Proposed end of the world update

Also while I was away, Rainer Plaga made his response to the criticisms of his original paper suggesting that the Large Hadron Collider could create a dangerous, earth threatening, mini black hole.

He added an appendix to his paper on arXiv, here, saying that Giddings and Mangano's criticism that he used an equation incorrectly is just wrong. For the earlier explanation of the background, see my posts here, here and here.

I'm in no position to judge the accuracy of Rainer's rejoinder, just as I had trouble understanding Giddings and Mangano's criticism. And no physicist on the Web seems to have commented on Rainer's response.

So: who knows? Some informed comment on this would be welcome, but I guess money worries are more important that the end of the world...

UPDATE: the accident that shut the LHC down appears to require more work to fix than first thought. Nature is reporting it won't be turned on again til June 2009, but even then some seem to think that is optimistic.
