Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new ...

Auroras, shimmering bands of light that shoot through the night sky near the Earth’s poles, can follow patterns known as arcs ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as ...

Why do light bulb filaments slowly disappear over time? 💡 This video explores the physics behind evaporating light bulb filaments, explaining how high temperatures, material properties, and atomic ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

One of the brightest stars in the night sky will vanish as seen from North America and Europe in a rare event.

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

Lensing in action: A montage of eight time-delay gravitational lens systems. There is an entire galaxy at the centre of each image, and the bright points in rings around them are gravitationally ...
