The way particles interacted while the universe was forming seconds after the Big Bang could explain why the universe exists the way it does – a physicist explains matter-antimatter asymmetry.
A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Researchers have found a way to speed up the search for dark matter using technology from quantum computing. By squeezing quantum noise, detectors can now look for axions twice as fast.
Field theory describes the universe as energy flowing along unending lines. With this perspective, it is possible to define a new fundamental building block of matter.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
The movies make it seem like someday we’ll be able to make people and objects grow really big or shrink really small. Whether this will be possible comes down to the smallest of things.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.
One of the great mysteries of the universe is why there is so much more matter than antimatter. Now a new experiment is helping us understand the nature of antimatter better than ever before.
Forget solid, liquid, gas. This research used advanced math to theorize about topological phases of matter. And over the years experiments with matter and cold atoms have been validating the ideas.
