The Past Earth's Rotation | | A. I. Arbab
; | | Date: |
25 May 1999 | | Subject: | General Physics; Geophysics | physics.gen-ph physics.geo-ph | | Abstract: | We have proposed a model to obtain the length of the day and month at any geologic time. The day is found to increase by 0.002 sec/century since the seventeenth century. The lengthening of the day is attributed entirely to the increasing gravitational constant ($G$) with time that manifested its self in tidal forces. The data obtained are consistent with those found from Palaeontology. The length of the day 4500 million years ago was 6 hours and the synodic month was 56.26 present epoch days. | | Source: | arXiv, physics/9905049 | | Services: | Forum | Review | PDF | Favorites | |
