Relativity II

subjectively, a century's ticked past
since Einstein published relativity
coordinates can't but conform to mass
attested by the path of Mercury
the laws of Newton just approximate
the special case where space-time's nearly flat
but Albert Einstein dared to formulate
the broader rules regardless where one's at
a rippling mollusc undergirds his grid
in non-Euclidean geometry
complexity can no longer stay hid
in contemplating space-time at high 'g'
no rail embankment's constant as a rock
by which to calibrate measuring sticks
and now Lorentz has smashed our very clock
the rest can change and only 'c' is fixed
yet fuzziness still dogs the smallest size
until we know if gravity's quantized
