Metal undergoes novel transition under extreme pressure
The precise chemistry of metals within the Earth's interior will dictate the nature of its magnetic field Under extreme pressures and temperatures, one of the main materials of the Earth's interior has exhibited a never-before-seen transition.
Iron oxide was subjected to conditions similar to those at the depth where the Earth's innermost two layers meet.At 1,650C and 690,000 times sea-level pressure, the metal changed the degree to which it conducted electricity.
But, as the team outlined in Physical Review Letters, the metal's structure was surprisingly unchanged.
The finding could have implications for our as-yet incomplete understanding of how the Earth's interior gives rise to the planet's magnetic field.end quote from:http://www.bbc.co.uk/news/science-environment-16265510
It might be that these sorts of studies would also give us some clue as to how black holes are formed. It could be said that planets like ours are sort of like Suns that cooled down enough to form a crust, since they are molten just below the crust. So, it is possible from studying what happens at earth's core we will also find out more how and why Black holes form from collapsed suns. For example, what is the difference between a planet and a collapsed sun? Why do they behave differently during their changes? And under what circumstances could man create a black hole on purpose or by accident on earth? And if we can create a man made black hole, can we also create a small man made sun made of hydrogen that would constantly be turning itself slowly from hydrogen to helium to various other elements down the line. If a man made sun, for example could be created and stabilized then we would have a potentially infinite or close to infinite power source here on earth even if the sun were gone. In fact if we could create a small sun at a distance of say the moon we as a planet might be able to move throughout the galaxy with our own sun without our regular sun with our planet as our spaceship. This would be useful if our sun(of the solar system) was going to blow up or cause humans and life on earth some problems in the future.
