The extremely low-energy particles they suggest make up dark matter would have a unique signature on the cosmic microwave background ... Hot, fast-moving particles dominated the cosmos after ...

Strange particles that have mass when moving one direction but no mass when moving in another were first theorised more than a decade ago. Now, these mass-shifting particles have been glimpsed in ...

Unlike the Minkowski vacuum, which is empty, the CPT-symmetric vacuum contains a finite density of particles ... Cosmic ...

Our bodies are always moving, even when we don’t realize it ... temperature measures the average kinetic energy of the molecules or particles in an object or substance. The hotter they get ...

If you know how fast it’s moving, you can’t know where it is. Measurements that happened in the past can seemingly be erased later. Particles are sometimes waves and can be in two places at once.

"Numerical simulations of such rotating particles moving in a viscous fluid showed ... give rise to a 3D chiral active phase with a chaotic background flow," said Irvine. "Each of these was ...

Dartmouth researchers propose a novel theory suggesting dark matter originated from high-energy, massless particles in the ... related to the Cosmic Microwave Background, potentially ...
