Scientists have claimed to make a breakthrough that would be “one of the holy grails of modern physics” – but experts have urged caution about the results.
In recent days, many commentators have become excited by two papers that claim to document the production of a new superconductor that works at room temperature and ambient pressure. Scientists in Korea said they had synthesised a new material called LK-99 that would represent one of the biggest physics breakthroughs of recent decades.
