While it’s pretty high-concept physics, the team says the discovery could eventually open up a range of applications for ZrSiS similar to that of graphene. “It is a layered material, which means once ...

An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

Physicists have taken one small-but-consequential step toward measuring the mass of an elusive "ghost particle" called a neutrino — an achievement that could poke a significant hole in the Standard ...

A new theory proposes that the universe’s fundamental forces and particle properties may arise from the geometry of hidden extra dimensions. These dimensions could twist and evolve over time, forming ...

The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental physics. The very structure of spacetime might underlie every interaction in ...

Mass is mass is mass. Physicists have three different definitions of mass, all thought to be equivalent. Measurements of the distance between Earth and the moon confirm that two of those masses are ...

Explore a physics simulation of a mass on a frictionless table connected to a hanging mass! Learn about tension, acceleration, and Newton’s laws with this clear, visual demonstration—perfect for ...

Jump start physics problem with a mass on a spring. This video explains the setup, key assumptions, and the step-by-step physics needed to solve for motion, energy, and forces in a spring–mass system.
