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.
The Physicist Who’s Challenging the Quantum Orthodoxy
For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical?
A New Map of the Universe, Painted With Cosmic Neutrinos
Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics.
An Enormous Gravity ‘Hum’ Moves Through the Universe
Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos.
What Can Jellyfish Teach Us About Fluid Dynamics?
Jellyfish and other aquatic creatures embody solutions to diverse problems in engineering, medicine and mathematics. John Dabiri, a fluid dynamics expert, talks with Steven Strogatz about what jellyfish can teach us about going with the flow.
