Of course that’s just as valid as any other theory, in my opinion. I guess I was just pointing out that given the theory of ‘finite lengths of civilization’s exploring capability’ is universally correct, this limit might be shorter or longer relatively. It’s hard to say that most high tech civilizations only last 100,000 earth years or whatever it might be, when the average life span of some species could be 100,000 earth years.

I believe that a people lasts until it destroys itself, or at least destroys its ability to do anything “off planet”.
It’s almost like a self destruct mechanism, or a governor on a car.
