Yesterday I watched Isaac Arthur's video about dark matter technologies so today I decided to watch his video about clarketech. Named after the author Arthur C. Clarke, clarketech is an umbrella term for any technology which operates outside the bounds of known physics. Perhaps physical constants can be altered or there are exceptions to the physics laws that haven't been discovered yet.
Examples of clarketech include anti-gravity, perpetual motion machines, faster than light travel, ect. It's fascinating to think about and imagine tecnology that is "indistinguishable from magic".
