The S-Matrix Is the Oracle Physicists Turn To in Times of Crisis
Particle physicists in search of the next theory of reality are consulting a mathematical structure that they know will never fail: a table of possibilities known as the S-matrix.
He Seeks Mystery Magnetic Fields With His Quantum Compass
Alex Sushkov is updating an old technology with new quantum tricks in hopes of sensing the magnetic influence of dark matter.
Will Better Superconductors Transform the World?
Scientists are pursuing materials that can conduct electricity with perfect efficiency under ambient conditions. In this episode, the physicist Siddharth Shanker Saxena tells co-host Janna Levin about what makes this hunt so difficult and consequential.
Dogged Dark Matter Hunters Find New Hiding Places to Check
Perhaps dark matter is made of an entirely different kind of particle than the ones physicists have been searching for. New experiments are springing up to look for these ultra-lightweight phantoms.
How a NASA Probe Solved a Scorching Solar Mystery
The outer layers of the sun’s atmosphere are a blistering million degrees hotter than its surface. The hidden culprit? Magnetic activity.
AI Starts to Sift Through String Theory’s Near-Endless Possibilities
Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles — though not yet those of our universe.
Hopes of Big Bang Discoveries Ride on a Future Spacecraft
Physicists and cosmologists will have a new probe of primordial processes when Europe launches the Laser Interferometer Space Antenna (LISA) next decade.
Geometers Engineer New Tools to Wrangle Spacecraft Orbits
Mathematicians think abstract tools from a field called symplectic geometry might help with planning missions to far-off moons and planets.
Can Information Escape a Black Hole?
Black holes are inescapable traps for most of what falls into them — but there can be exceptions. The theoretical physicist Leonard Susskind speaks with co-host Janna Levin about the black hole information paradox and how it has propelled modern physics.
