Let’s go on a journey of discovery to the center of our Milky Way Galaxy. We are going to watch a planet being formed. It will take us a few million years so you must be prepared to be patient. It begins with a stray lump of Magnetite that was once part of a Sun that exploded. As it moves through space it’s magnetic properties attract any stray pieces of Iron that is also part of the flotsam and jetsam floating around in the Milky Way Galaxy. Since the lump of Magnetite was in a molten state the iron melts and becomes part of its mass. The more it attracts the larger it grows and the more it burns. But this piece of Magnetite also has another property it can lay claim to. It can also repel certain metals. And since there is much flotsam and jetsam from other suns that went nova that contain other metals as well as iron a form of strange battle begins to take shape around our lump of Magnetite. It depends on the ratio of iron to the other metals weather this lump will be attracted to our core and adhere to it or be held off at a distance. As our initial core of Magnetite goes on its journey through space collecting bits and pieces of iron and repelling lumps of iron that contain morecopper and silver and gold and other rare metals, these begin to form an outer shell around our burning core preventing any more growth of the core but continuing to attract other debris if it contains any irons. It would depend on the ratio of metals. One
metal would be attracted and the other repelled so it would depend on the
ratio of the content of metals whether the debri joined the core or was held
at a distance.
While all this was going on, the inner molten core was spinning on it’s axis and this was creating a vortex at the top and bottom of the spin, which in turn would have prevented debris from forming a wall within the vortex. In other words you would have two empty area’s top and bottom of the spin.
As this mass of the outer shell grew in size, any area of the shell that managed to attract a large chunk of rock with a lot of Iron in it or other metals that would be attracted by the core would probably create tunnels or holes in this shell as it fought it’s way to the central core. In the beginning of this type of planetary creation there may have been many times that the outer shell was torn apart or shattered. But the very nature of this construction over vast periods of time would have adjusted itself to a settling and consolidation. This would account for the difference in size of all the planets and, in a way, for the structure of the Sun itself.
Even today this planet Earth keeps building inch by inch as debris falls down upon its surface. One can explain the different layers of the earth by this method where pressures and heat build up within certain areas or where faults have shifted the matter of the outer layers or where compacting is occurring still in the outer layer.
If there was a distance created between the core or inner sun, and the outer layer of repelled matter, and you had an opening created by the vortex at each end of the same vortex then you would have access to oxygen from the surface. And since we do not have any true idea of where plant life springs from we cannot say for sure that the hollow within the earth would be barren of life any more than the outer shell. And since we have no true knowledge of how or where life comes from we cannot say for certain that life could not exist within this hollow area.
If fact any hollow area on or within the earth is probably capable of hosting a life form. And a sun is a sun even if it is small and gives off a different light. It is a form of energy that may be capable of supporting life forms weather of plants or animals, including human beings. The forces that create and sustain life are really unknown to us. Where life comes from is also basically unknown to us.
