    The Ether/Aether

    That there is an invisible structure all around us that allows gravity, light and electricity to move through it. Now debunked or replaced.

    Trepanning to release evil spirits.

    Drill a hole in your head as a cureall for any mental behaviour abnormalities. Still practised as an emergency surgery, only to release life-threatening blood and pressure buildup inside the cranial cavity.

    Blowing smoke up your ass

    Gut pain? Almost drowned? Time to blow some tobacco smoke up your bum. Discontinued.

      Fun fact: This is also how Ethernet (wired network connection) got its name. Ether was already dismissed as a theory, but “omnipresent, completely-passive medium for the propagation of electromagnetic waves” was a good description of hardware layer that can transfer data in a way that’s abstracting all the signal handling complexity for higher layers.

      So in a way I’m actually sending this comment via Ethernet.
