I heard an interesting proposal - it sounds plausible but I'm here to see what you guys think. It is a way of explaining a diverse set of natural phenomena on Earth with one mechanism - rotation. The proposal is this: The core of the Earth rotates in the opposite direction to the Earth's mantle creating great heat and energy through friction. This simple mechanism (opposing rotation) is the cause of the heat at the core, the magnetic field around the earth, the auroras, the energy source for life on Earth and gravity. The Earth acts like it has a spinning bar magnet at its centre - perhaps it does. The opposing rotation of the core would explain the consistency of the Earth's magnetic field over time, which has been a problem to explain. The auroras are caused by output of energy at the poles - like a spinning bar magnet. Rotation may also explain the 1400 miles of magma surrounding the core. Our core is the size of our moon and if it spins in the opposite direction, then perhaps it could melt that huge quantity of rock. And act as an incubator for the development of life on Earth. The proposal states that energy produced by the opposing rotating core is electromagnetically attracted to the sun - these two dynamos interact to create the atmosphere on Earth. Gravity is not a force from above pushing down on us, but rather a force from below (the Core) rising up through us towards the sun. We are held in place by the energy winding us through our DNA - the rising energy holds us like screws on a spinning tyre in which the spin ensures the hold. The 'life force' of the planet - that which makes seeds grow and our hearts beat is an explainable force - the energy from the core rising up through us be electromagnetically attracted to the sun. I've given a very brief overview of the proposal, but I hope it's enough to get your ideas flowing. What do you think? Is it plausible? Song and Richards found that core rotates independently from the mantle. They determined it was 1 degree faster, other researchers have said anything from .2 to 3 degrees faster. Sharrock and Woodhouse looking at the data found that the core rotation is best explained as going 'west to east' - opposite to the mantle but they didn't pursue this finding any further. I like this explanation because just one simple mechanism - rotation - can explain how life can develop and be sustained on Earth. It also explains the Earth as a natural system. We see that life on Earth works through systems - interconnected and interdependent. This is also true at a molecular level - so why not at a planetary level? Rotation is a common feature in the cosmos. And just by spinning the core in the opposite direction, you can create many of the necessary conditions for life. What do you think?
