You know, the Earth's core as a giant magnetic ball, the shape of it should be rounded, because of gravity. The Sun is not soild right, but how is it possible to be rounded? I mean the inner core contain temperature more than 15 million K, even iron under such circumstance will melt. Never mind let's put it this way, under what situation the gas or energy will become round shape? Does spinning extremely fast would cause a object rounded? What if the object slow down, in that case would the material from the object leak out?

Sorry if I confuse you :)

just gravity makes it rounded.
asteroids are not always round as they have not enough gravity.

if the spinn is increased too much then the gravity will have less effect but this seems to not happen as with most observes objects the faster the spin the greater the mass and the gravity

contains are maintained with the gravitational speed at the centre, the shape of energy as not specifically assume, but the force and power of energy can be count, when energy itself out from the object that energy spread into equal the size when it exit, later it spread and that size can not be count visibly.

could it be because at one time Earth was fluid as a mass. therefore the spinning motion of the early Earth formed the sphere shape?

and that the reason that asteriods are not in a sphere shape is because they are not in a fluid state?

just a query!
