Michelson died with only 36 of the 233 measurement series completed and the experiment was subsequently beset by geological instability and condensation problems before the result of 299,774 ± 11 km/s, consistent with the prevailing electro-optic values, was published posthumously in 1935.
Michelson morreu cando só se realizaron 36 das 233 series de medicións, xa que despois o experimento viuse obstaculizado pola inestabilidade xeolóxica e por problemas de condensación; chegouse ao valor de 299.774±11 km/s, coherente cos valores electro-ópticos prevalentes, que se publicou postumamente en 1935.
