Negative Temperatures That Are Hotter Than the Sun
Scientists have cooled potassium gas to one billionth of a degree below absolute zero. But in the quantum world, that’s actually hotter than the Sun. It’s hotter, even, than infinity degrees Kelvin. Vladan VuletiÄ‡, a quantum physicist at MIT, talks about this ‘Bizarro World’ temperature.
