Scientists have rewritten the known laws of physics after hitting a temperature lower than absolute zero. Physicists at the Ludwig Maximilian University in Germany created a quantum gas using potassium atoms, fixing them in a standard lattice group using magnetic fields and lasers. When the magnetic fields were rapidly adjusted, the atoms shifted from a low energy state to their highest possible energy state. That rapid transition — along with the laser trapping field that kept the atoms in place — allowed the temperature of the gas to dip "a few billionths of a Kelvin below absolute zero."
