Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

Physicists once treated Einstein’s picture of a clockwork universe as the gold standard for what “reality” should look like, ...

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) ...

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.

Quantum invariants have emerged as powerful algebraic and numerical tools that encapsulate the subtleties of topological structures. By drawing on quantum group theory and the constructs of ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

A RECENT GROUNDBREAKING EXPERIMENT in which anesthesia was administered to rats has convinced scientists that tiny structures in the rodents’ brains are responsible for the experience of consciousness ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

ARC Discovery Early Career Research Fellow, The University of Queensland Imagine you sit down and pick up your favourite book. You look at the image on the front cover, run your fingers across the ...

Natalie Paquette spends her time thinking about how to grow an extra dimension. Start with little circles, scattered across every point in space and time—a curlicue dimension, looped back onto itself.

Scientists are like prospectors, excavating the natural world seeking gems of knowledge about physical reality. And in the century just past, scientists have dug deep enough to discover that reality’s ...
