Is there a maximum temperature?

All particles vibrate – and the more energy they have, the more they vibrate. We experience this as heat, which we measure with temperature scales. Nobody really knows if there is a maximum temperature, as it has never been reached. Some scientists suggest the Planck temperature of 1.41679 x 1032 Kelvin may be the hottest possible temperature as, according to Max Planck, above that the laws of physics stop working. However, in theory, there could be no limit to how hot something can get.
