These Particles Only Move in One Direction. Scientists Think They Could Revolutionize Computing. Story by Caroline Delbert • 2d ...

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 ...

The scientists compared the behavior of the particles within the material to a train traveling on a network of tracks. In some directions, this train can move extremely fast, as if it had no weight.
