Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

Matter with negative mass, a seeming impossibility, could actually have existed in the early universe, a new study shows. A novel solution to Einstein’s equations for gravity permits the existence of ...

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. It sounds like ...

Scientists have struggled for decades to identify the constituent particles of dark matter, but they’ve had little to show for all their efforts. A new study at Case Western Reserve University is now ...

Physicists have designed the first device to create particles with charged negative mass. The breakthrough could lead to an entirely new way to generate laser light using only a tiny amount of energy.
