pi lightseconds = the middlemost wavelength mode possible in our observable universe

TSDU:
the shortest possible wavelength is the Planck length 16.163618e-36 meters
the longest possible wavelength is universe length 92 billion lightyears
92Gly = 16.163618 * 10^-36m * 2^290.772
the halfway "mode" of this range is
= 16.163618 * 10^-36m * 2^(290.772 / 2)
= 9.42075 * 10^8 m
= pi * 2.998 *10^8 m
= pi lightseconds

any other neat numerical "coincidences" you've found?
