On the big screen, in video games and in our imaginations, lightsabers flare and catch when they clash together. That clashing, or interference, happens only in fiction — and in places with enormous magnetic and electric fields, which happens in nature only near massive objects such as neutron stars. A team of physicists has discovered discovered that it is possible to produce this effect in a laboratory setting, using a class of novel materials.
