Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

A South Korean physicist has proposed a theoretical framework that could support the unification of quantum mechanics and the ...

God does not play dice with the universe,” Albert Einstein famously declared in 1927, sparking one of the most enduring ...

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 ...

Teleportation via the internet sounds like science fiction. Still, researchers have now demonstrated quantum teleportation ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

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 ...

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.

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...

In the deadly game Russian roulette, a player loads a gun with a single bullet, spins the cylinder to randomize the bullet’s position, and turns the potentially lethal weapon on their own self. But in ...
