The molecular hydrogen ion H₂⁺ is the simplest molecule. This simplicity makes it a perfect study object for physicists, as ...

A new estimate of the ghostly particle’s maximum possible mass brings physicists a tad closer to understanding the universe. By Katrina Miller Katrina Miller studied neutrinos in graduate school, but ...

One of the most basic assumptions of fundamental physics is that the different properties of mass -- weight, inertia and gravitation -- always remain the same in relation to each other. Although all ...

Negative mass was something physicists never thought they would find – let alone create. For more than a century, physics has operated on the foundation that mass is always positive. From Newton’s ...

All the tech we rely on, from cars to smartphones, was engineered using physics. You don’t need to know the science to use these things. But a well-rounded human should understand at least some of the ...
