Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always ...

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

FOR an experiment designed to help us find evidence of other universes, it looks surprisingly modest. As Zoran Hadzibabic walks me into the lab, it feels more like a classroom, complete with linoleum ...

So, what exactly is quantum theory in physics? It sounds super complicated, right? Like something only geniuses ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.
