Physicists Say They’ve Created a Device That Generates ‘Negative Mass’
Physicists have created what they say is the first device that’s capable of generating particles that behave as if they have negative mass.
The device generates a strange particle that’s half-light/half-matter, and as if that isn’t cool enough, it could also be the foundation for a new kind of laser that could operate on far less energy than current technologies.
This builds on recent theoretical work on the behaviour of something called a polariton, which appears to behave as if it has negative mass – a mind-blowing property that sees objects move towards the force pushing it, instead of being pushed away.
Now physicists from the University of Rochester have created a device that allows them to actually create these polaritons at room temperature.
