Imagine a juggler tossing balls into the air. The art of juggling is a dance between motion and pause, where the ball’s speed ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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 ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...

Before a beginners’ physics class at St. Louis’ Washington University, Assistant Professor Edward Lambe plugged in an electric device that shot pennies at a metal disk a few feet away. The pennies ...
