High-temperature superconductivity

High-temperature superconductivity is a special type of energy flow that happens when things get very cold. It means that energy can move through a material, like electricity, with almost no resistance. That means that energy, like electricity, can move extremely quickly without getting weaker over long distances. High-temperature superconductivity only happens very close to absolute zero temperature, which is about -273 degrees Celsius, colder even than the coldest stuff in outer space. It's like a super-efficient tunnel for electricity, allowing it to travel much further and faster than ever before!
