Has a Korean quantum research group cracked the holy grail of physics, an ambient temperature and pressure superconductor that will win them a Nobel prize and change humanity forever? Probably not. Dave completely busts the demo video of their LK-99 material with a pracitcal lab example, it’s such an embarrassing …
