lets tk it other way.. wt if earth starts spinning faster, say double of its speed, at its axis..?? wt will be the result..?!! well well simply it must take 12 hrs then to complete its one spin at its axis..
does it really matter anything.. well yes sudden chng in speed of rotation would obviously matter bt if its speed is such faster then it would be a usual for life n system tht prevails on the earth.
earth n other planets revolve around sun along their specified orbits.. all those planets need to be spinning around their axis to have forward movement along their orbit in order to complete the revolution. some planets are bigger n others smaller.. those who are bigger they tk longer earth time, around 26 to 40 earth hours, to complete one spin around their axis tht means their day is of 26 to 40 earth hours.. in the same manner if earth starts rotating faster or slower around its axis, day would be either smaller or greater than present day earth hours, however, it never mean earth would start rotating faster along its orbit.. no but haha thts funny... well i guess i should then revolve faster or slower along its orbit as well, oop tht would certainly devastate the whole solar system because wt i kno all planets move at uniform speed along their orbits..
God is great architect.. He certainly has done wts the most feasible for our earth n whole solar system.. small days or longer ones must hv wrond impact on lives n environment thts why present day system bn prevailing.. lets leave it the way it is... hehe i am exausted.. cant realy measure as to wt can b the consequences after such an above suppostion.. haha thts funny!
