very true.
there is a priciple of physics which is known as entropy.according to this principle disorder (e.g in universe) remains constant or it increases .thats y distance of earth from the sun is decreasing day by day.
so if v take this statement THAT SUN WILL APPEAR FROM WEST in context of entropy than this statement is absolutly correct.
