Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.

Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.

Robots are about to venture into the sunless depths of lunar craters to investigate ancient water ice trapped there, while remote studies find hints about how water arrives on rocky worlds.

Vijay Balasubramanian investigates whether the fabric of the universe might be built from information, and what it means that physicists can even ask such a question.

The Tonga eruption in January was “basically like Krakatoa 2.” This time, geophysicists could explain the tiny tsunamis that cropped up all over the planet, solving a 139-year-old mystery about Tonga’s predecessor.

A new analysis of W bosons suggests these particles are significantly heavier than predicted by the Standard Model of particle physics.

Thanks to the power of fluctuation relations, physicists are taking the second law of thermodynamics to settings once thought impossible.

Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave.

Physicists are devising clever new ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But so far, they’ve seen no signs of exotica.
