(Image credit: Eugene Mymrin via Getty Images) From nearly indestructible metals, like tungsten, to delicate clouds in the sky, atoms make up everything around us. But do these atoms ever touch each other? As with most topics in atomic physics, the
Atoms at temperatures beyond absolute zero may be a new form of matter
The temperature of atoms is determined by their energy and entropyagsandrew/Shutterstock A cloud of atoms with a temperature beyond absolute zero – which is also bizarrely hotter than any positive temperature imaginable – could be a mysterious new quantum state of matter. Luca Donini at the University of Cambridge and his colleagues have put thousands
