ABSTRACT
Humans are taught that the Earth’s day is 24 hours or 86,400 seconds. Scientists have found that there are inequalities on the millisecond level, which might affected predicting weather and earthquakes. The earth day of 24 hours is attributable to the rotation of the Earth around its axis. On the other hand, it takes 3 hours, 56 minutes and 4.0916 seconds for the Earth to turn once on its axis which is identified as sidereal days. The key question is why this seems different post 2004 tsunami?
