The Hollow Earth...................?

Tell me your understanding of how planets become hollow. If you do not think the earth is hollow, tell me how it formed the way it is now. Thanks.

The Earth is not hollow. It is composed of layers, the crust, the mantle, outer core, and inner core."The Earth is made of many different and distinct layers. The deeper layers are composed of heavier materials; they are hotter, denser and under much greater pressure than the outer layers. Core: The Earth has a iron-nickel core that is about 2,100 miles in radius. The inner core may have a temperature up to about 13,000°F (7,200°C = 7,500 K), which is hotter than the surface of the Sun. The inner core (which has a radius of about 750 miles (1,228 km) is solid. The outer core is in a liquid state and is about 1,400 miles (2,260 km) thick. Mantle: Under the crust is the rocky mantle, which is composed of silicon, oxygen, magnesium, iron, aluminum, and calcium. The upper mantle is rigid and is part of the lithosphere (together with the crust). The lower mantle flows slowly, at a rate of a few centimeters per year. The asthenosphere is a part of the upper mantle that exhibits plastic properties. It is located below the lithosphere (the crust and upper mantle), between about 100 and 250 kilometers deep.""In the very beginning of earth's history, this planet was a giant, red hot, roiling, boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. As the cooling continued, water vapor began to escape and condense in the earth's early atmosphere. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas. It is theorized that the true age of the earth is about 4.6 billion years old, formed at about the same time as the rest of our solar system."

Planets do not become hollow (that goes for the Earth as well).The mass of any object the size of an asteroid or larger (which includes all the planets and the moons) is too great to allow any hollow or open spaces within the object.

Planets including the earth are not hollow. they are formed by asteroids that collide and come together and then that collides with another and so on and so on.as they get bigger or when they get big enough, the earliest rocks to collide (which now for the core of the "ball") start to get hotter and hotter, start to "boil", this = magma which finds it's way to the surface when it finds a crack or way up example volcanoes.planets are not hollow

Think of a spinning bucket with water in it and how the water undergoes concavity and climbs the walls. Then think if the water suddenly froze.
