For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an ...

The standard model of particle physics works really well, but it can't explain why the universe exists. Something is missing, ...

For decades, a puzzling discrepancy involving a tiny subatomic particle called the muon fueled speculation that physicists might be on the verge of discovering an entirely new force of nature. Now, an ...

Scientists have unveiled a new theory on the birth of the cosmos, suggesting the early universe was shaped by an ancient ...

Is the light from the headlights of a train traveling at the speed of light twice the speed of light?Ranbalral's journey, which began with such a question, has only just begun.Why does light look like ...

It came from deep space, moving at the speed of light, and crashed into Antarctica. Deep below the ice, it met its end. It wasn’t an asteroid or alien spacecraft, but a particle that rarely interacts ...

When trying to answer questions as deep as “what makes up the universe,” advance planning is key. On June 11, the National Academies of Science, Engineering and Medicine announced the result of a ...

Elementary particles are both waves and particles. I learned in Chapter 1 that the wave nature is due to 'field excitation'. It seems the particle nature is also due to 'field excitation'. Me: The ...

WASHINGTON — A new report from the National Academies of Sciences, Engineering, and Medicine presents an ambitious and comprehensive long-term vision for the field of particle physics to further our ...

Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

Here’s what you’ll learn when you read this story: Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing ...
