According to all the known laws of physics, the Big Bang should have created a Universe consisting of both matter and ...

Particle and nuclear physics evokes evokes images of huge accelerators probing the extremes of matter. But in this round-up ...

If an atomic physicist like Nathan Lundblad could slip the surly bonds of Earth’s gravitational pull, what kind of experiment would he dream up? About a decade ago, that very question was posed to ...

The results are an important stress test for theories and future experiments in atomic physics. 1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

In March 2018, researchers launched what looks like a white, cooler-sized fridge to the International Space Station. That heavy box houses a $100 million facility known as the Cold Atom Laboratory, ...

Physicists are learning to treat light not as an untouchable beam that simply passes through matter, but as something that ...

One of the great successes of 20th-century physics was the quantum mechanical description of solids. This allowed scientists ...

While many Earth-based experiments have been run to try to detect dark matter, the mysterious substance remains elusive. Now physicists have proposed a new experiment that would try to find signals by ...
