For over 50 years, physicists have generally agreed that the interactions between elementary particles are governed by four fundamental forces: the strong force, weak force, electromagnetic force and ...

Some physicists believe that a fifth fundamental force could be the cause of some observational anomalies. A study is investigating ways to closely examine the trajectories of well-documented ...

The ion of the hydrogen molecule is ideally suited for making ultra-precise measurements of important physical constants.

From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...

The Standard Model of Particle Physics accounts for four fundamental forces—strong, weak, electromagnetism, and gravity—but for decades, scientists have wondered if an elusive fifth force might be at ...

We have long taken it for granted that gravity is one of the basic forces of nature–one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

We know magnetism as a fundamental force of nature that plays a crucial role in both the natural world and modern technology. It governs the behavior of materials at the atomic level and is essential ...

Here’s what you’ll learn when you read this story: Some physicists believe that a fifth fundamental force could be the cause of some observational anomalies. A study is investigating ways to closely ...
