Researchers used a novel, high-precision laser spectroscopic experiment to measure the internal vibration of the simplest molecule. This allowed the researchers to investigate the wave character of ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...

Last year scientists detected gravitational waves from what appeared to be the most massive black hole collision ever recorded. But now an international team of astrophysicists has proposed an exotic ...

Using a highly coherent positronium beam, the researchers observed clear diffraction patterns after transmission through a graphene film, confirming its wave-like behavior. One of the discoveries that ...

Gravitational wave astronomy is starting to do more than confirm Einstein’s equations. It is turning into a precision tool for mapping the invisible, with theorists now arguing that ripples in ...

Evidence is growing for an ultralight dark matter particle called the axion. A study of light warped by galaxies has shown that it is better explained by axion dark matter than weakly interacting ...
