### The Search for What Shook the Earth for Nine Days Straight

Last year, an immense but brief outburst of seismic energy was soon followed by a long hum that made the world ring. Finding its cause took 68 scientists and an assist by the Danish military.

### Can Thermodynamics Go Quantum?

The Industrial Revolution brought us the laws of thermodynamics, and new ideas about work, energy and efficiency. In this episode, co-host Steven Strogatz speaks with theoretical physicist Nicole Yunger Halpern about what these concepts might mean in the age of quantum mechanics.

### How the Higgs Field (Actually) Gives Mass to Elementary Particles

In this article adapted from his new book, "Waves in an Impossible Sea," physicist Matt Strassler explains that the origin of mass in the universe has a lot to do with music.

### Do We Need a New Theory of Gravity?

Since Newton had his initial revelation about gravity, our understanding of this fundamental concept has evolved in unexpected ways. In this week’s episode, theoretical physicist Claudia de Rham and co-host Janna Levin discuss the ways our current understanding of gravity needs to continue to evolve.

### Computer Scientists Prove That Heat Destroys Quantum Entanglement

While devising a new quantum algorithm, four researchers accidentally established a hard limit on entanglement.

### Mathematicians Prove Hawking Wrong About the Most Extreme Black Holes

For decades, extremal black holes were considered mathematically impossible. A new proof reveals otherwise.

### Diminishing Dark Energy May Evade the ‘Swampland’ of Impossible Universes

The largest-ever 3D map of the cosmos hints that the dark energy that’s fueling the universe’s expansion may be weakening. One community of theoretical physicists expected as much.

### The Webb Telescope Further Deepens the Biggest Controversy in Cosmology

A long-awaited study of the cosmic expansion rate suggests that when it comes to the Hubble tension, cosmologists are still missing something.

### The Geometric Tool That Solved Einstein’s Relativity Problem

Tensors are used all over math and science to reveal hidden geometric truths. What are they?
