I get what you mean, but I would hardly classify failing to destroy ourselves as "good empirical evidence." For each time you replicate the experiment (and we survive) it does seem more likely that something is preventing us from turning on the LHC. But how many replications is significant (who the hell knows).
And how do you reach the conclusion that we are destroying ourselves in other universes (no evidence of this)?
After all these experiments, all you know is that the LHC isn't turning on. You don't really have evidence of anything going in potential parallel universes.
The whole argument smacks of circular logic. You're starting with the assumption that multiple universes exist (which may be a good assumption, I'm not trying to say otherwise) and use the experiments to prove something funky is happening elsewhere in the multiverse.
Such a story might be internally consistent, but I fail to see the empiricism.
After all these experiments, all you know is that the LHC isn't turning on. You don't really have evidence of anything going in potential parallel universes.
Sure you do - the probability of you making the observation that the LHC persistently fails to turn on is something like 1 if MWI is true and if a functional LHC would destroy the world; it's surely much lower otherwise.

My first reaction to this was that it had to be a joke, but I thought Less Wrong readers would like to know that The Times of London is reporting that repairs on the Large Hadron Collider have been delayed by overheating caused by a piece of bread, possibly dropped by a bird:
I'm rather confident that this is just a meaningless coincidence, but in light of the anthropic speculations last year about the LHC's technical difficulties, I thought this was worth sharing.
