At −273.15° C (−459.67° F), absolute zero was thought to be the lowest limit of the thermodynamic temperature scale. However, a team of scientists from the Max-Planck-Institute in Germany recently proved this theory wrong. They managed to cool a cloud of gas atoms in a vacuum to below −273.15°C. The result of the experiment was so surprising for the researchers that they did not even know what to do with the chilled particles.
