Time-Traveling Photons - LIGHT MATTERS 09.30.2016

On this month’s show, we take a look at the possibility of time travel, as researchers at the University of Queensland have simulated it using photons and quantum particles. Also on the show, we talk about ongoing work by a company in Idaho to develop solar-paneled roads, highways, parking lots and sidewalks, with the ultimate goal of generating widespread green renewable energy. We offer a glimpse at the October issue of Photonics Spectra, which includes features and a special section dedicated entirely to the field of optics, and researchers in the U.K. have cracked a codex, employing hyperspectral imaging to reveal never-before-seen pictographic scenes from a 500-year old Mexican scroll.
