The world around us is made up of particles invisible to the naked eye, but physicists continue to gain insights into this mysterious realm. Findings published in Physical Review C by Osaka Metropolitan University researchers show that the nuclear structure of an atom likely changes depending on the distance the protons and neutrons are from the center of the nucleus.
In day-to-day life, light seems intangible. We walk through it and create and extinguish it with the flip of a switch. But, like matter, light actually carries a little punch—it has momentum. Light constantly nudges things and can even be used to push spacecraft. Light can also spin objects if it carries orbital angular momentum (OAM)—the property associated with a rotating object's tendency to keep spinning.
Time's inexorable march might well wait for no one, but a new experiment by researchers at the Technical University of Darmstadt in Germany and Roskilde University in Denmark shows how in some materials it might occasionally shuffle.
An investigation into the way substances like glass age has uncovered the first physical evidence of a material-based measure of time being reversible.
In private, many physicists admit they do not believe the particles they are paid to search for exist – they do it because their colleagues are doing it
Imagine you go to a zoology conference. The first speaker talks about her 3D model of a 12-legged purple spider that lives in the Arctic. There’s no evidence it exists, she admits, but it’s a testable hypothesis, and she argues that a mission should be sent off to search the Arctic for spiders.
