    "abstract": "We have found an empirical law for the variation of the length of the Earth\u0027s\nday with geologic time employing Wells\u0027s data. We attribute the lengthening of\nthe Earth\u0027s day to the present cosmic expansion of the Universe. The prediction\nof law has been found to be in agreement with the astronomical and geological\ndata. The day increases at a present rate of 0.002 sec/century. The length of\nthe day is found to be 6 hours when the Earth formed. We have also found a new\nlimit for the value of the Hubble constant and the age of the Universe.",
