Changes

::::It is not wrong to suggest that the speed of light is different than the currently accepted value (but this would actually change the definition of the meter, while the value for the speed of light would stay the same), I'm just saying that it's a bit silly for someone to conclude that the speed of light is changing based on the fact that the measurements of the speed of light have changed over the centuries.  It shows a lack of understanding of the methods used to conduct those measurements.  Measuring the speed of light requires either modern knowledge of electromagnetism or mirrors rotating very fast that are very far apart and extremely precise knowledge of how fast those mirrors are spinning and how far apart they are.  It also requires measuring the displacement of a beam of light which can be unimaginably difficult using anything but a laser and large-radius spherical mirrors (neither of which existed hundreds of years ago).  --[[User:MichaelK|MichaelK]] 14:06, 10 May 2008 (EDT)
