Consider the following: we’ve got tides here on Earth, the Moon only shows one face to the Earth, we’ve got volcanoes on Io, and ice geysers on Enceladus. All these phenomena originate from a common cause: the force of gravity stretching across space to tug at another world.
Ep. 42: Magnetism Everywhere
You probably don’t realise it, but magnetic fields are everywhere. We’re not talking about the magnets in your speakers, your electronic equipment or on the fridge door. We’re talking about the gigantic magnetic fields that surround planets, stars, galaxies and some of the most exotic objects in the Universe.
