Speed of Light Inconstant?
DHR writes "Australian scientists have discovered that light isn't quite as fast as it used to be." We've done previous stories on these findings. Those of you with subscriptions to Nature can read the actual paper, the rest of us will just have to suffer.
It's that same group saying the same thing again. Although I haven't reviewed their latest paper, I remember that I wasn't impressed with the statistical analysis of their data, as of the previous paper.
Personally, I won't find the evidence convincing untill another group takes some their own data and gets similar results. Given that many astronomers have similar sentiments, it seems that giving VLT time to the same group seems not the best use of VLT time.
Of course, if no other astronomers find the likelyhood of the discovery worth the effort of making the observations, then it may be difficult to get independant confirmation. Given that it would be a really big deal if true, I think that says a lot about how seriously the astronomical community takes these claims.
