The Earth’s magnetic field may flip every few thousand years due to lopsided growth of the planet’s core. Scientists investigating the phenomenon of magnetic field reversal have determined that these shifts are likely to be connected to the growth of the core. The findings also suggested that the next reversal could be underway and that if this happens it could prove disastrous for power grids and communications systems. “What we found that is interesting in our models is a correlation between these transient [shifts] and reversals [of Earths magnetic field],” said Peter Olson of Johns Hopkins University. “We kind of speculate there is that connection but the chaos in the core is going to prevent us from making accurate predictions for a long time.” NSHere’s to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes… the ones who see things differently — they’re not fond of rules… You can quote them, disagree with them, glorify or vilify them, but the only thing you can’t do is ignore them because they change things… they push the human race forward, and while some may see them as the crazy ones, we see genius, because the ones who are crazy enough to think that they can change the world, are the ones who do. — Steve Jobs, US computer engineer & industrialist.
