In Paper 101 the UB says:
"We full well know that, while the historic facts and religious truths of this series of revelatory presentations will stand on the records of the ages to come, within a few short years many of our statements regarding the physical sciences will stand in need of revision in consequence of additional scientific developments and new discoveries. These new developments we even now foresee, but we are forbidden to include such humanly undiscovered facts in the revelatory records. Let it be made clear that revelations are not necessarily inspired. The cosmology of these revelations is not inspired."
Then, it seems, wherever the Book touches on scientific explanations it basically encapsulates some of the prevailing scientific ideas of the early 20th century - there is no conception of the Big Bang, the evolution of the solar system follows a subsequently outdated model, mercury was thought to be tidally-locked (this was discovered to be untrue in the 1960s)...etc.
The point is, it, more or less by its own admission, is limited to ideas that were already available to humans at the time it was 'revealed'. How then is it 'revelation' at all? And what genuine value could it have to us - except as an increasingly quaint and dated expression of some ideas people had about reality in the early 20th century?
Just like in human society there are rules for angels. The rules don't come from God, God's rules are the rules of physics and they are unbreakable, even for Jesus.
Certain very high level angels have rules that all lower angels must follow. If an angel violates them there are severe consequences, for instance, treason against the universe gets an angel the death penalty, in some cases without a trial. It's instantaneous.
Other rules are formed by lower angels, usually, the leaders of certain groups. Think of it this way, the Electricians Union might have rules against using electrical tape to repair wires, if you violate that rule you are punished by your peers, by other angels, not by God, not by Jesus, and not even by the very high level angels. For something like that it might just be some retraining or an assignment to a different job.
Now, to answer your question, giving new information to God's children is a violation unless it has been approved by Jesus before hand. The reason is because giving new information to humans is reserved for God. When Moses heard a voice in his head, that was God, or more correctly, his soul, which is a fragment of God. When Einstein came up with E=MC squared, that was God. When you lose your keys and then their location suddenly pops into your head, that's God.
So, when the UB says that "we are forbidden to include such humanly undiscovered facts," that's what it means. They can give you the information but they will be in violation. Angels don't just commit violations, other than Lucifer and his rebellion, but that was an extremely rare case.
So, why did they attempt to give us any science information at all? I think what they did is include some truth with some incorrect things. Sometimes, I think they really try to get us to think outside the box.
As for the information it provides about angels and the many universe levels and God and Spirit and Jesus, there is nothing that comes close to giving us as much information.
