Which theories for “the great silence” are currently testable? Which ones currently prove or disprove anything?

This theory is at least evidence based. If you’d like to know how it specifically differs from a specific theory, I’m happy to explain just like below.

The way it differs from some god or faeries preserving humans is that;

• it doesn’t require the entity to know or care about us specifically. It does not revolve around our existence
• it fits the observable evidence instead of dismissing it or excusing it or coming up with fantastical, unfounded, "magics"
• it is a logical conclusion for any thinking matter that can consistently improve but is still computationally constrained to our universe, to preserve novelty for the sake of “unknown unknowns” that cannot be computationally discovered
• it follows a proven pattern of increasing information density that can be traced back to the beginning of the existence of any thinking matter. It is the logical conclusion of the physics of that process as we have observed it in the historical record, playing out over several billion years, anywhere in the universe
