A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

A physicist proposes that consciousness is the fundamental basis of reality, with matter and spacetime emerging from it.

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Henry Yuen is developing a new mathematical language to describe problems whose inputs and outputs aren’t ordinary numbers.

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

Appearance is one thing, but reality is another. The world does not appear to be a hologram, but maybe it is. Thus begins physicist Leonard Susskind in opening a doorway between science and religion ...

In July 1925, physicist Werner Heisenberg wrote a letter to Wolfgang Pauli sharing his new ideas about what would eventually become known as quantum theory. A hundred years later, that theory has been ...

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to launch pads but by probing the strange limits of quantum theory. A new ...

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 ...

Some researchers believe consciousness is a byproduct of the constantly firing web of neurons in our heads. However, others believe something more theoretical must be involved to explain our complex ...
