Particles are the smallest things we've found, but that doesn't make them fundamental. A deep dive into why the question of what reality is made of remains stubbornly, fascinatingly open.

Flying to Mars means navigating without trees, wind, or GPS. Here's the surprisingly elegant physics behind how spacecraft measure their own velocity in the void.

A speculative spacecraft journey near the speed of light reveals that time dilation isn't science fiction—it's physics. And it's asking us harder questions than we expected.

German researchers propose a fourth theory to explain ice's slipperiness, challenging centuries of scientific debate about pressure, friction, and surface melting.

Physicists 3D-print ice at room temperature, unlocking a new paradigm in energy-free microfabrication with implications for medicine and manufacturing.
