The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

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 ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

The collapse of the quantum wave function – in which quantum objects go from existing within many possible states at once to settling into a concrete one understood by classical physics – does not ...

The National Science Foundation (NSF) has awarded $18 million to nine teams of engineering-led, interdisciplinary researchers to break the conventional ways in which light and acoustic waves propagate ...
