Re: 100/100?
Light traveling in a fiber optic cable generally travels at about 2/3's the speed of light. Electricity, depending on the specific medium, can approach the speed of light in a metallic cable. So fiber optics are actually "slower" than copper transmisions. |

Golden, CO | Wouldn't single mode fiber (with a very narrow core) make light travel closer to c in said fiber? |

Actually light does travel at the speed of light in a fiber, the speed difference comes from the refraction of the protons off of the internal walls of the fiber which happens enough that it essentially increases the actual time it takes for the proton's to get from point A to point B which creates the illusion that light is traveling slower...essentially, the protons in a fiber don't take a direct route.
Electrons travel on the surface of copper at the speed of light and therefore are able to take the proverbial "as the crow flies" route so they get from point A to point B essentially at the speed of light.
Regardless, Smithvilles PR is written poorly. |

The transceiver for proton internet would be pretty big and expensive, possibly ionizing and require extensive saftey precautions to be OSHA complaint. |
