Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of ...

Space and time looked settled, at least in broad outline. Einstein’s special relativity gave physics a durable framework for ...

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 ...

Quantum field theory says true nothingness doesn’t exist; even a vacuum teems with energy fields that help create matter and ...

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 theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

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 ...

Here’s what you’ll learn when you read this story: String theory—the idea that particles are not point-like, but instead one-dimensional strings—is a popular theoretical framework that attempts to ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than others. Reading time 5 minutes For all practical purposes, the Standard ...

Noncommutative quantum mechanics extends the standard quantum framework by introducing non-vanishing commutators between position and/or momentum coordinates, thereby modifying the structure of phase ...
