This is the clumping together of tiny grain sized particles of rock and ice that were orbiting the sun. As these particles collided, they formed larger clumps which eventually collided and got bigger and bigger.
After some time, the size of these planetesimals became large enough that there was enough gravity to pull them together rather than just colliding by blind chance. The largest probably pulling the smaller bodies towards it. As this planetoid gets larger and more smaller bodies collide with it, it melts from the vast amounts of heat created by each collision.
Could this be true?
The final step is differentiation of the planet where the heavy objects sink and the light objects float. This gives Earth its heavier iron-nickel core (which causes a magnetic field for those of you keeping score) and lighter oxygen-silicon crust.
When all that is done, radiation of heat occurs which allows the planet to cool from the outside in thus causing a solid crust to form.
It is believed that any molten planetoid of a size greater than about 310 miles (500 km) has sufficient gravity to cause gravitational separation of light and heavy elements thus producing a differentiated body. The Earth, at around 8,000 miles in diameter, is about 25 times this required size. Therefore, it definitely would have been molten and gone through the differentiation process.
The only possibility to form a hollow planet would be if the planetesimals were in exactly the right locations to have come together in a hollow shape in the first place."
Damn, pesky old science debunks yet another crackpot theory (IMG:
