It was an old idea of Stephen Hawking’s: Unseen “primordial” black holes might be the hidden dark matter. A new series of studies has shown how the theory can work.
Renormalization has become perhaps the single most important advance in theoretical physics in 50 years.
Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?
Having solved a central mystery about the “twirliness” of tornadoes and other types of vortices, William Irvine has set his sights on turbulence, the white whale of classical physics.
Push or crush a new class of materials, and they’ll undergo record-breaking temperature changes.
Physicists have identified an algebraic structure underlying the messy mathematics of particle collisions. Some hope it will lead to a more elegant theory of the natural world.
Claudia de Rham showed how theories of “massive gravity” could potentially get rid of the need for dark energy.
An 18th-century physicist first predicted the existence of a chorus of atmospheric waves that swoop around Earth. Scientists have finally found them.
Professional astronomers may not point their telescopes by hand anymore, but COVID-19 has still closed observatories and impeded research.
