Big Bang

A frame from a simulation of the merger of two black holes and the resulting emission of gravitational radiation (colored fields, which represent a component of the curvature of space-time). The yellow areas near the black holes do not correspond to physi

Listen to the collision of two black holes. Einstein was right.

Science

One hundred years ago, Einstein predicted the existence of gravitational waves. Today, for the first time, scientists announced that they’ve actually been detected. Here’s what the discovery might mean for our understanding of the universe.

Despite the cartoons that her dad draws to illustrate his work — in this case, the theory of cosmic strings — Alina Simone still can't figure it out.

Even when your dad’s a physicist, it’s hard to wrap your head around the Big Bang discovery
