The antenna is in Upper Michigan, and is used to communicate with submarines throughout the world, at very low bit rates. But the speed of ULF waves through the earth is certainly not c, so this would be no test of fundamental physics (I don't know what the effective index of refraction for rock is in this band). There would also be HUGE ambiguities in the timing of ULF waves that would make such a measurement unable to make a significant measurement of signal speed. Tom Roberts |

Tom Roberts- Hide quoted text - - Show quoted text - What is the path of these waves? What first came to my mind was http://en.wikipedia.org/wiki/Terrest...ationary_waves It looks like those waves travel around the curve of the surface, not the straight line through the earth. |
