And I've asked repeatedly for people to quantify how much they think planet Earth is worth. And again, not one person has bothered.
You fail to specify valuation terms, but we all know where you're going and that point is moot anyway.

You're basing your argument on the fact that the catastrophic event probability is non-zero. The burrito statement was to point out that everything's catastrophic event probability is non-zero. All the data and studies to this point show these tests to be safe--in other words, their no more dangerous (from a earth-ending event standpoint) than sneezing is.

You want to know what probability is low enough for us to consider it to be zero. I'll bite on this one. To me, that is when the probability is no greater than the inherant probability in quantum theory. The burrito in the microwave, if you will. And since the study and subsequent follow up study, as well as all recorded observations and calculations to this date conclude that the LHC experiments do not pose a threat, I consider this event to be no different than any other event.

Now, if you want to claim that the LHC will pose more than a burrito risk, then it is up to you to demonstrate that probability.
