The theory holds incredible weight because the Fibonacci sequence is already woven into the album's fabric. The syllables in the title track's lyrics famously follow the pattern: "Black [1] then [1] white are [2] all I see [3] in my infancy [5]...". The time signature of the main riff for the song "Lateralus" is also a Fibonacci sequence, alternating between 9/8, 8/8 and 7/8.
Yes. Unequivocally.
