1/19 The compression/static/expansion trilemma is meaningless. It comes from the naive worldly idea of the universe as a certain volume of matter existing in space and time. This idea (the same turtle and three whales) brought cosmology even to such funny absurdity: 
2/19 To understand what the universe is, first need to clear yourself of the jumble of absurdities that the BBT has turned cosmology into. Take any theory, and if it has in anamnesis the Doppler interpretation of redshift - forget it, this theory is wrong.
3/19 When you free yourself from childhood mistakes, you will have the opportunity to return to the forgotten source: the content of the concept "universe". The universe is everything. Everything that exists is the inner concepts of it. There are no concepts external to it.
4/19 It will be difficult. Of course, we are not talking about God - the creator, this unnecessary idea is not even discussed here.
It is about the rejection of the innate everyday perception of space and time.

5/19 The universe does not exist in space. Space exists in the universe. Space is a consequence of the existence of the universe.
6/19 The universe does not exist in time. Time exists in the universe. Time is a consequence of the existence of the universe. (At the same time, you will have to revise the concept of "existence", since in everyday life this is an intratemporal process.)
7/19 Following this, you must convince yourself that all other concepts, whatever they may be, are all internal to the universe. All of them are only consequences. Even math, which we regard as the language of describing universes, is an internal concept of the only one universe.
8/19 Even before this stage, you will realize how ridiculous the compression/static/expansion trilemma is.
But the importance of this stage is that you will learn to detect fictitious theories by the criterion of the presence of "godgifts" in them.

9/19 Every concept used by a scientific theory must be substantiated, otherwise the theory is unscientific.
For example, classical materialism is unscientific, because it is based on the concept of "matter" with many complex properties, the set of which is godgift.

10/19 You will formulate a requirement for a theory of everything: it is a theory, all concepts used by which are substantiated within this theory.
E.g., the string theory will never become a theory of everything, because it is based on godgifts: strings, vibrations...

11/19 So you will come to the understanding that for not to operate with godgifts, the ToE must be absolutely, extremely, terminally simple. Everything that is complex in the universe should ultimately consist of something extremely simple, simpler than which nothing exists.
12/19 In your search for a terminally simple basis, you will begin to decompose everything in the universe into simpler components. And as a result of this process, you will find that this terminally simple is information. The universe is only information and nothing else.
13/19 Strict proof that the universe is only information fits into one tweet:

14/19 Based on this knowledge, you will synthesize an information theory of everything, consisting of theory of complexity, theory of observations, and theory of realization.
Theory of realization will explain you how the universe (absurdly called "observable") works.
Theory of realization will explain you how the universe (absurdly called "observable") works.
15/19 The further you look into the depths of the evolving universe, the deeper its past you observe, and the slower the observed time flows in it. The slowing down of the passage of time that is the cause of the redshift, and not the Doppler effect.
16/19 Theory of realization will tell you a lot.
But among other things, it will explain you that humanity has a fundamental role in the universe. And that since the universe exists, humanity has successfully fulfilled this role in the future, and will complete its existence.

17/19 And, since the role is fulfilled, it does not matter at all whether humanity understands the nature of the universe, or it will remain in the midst of the pile of nonsenses of TBB.
18/19 Neanderthals played their evolutionary role, throwing stone spears at Cro-Magnons, without needing to understand Newtonian mechanics. Likewise, we will pass the baton of evolution to AI, not understanding the informational nature of the universe.
19/19 Coming back to your question.
The size of the universe is fixed, it is the same physical constant as the speed of light in vacuum, absolute zero, Planck's constant or the age of the universe. This is not a banal boundary in space, but the unattainable mathematical limit.
