The latest effort to overhaul math and science education offers a fundamental rethinking of the basic structure of knowledge. But will it be given time to work?
The surprising discovery of a massive, Milky Way–size galaxy that is made of 99.99 percent dark matter has astronomers dreaming up new ideas about how galaxies form.
String theory has so far failed to live up to its promise as a way to unite gravity and quantum mechanics. At the same time, it has blossomed into one of the most useful sets of tools in science.
Just months after their discovery, gravitational waves coming from the mergers of black holes are shaking up astrophysics.
The astrophysicist Tracy Slatyer is searching for faint wisps of dark matter annihilating in the early universe — and perhaps in hiding places closer to home.
Physicists are confronting their “nightmare scenario.” What does the absence of new particles suggest about how nature works?
The physicist-mathematician Miranda Cheng is working to harness a mysterious connection between string theory, algebra and number theory.
A hint that neutrinos behave differently than antineutrinos suggests an answer to one the biggest questions in physics.
The physicist Asimina Arvanitaki is thinking up ways to search gravitational wave data for evidence of dark matter particles orbiting black holes.
According to our best theories of physics, the universe is a fixed block where time only appears to pass.
