Scientists have created an artificial intelligence tool called SCIGEN that can potentially speed up the hunt for novel ...

The true “informational age” of the cosmos may be 62 billion years, not just the 13.8 billion years of our current expansion.

Nature has many rhythms: the seasons result from Earth's movement around the sun, the ticking of a pendulum clock results ...

Quantum computers may solve problems beyond supercomputers. A new test helps confirm quantum answers for errors.

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...

In 1931, Harvey Elliott White developed a device that traced out the shapes of electron clouds by approximating solutions to ...

New study proposes using atomic clocks to probe the intersection of quantum mechanics and general relativity in spacetime.

There’s one kind of program that we don’t understand – even in principle – and that’s an AGI. One day we will, but I see no ...

Physicists construct theories to describe nature. Let us explain it through an analogy with something that we can do in our everyday life, like going on a hike in the mountains. To avoid getting lost, ...

A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated ...

What happens when matter transitions from one phase to another—a solid to a liquid or a liquid to a gas? Describing these critical points precisely, in solvable mathematical terms, is no simple feat.
