For the first time: the experiment of the two cracks in the timeline

  • No comments
In an article published in the magazine Nature Physics, a team of researchers from Britain, the USA, Germany and Australia demonstrated for the first time the two cracks experiment in the timeline. Instead of a spatial dispersion on a screen, the temporal crack created a dispersion in the light spectrum,
