The migration model says that all the planets migrate inwards by one orbit periodically, with those who have cores, actually BIRTHING their cores before they migrate. The Earth is soon to literally birth her core at the Weddell Sea in Antarctica. The temperatures down there are starting to rise dramatically now. The ebook explains the model. The end result is that our current moon was previously the core of Venus. Venus currently has no magnetosphere as it has no core. In next migration Earth will birth it's core and move into the orbit of Venus - with the accompanying atmosphere because of its distance from the Sun. Venus and Mercury are to go INTO THE SUN. The Hopi teach that this is the destiny of all the planets in the Solar System as they migrate inwards by one orbit at each "purificaiton". Sounds crazy at first, but not so crazy once you start piecing solar observations together. Anyway read the ebook. It opened my eyes years ago...

Could very well be true there is alot we don't understand about our planet and the solar system. I believe it is the Sumerians who have writings about the time before we had our moon. Might be wrong my dad has been talking to me about aliens and conspiracy theories since I can remember and when I was younger I used to not really pay attention but now I'm all into it. I love ATS and reading what other people think I truely believe if you want to learn anything worth learning you have to do it on your own because our school system are trying to dumb us down and teach us what they want us to know.

.... This doesn't seem to explain the core heat of planets like earth and Venus and previously mars. Now I'm not claiming to be the first but I have never seen this theory presented by any credible sources, well any sources for that matter. If you've seen it before please link it and the thread can be closed.
The energetic impacts of the smaller planetesimals (as well as radioactive decay) will heat up the growing planet, causing it to at least partially melt. The interior of the planet begins to differentiate by mass, developing a denser core

Abstract
The recent theories of planetary formation lead to a gravitationally unstable structure of the proto-Earth in the accretion stage, which is composed of three layers: an innermost undifferentiated solid core, an intermediate metal-melt layer, and an outermost silicate-melt layer. Taking this configuration as an initial state, we investigate the Earth's core formation due to the Rayleigh-Taylor instability by using the quantitative results on the instability in a self-gravitating fluid sphere obtained from another paper (S. Ida, Y. Nakagawa, and K. Nakagawa, submitted). We find that the instability occurs through the translational mode on a time scale of about 10 hr if the thickness of the metal-melt layer 1 km. This leads to the conclusion that the Earth's core began to form through the translation of the innermost undifferentiated solid core as soon as the outer layer was melted and differentiated in the late accretion stage. In addition, we examine the rotational effects of the instability; the translation occurs most often along the rotational axis. But this preference is weak, since the rotational energy is small compared to the gravitational one.
