Earth's Rotation Slows and Atlas Shrugs
Did you feel the Earth move? Or rather, did you feel it slow a bit under your feet? It has. In what is not quite so cataclysmic an occurrence as one might think, the Earth is experiencing its fourth year of slow down. The rotational speed of our planet is not a fixed thing. The Earth wobbles on its axis, our magnetic poles switch polarities, the amount of solar wind that reaches and reacts with our planet increases and decreases. All these natural phenomena have occurred in the past and will occur again. Right now, it is time for our planet to slow a bit. While this may not mean that buildings are toppling there are still consequences. First, geophysicists do measure the rotational speed of our planet very precisely. The variations occur in milliseconds. That is the minu...
