The rhythms of the universe, to find them we track their periodicity. Right now, Earth's magnetic field is weakening. But it's not going to go away in anybody's lifetime, so nothing would worry about it. And by the way, there's no evidence of extinction when the magnetic field went to zero and then went back up when it flips. The name of the clueless... They've got fried when the poles flipped. That's what you get for trying to use those legs that you should... You should stay in the ocean now.
What happens if Earth’s core is slowing? Neil deGrasse Tyson and comedian Chuck Nice explore the spinning of Earth’s core, the physics of tire pressure, and the science of toast.
