Signals inside CPUs don't travel as fast as they do in fiber optics. Even there, the speed of light inside an optical bundle is less than in free space. This is one of the reasons for shortening the paths signals must travel inside a CPU.<BR /> Fri, 18 Apr 2008 15:50:57 GMT TimP 2008-04-18T15:50:57Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/CPU-s-faster-than-light/m-p/902079#M4280 Not sure where to put this, just want an engineer's perspective on <A href="http://digg.com/hardware/CPU_s_Faster_Than_The_Speed_of_Light">this</A>:) Fri, 18 Apr 2008 06:28:48 GMT https://community.intel.com/t5/Intel-Moderncode-for-Parallel/CPU-s-faster-than-light/m-p/902079#M4280 cratzy 2008-04-18T06:28:48Z https://community.intel.com/t5/Intel-Moderncode-for-Parallel/CPU-s-faster-than-light/m-p/902080#M4281 No, the laws of physics haven't been repealed.
