Plenty Of Space
The transition from one momentary state to another is a momentary state by itself. Interaction between two things is a thing of its own. In its own space, which, like any other space, does not pass.
Spaces do not have to pass, they do not displace one another, but rather superpose each other, penetrate mutually. There is plenty of space in the space of knowledge, enough for all of them.
So knowledge can exist forever, as space, which, the moment it is activated, generates the corresponding things.
