As a scientifically minded individual, it's very clear that there is a limit to imagination. We have a finite brain, contained in a finite volume comprised of finite neurons. From this, we naturally can conclude that there are only a finite number of configurations that these neurons can be in, and thus, a finite number of ideas that can be expressed by even the entire collective of humanity put together. This is more of a natural limitation governed by physical laws, and probably not the philosophical inquiries that you were looking for.
You seem to be correlating a specific brain configuration to a specific idea, but the brain really doesn't store data like that. For example, both Bob and Jane might have a brain configuration in their right anterior lobe which we would describe as an ABFAE configuration. Bob and Jane might also witness the same event. However, Bob might use his ABFAE configuration to store that information; while Jane might be using ABFAE to store something else and so uses DAFAE instead to store that event. And that's before neuroplasticity comes into play.
I'm still with you on the premise, just not sure we can use this description as the proof of it.
I do understand what you are saying, but I am more being a literal stickler, if you will. Even if a brain the size of the universe existed, the properties of that brain are still finite (volume, density, mass, configuration). Jane and Bob, despite using the same configurations or different ones, will witness the same even from different vantage points, and thus always have a slightly different interpretation of these events. You can take into account their vantage points, and then (in theory) place each of them at every possible location in the universe for viewing said events. Eventually, after every possibility is exhausted, they will both, in their respective minds, come to every single possible conclusion about that event.
Now, after doing this, Jane and Bob may still have differing views yet. However, the amount of differing in there views is still finite; you could not get them to come up with any more novel views from which to differ with one another. Complete said theoretical experiment for all 7 billion people on planet Earth, and you would indeed come up with a large number of possible views for any one given event, but a large number is still not infinite. You could have all 7 billion humans view every single event to come from every possible way of viewing every event and you would still only come up with a finite number of interpretations for every single given event viewed from every single possible vantage point. Like I said, I am being particularly picky, but I think in the strictest sense, there is a limit; not that we'll ever reach it, or anything like that.
