Are you just saying the length of the rod can be variable along with the position of the notch? If so, it seems like that means you approximately square the number of possibilities, so if there was a maximum of 25 bytes, then there is an maximum of 50 bytes available in something the width of the universe. Still not large.
Your comment is a non-sequitor; reread what he said.
He's saying that there exists a certain ratio in the set of ratios whose decimal representation represents a corpus of knowledge, in this case the entirety of human knowledge.
How did you not get that the term '25 bytes' is merely the size necessary to store the number of possible ratios instead of any actual information?
Did no one read the discussion below about encoding information into pi? This is the same concept. Yes, there are only 25 bytes worth of ratios to chose from, but those ratios themselves can, possibly, POSSIBLY, store all the information.
