"Miracles," "anti-miracles," the LHC and underpants

Holger Nielsen of the Neils Bohr Institute, whose idea that the future may prevent the LHC from ever working properly was noted on this blog last year (way ahead of the world's media noticing, by the way) has been busy writing more articles about his surprising theories. Now he uses the terms "miracle", "anti-miracle" and even "miraculocity", so naturally I am interested.

This article from October seemingly argues that letting the decision to start up the LHC (or restrict its power) according to a card drawing/random number process is still a good idea, as if it works, it will prove backwards causation. If the random draw says everything is OK to proceed, then nothing has been lost. (Look, I think that is what he is saying, but this is not so easy to follow.)

As CERN is not about to let its multi billion dollar investment be held up by bad luck in a card draw, I guess we aren't going to see this experiment happen.

However, Nielsen is not giving up. In another article out last week, he talks about the black hole information loss problem, and how one particular solution for this can be fitted in with their "imaginary action model" and provide further reason why the LHC may never operate properly because the universe just might never let it happen. (Yes, it has just got a beam going again, but I think it is many months away from building up to high energy collisions beyond those other accelerators have already achieved.)

Nielsen's article is also, incidentally, almost certainly the only physics paper to ever refer to both high energy physics and champignon growing.

Here's what the abstract says:
This model naturally begins effectively to set up boundaries - whether it be in future or past! - especially strongly whenever we reach to high energy physics regimes, such as near the black hole singularity, or in Higgs producing machines as LHC or SSC. In such cases one can say our model predicts miracles. The point is that you may say that the information loss problem, unless you solve it in other ways, call for such a violation of time causality as in our imaginary action model!
And from the paper's conclusion, tortured English and all:
For phenomenological reasons it is of course needed that under “normal” conditions the amount of backward causation - or as we also refered to cases of backward causation, miracles or anti miracles - should be seldom. This is indeed the case both by thinking of Hartle Hawking no-boundary (mainly showing up in black holes, which are phenomenologically badly known) and in our “imaginary part of action model”, in which it is though needed a somewhat speculative argumentation to argue that the cases of backward causation get so seldom as needed for agreement with dayly life experience. We think, however, that there is a good chanse that the restriction from the history of the universe having to obey the (classical) equations of motion (at least approximately) could impose so strong restrictions on the amount of backward causation or miracles or anti miracles that it would not disagree with present knowledge. In this way we want to claim that our model is viable so far.
He does not address the issue of whether or not the baguette that nearly caused a problem recently was a "miracle". I suppose it was a pretty ineffective one, which perhaps makes it self disqualifying as a miracle anyway. A bit like Jesus curing an ingrown toenail for a day.

Ever since the baguette episode, I have been thinking about what it would take (in terms of unusual objects turning up within the LHC) to count as a miracle, and not just an unusual event. I think Tim Train's missing underpants being found as a blockage in the coolant system would count. In fact, nearly any Australian non-physicist's pair of underpants appearing up in a sensitive spot in the LHC tunnel might count. But we have to be able to identify where they came from.

For this reason, I propose that all Australians who have never been to Europe should immediately start writing their name and the date of purchase in large indelible marker pen on their underpants, in the interests of science. Men, your wives and girlfriends will understand: just refer them to this blog. Women: well, I somehow doubt you will follow my underwear writing directions anyway. Speculative physics is probably more of a male interest, after all.

A pair of Bonds briefs that appear within the LHC bearing a future date would be particularly convincing.

I joke, but I shouldn't. I would quite like backwards causation to be proved. It would give me hope of receiving Lotto numbers from the future one day.
