explain the theory of everything
that can be any length, so the theory would look different at each length. there is no upper limit on the length of the theory. so indeed the only non-arbitrary choice for a fixed value for the length of the theory would be zero. this unfortunately seems like it's leaving out a lot of possibilities. the second most non-arbitrary choice for the length of the theory would be 'infinitely' long. which actually shares the same problem as a zero-sized theory, in that it lacks any specific discernable detail. so indeed, anything will eventually lead every possible other thing, in due time, in a natural order that may or may not surprise even itself. enjoy
