SCIENTISTS SAY THAT MOON'S SIZE IS GETTING REDUCED. IS THAT SO ?

    ANS: ACTUALLY IT CAN BE SO,THAT  MOON AT THE BEGINNING STAGE OF FORMATION, IS LOOSELY PACKED. (i.e., WE CAN SAY THAT INITIALLY THE MOON'S DENSITY WOULD HAVE BEEN LESSER) .WHEN DENSITY OF ANY OBJECT IS INCREASED, CERTAINLY ITS SIZE (i.e.,VOLUME) WOULD  BE GREATLY REDUCED.HOW CAN THE DENSITY BE REDUCED?     DUE TO ROTATION, REVOLUTION OF THE MOON AROUND THE EARTH FOR SO MANY YEARS AND SETTLING OF DUST,GASEOUS PARTICLES ON IT DURING THESE YEARS WOULD HAVE MADE IT HEAVIER AND SO SIZE WOULD HAVE GOT REDUCED. IF THIS IS TRUE, THEN SURELY SCIENTISTS WOULD SOON FIND A CHANGE OR A SLIGHT INCREASE IN MOON'S GRAVITY SOON.(BECAUSE ONLY IF THE SIZE IS REDUCED IT MEANS THAT GRAVITY HAS INCREASED).
