In our everyday experience, if you push something, it moves away from you. But objects with negative mass would turn that basic principle on its head and accelerate towards you instead.

Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn't ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

It's embarrassing, but astrophysicists are the first to admit it. Our best theoretical model can only explain 5 percent of the universe. The remaining 95 percent is famously made up almost ...

Physicists have created a mind-bending new fluid that has ‘negative mass.’ This means that, unlike other objects, the material accelerates backward when pushed, instead of in the direction of ...

Bose-Einstein condensates are used to explore a wide range of fundamental questions in physics (not the apparatus used in the latest research) Physicists have created a fluid with "negative mass ...

Why matter always seems to have positive mass is one of the unsolved mysteries of physics. We may nowadays have almost become accustomed to the concept of negative interest rates, but what would ...

Scientists have created a new superfluid that has a negative mass, meaning that if it's pushed to the right, it accelerates to the left and vice versa. The bizarre behavior may sound like a ...

Sound has negative mass, and all around you it's drifting up, up and away — albeit very slowly. A phonon — a particle-like unit of vibration that can describe sound at very small scales — has a very ...

Physicists create 'negative mass' Experimental technique can help probe phenomena in astrophysics and cosmology Date: April 17, 2017 Source: Washington State University Summary: Physicists have ...
