For decades, researchers have toyed with antimatter while searching for new laws of physics. These laws would come in the form of forces or other phenomena that would strongly favor matter over ...

An artistic illustration of the movement of an antihydrogen atom in the ALPHA magnetic trap, before (grey) and after (blue) laser cooling. The images show various lengths of the antihydrogen's track. ...

The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves. These waves are caused by colliding ...

Absolute zero − the most appropriate temperature for both quantum experiments and quantum computing − makes it easier to describe a system by relying on a set of fundamental propositions. One of them, ...

How would you go about determining absolute zero? Intuitively, it seems like you’d need some complicated physics setup with lasers and maybe some liquid helium. But as it turns out, all you need is ...
