For the first time, physicists have used lasers to deep-freeze antimatter. In a new experiment, an ultraviolet laser quelled the thermal jitters of antihydrogen atoms, chilling the antiatoms to just ...

Gravitational waves are known disturbances in the fabric of space-time caused a variety of sources, including supermassive black holes, stellar-mass black holes, neutron stars, pulsars, supernova, and ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? A Bose-Einstein condensate (BEC) is a special phase of matter where the atoms combine ...

Conventional lasers produce a coherent wave of light, meaning all of the light vibrates in a synchronized fashion. As described by the wave-particle duality from quantum mechanics, the behavior of ...

According to quantum theory, things like atoms may also be conceived of as waves, and we can technically make 'atom lasers' that comprise continuous waves of matter. The difficulty is in getting these ...

Among his many theoretical insights, Albert Einstein predicted the existence of two phenomena in our universe that have since been proved: gravitational waves and the stimulated emission of radiation.
