A week or so ago, I got a question on Facebook that was relayed from one of the kids of a college friend, which I'll paraphrase as "What's the physics explanation of what gives objects their color?" ...

For more than half a century, the idea that light or radio waves could suddenly reverse in time sounded like a thought experiment, not a laboratory result. Now, a series of meticulous experiments has ...

Researchers propose a novel scheme to produce isolated attosecond pulses using relativistic electron mirrors, paving the way ...

A twist in the universe's first light could hint that scientists need to rethink physics. A pair of Japanese scientists looked at the polarization or orientation of light from the cosmic microwave ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

The 2023 Nobel Prize in physics has been awarded to three scientists who created pulses of light so short they can be used to watch the inner workings of atoms. Pierre Agostini, Ferenc Krausz, and ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...

Quantum physics is arguably the greatest intellectual triumph in the history of human civilization, but to most people it seems like it's too remote and abstract to matter. This is largely a ...

While the terms "quantum physics" and "Theory of Relativity" are used casually every day, not many people know what they really mean. Yet these theories have had a profound impact not only on science ...
