For the first time, astronomers have used a ground-based telescope to observe polarized microwave light from the universe's earliest epoch. Their observations could give them a better understanding of ...

The report by the 2023 Particle Physics Project Prioritization Panel – or P5 – lists recommendations for federal funding agencies for what should be constructed to advance particle physics ...

Physicists prove long-held theory light can be made from nothingness of vacuum. Researchers say simulation experiment may pave way to look for dark matter particles ...

Does light behave more like a particle, or like a wave? Today we know the surprising answer. Here's why it took so long to get there. When you purchase through links on our site, we may earn an ...

The scientists have described how they made two individual quantum photons of light interact, ... This research, published in the journal Nature Physics on March 20, ...

By Christian Edwards, Katie Hunt and Ed Upright, CNN (CNN) — The 2023 Nobel Prize in physics has been awarded to a team of scientists who created a ground-breaking technique using lasers to ...

Background light can also leak in, ... In quantum physics, light is treated as discrete particles called photons. These particles maintain some wave-like qualities, including interference.

The Cosmic Microwave Background carries with it a record of events throughout the 13.8-billion-year history of the universe. Just as Charles Darwin once used the fossil record to tell the story of ...
