Physicists have created a quantum gas capable of reaching temperatures below absolute zero, paving the way for future quantum inventions. 'This suddenly shifts the atoms from their most stable, lowest-energy state to the highest possible energy state, before they can react,' said Ulrich Schneider of the Ludwig Maximilian University in Munich to Nature. 'It's like walking through a valley, then instantly finding yourself on the mountain peak.' Moving into the sub-absolute zero realm, matter begins to display odd properties. Clouds of atoms drift upwards instead of down, while the atomic matrix's ability to resist collapsing in on itself echoes the forces causing the universe to expand outwards rather than contracting under the influence of gravity.'This may be a way to create new forms of matter in the laboratory.'
