In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical framework that describes nearly all particles and forces in the universe but ...

Quantum mechanics forms the bedrock of modern physics, describing the behaviour of matter and energy at the smallest scales. Its counterintuitive concepts, such as wave‐particle duality, superposition ...

For nearly a hundred years, every known particle in the universe belonged to one of two camps. Bosons, like photons, can ...

Add Yahoo as a preferred source to see more of our stories on Google. The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and ...

Scientists have pulled off a mind-bending quantum experiment that sounds almost impossible: they showed that tiny metal ...

Quantum field theory (QFT) is a research area in theoretical physics that formulates fundamental interactions in terms of quantized fields defined over spacetime, unifying special relativity and ...

Particles are nature’s smallest constituents, but that doesn’t mean they’re fundamental. So what is the Universe made of?

(Viaframe/Stone/Getty Images) Although our Universe appears to be stable, it might just be in a temporary state of false calm that could rupture in the blink of an eye. We consider a vacuum to be the ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one. In everyday three-dimensional space, that swap only comes in two flavors. Either the ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can ...
