    <dc:creator>sunpig</dc:creator><description><![CDATA["How do we apply the precautionary principle to exotic, low-probability risks?

"[...] the CUORE experiment is actually going outside of the envelope of what we think is going on in the universe. In the past, the universe has been hotter, so there would not have been any large masses at 6 milliKelvins. And with a 3 Kelvin background temperature, there would not be any natural objects this cold. (Since 1995 there have been small Bose-Einstein condensates in the hundred nanoKelvin range on Earth, but the argument is the same.)

"How risky is it to generate such an outside of the envelope phenomenon? There is no evidence from the past. There is no cause for alarm given the known laws of physics. Yet this lack of evidence does not argue against risk either. Maybe there is an ice-9 like phase transition of matter below a certain temperature. Maybe it implodes into a black hole because of some macroscale quantum(gravity) effect. Maybe the alien spacegods get angry. There is an endless number of possible hypotheses that cannot be ruled out."]]></description>
