It's not the end of the world, but there could be some changes.
According to NASA, the Earth's magnetic poles are due for a shakeup, one that could prompt them to flip 180˚. I know, this sounds bad. First things first–and this may sound supremely obvious or very reassuring based on your level of knowledge on the subject–the flipping of the magnetic poles will not result in any of the following:
A. A chain eruption of the world's volcanoes
B. Massive earthquakes and tsunamis
C. A complete technological breakdown a la Y2K
