Physics

For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical?

Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics.

Astronomers have found a background din of exceptionally long-wavelength gravitational waves pervading the cosmos.

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.

By treating molecules as geometric tessellations, scientists devised a new way to forecast how 2D materials might self-assemble.

Wave-science researcher Ton van den Bremer and Steven Strogatz discuss how rogue waves can form in relatively calm seas and whether their threat can be predicted.

By measuring inflated helium nuclei, physicists have challenged our best understanding of the force that binds protons and neutrons.

The marine geochemist Chris German brings decades of experience studying seafloor hydrothermal vents to NASA’s preparations for visits to other ocean worlds in our solar system.

The puzzling behavior of black hole interiors has led researchers to propose a new physical law: the second law of quantum complexity.
