So, let's do a little experiment. Let's say we reverse Earth's rotation. What then? Well, you'll change a lot more than just the sunsets. This may seem like a ridiculous scenario at first.

As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching the ...

As well as a few temporary reversals, the Earth's magnetic field – just like the Sun – can flip over long timescales. During the Brunhes–Matuyama reversal, the magnetic north could have been ...
