New Codes Could Make Quantum Computing 10 Times More Efficient
Quantum computing is still really, really hard. But the rise of a powerful class of error-correcting codes suggests that the task might be slightly more feasible than many feared.
Quaking Giants Might Solve the Mysteries of Stellar Magnetism
In their jiggles and shakes, red giant stars encode a record of the magnetic fields near their cores.
Math Proof Draws New Boundaries Around Black Hole Formation
For a half century, mathematicians have tried to define the exact circumstances under which a black hole is destined to exist. A new proof shows how a cube can help answer the question.
JWST Spots Giant Black Holes All Over the Early Universe
Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.
Exoplanets Could Help Us Learn How Planets Make Magnetism
New observations of a faraway rocky world that might have its own magnetic field could help astronomers understand the seemingly haphazard magnetic fields swaddling our solar system’s planets.
New Calculations Show How to Escape Hawking’s Black Hole Paradox
Inside of a black hole, the two theoretical pillars of 20th-century physics appear to clash. Now a group of young physicists think they have resolved the conflict by appealing to the central pillar of the new century — the physics of quantum information.
Does Nothingness Exist?
Even empty space bubbles with energy, according to quantum mechanics — and that fact affects almost every facet of physical reality. The theoretical physicist Isabel Garcia Garcia explains to Steven Strogatz why it’s so important in modern physics to understand what a true vacuum is.
How (Nearly) Nothing Might Solve Cosmology’s Biggest Questions
By measuring the universe’s emptiest spaces, scientists can study how matter clumps together and how fast it flies apart.
How Quantum Physicists Explained Earth's Weather Patterns
By treating Earth as a topological insulator — a state of quantum matter — physicists found a powerful explanation for the movements of the planet’s air and seas.
