Moroccan rocks reveal that Earth’s magnetic field once changed fast but followed a hidden order, helping scientists map ...

If the magnetic field hadn’t bounced back, Earth might have instead gone the way of Mars. “If the extraordinarily weak field had remained after the Ediacaran, Earth might look very different from the ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...
