The "physics" that I needed to mean there was the body of *known* valid physical principles. That is, more precisely, known and "believed" by us. If something true is not generally believed, it is somewhat equivalent to it not being known, true?

homer:"As 'we' evolve, information becomes accessible through a series of discoveries that are accessed through illumination - a source of perception that is un identified. "

Which would tend to underscore that the total summation of knowledge may just be a fixed quantity? Your use of the word "source" we may need to agnostically admit, is an assumption.

Wryly, I speculate that "life" if it "evolves", has "already" been "there" before. Haha.
