universe is an isolated system then a cyclic cosmology has a heat death problem. However, it's not clear that this applies to the universe as a whole. Penrose's idea is to dump the excess entropy into supermassive black-holes.

Originally posted by sonhouseRJ doesn't have a closed mind, but it's simply like a black hole - it absorbs everything, but can never make, or release, any sensical things out of it. Maybe it's so small now, as an single point, that it needs to borrow a bit of internal energy to cause it to implode, and then we will see a phenomenol expulsion at great speed, and maybe RJ will then see the true 'light' 😉
And perhaps, just perhaps don't you know, that MAYBE you have a closed mind. Just a guess.
Even a singular point has some internal space left, in order to borrow its own energy and cause a re-spin to explode itself... maybe... 😉

I'd explain the physics, but somehow I think it would be wasted.
Among its challenges, cyclic cosmology still needs to explain the vast shift of scale between aeons, as well as why it requires all particles to lose their mass at some point in the future.

which physics? It explains much of the physics but is an incomplete theory of everything. That doesn't mean to say that the theory couldn't eventually evolve into one that is a complete theory of everything.
Their theory may be right or wrong, but you don't come anywhere near having the intellect the mental capacity to independently come up with a valid alternative theory or even merely understand the basic physics of their theory so you are certainly in no position to criticize their theory.

Their theory may be right or wrong, but yo basic physics of their theory so you are certainly in no position to criticize their theory.
Godel's Incompleteness Theorem proved that every system that could be enclosed within a circle depended on something different outside the circle that you have to assume but you can not prove. This means that there are always more things that are true than you can prove and any system of belief, reasoning, and logic requires faith in something unproven.
Therefore, if you consider the universe as being within the circle, then it depends on something different that must be assumed, but can not be proved, that is outside the circle. So what is outside the circle containing the entire universe can be inferred by knowing what has been enclosed within the circle. What is outside the circle must be different from what is enclosed within the circle.
Therefore, there can be no mathematical formula that can explain everything, because there will always be something that can't be included in the formula that must be assumed, but can not be proven.
This proves that there is a limitation to science if only naturalitic rules can be considered.

So the circle can in fact be bigger than what we consider 'our' universe.

Of course you can't think that big when your mind is under the mind control of many other humans. You cannot think for yourself. What you think you are thinking is only the programming inherent in your so-called religion.

And maybe then the fullness of the gentiles will be complete and the Jews will say, "Blesses is He that comes in the name of the Lord."
