      Well see i would have said ahh the speed of light…but being a non-physicist i went and looked up here
      http://physicsworld.com/cws/article/news/2810

      actually i googled and looked for a decent article but anyway

      what this seems to say is that a laser pulse travels at the speed of light but this is the average speed with some wavelengths of light travelling faster or slower
      so the faster wavelength travels at 300x the speed of light
      or at least thats what these physicists claim
