Does Cold-Induced Melting Challenge the Many Worlds Interpretation?

[debert]

According to this link:

http://www.stumbleupon.com/su/7ZF6uJ/io9.com/5757404/awesome-discovery-of-the-week-glass-melts-when-it-gets-too-cold

... Glass, it turns out, is the exception. Once it gets close to absolute zero, it melts again. ...​

My question:

“Now, according to what I am trying to understand about this, wouldn’t this set up a strange conundrum for the many worlds view? If the wave functions comprising the glass have already manifested themselves as particles in our universe, how could they return to potential wave functions due only to temperature?”

As I recently explained in https://www.physicsforums.com/showpost.php?p=3149720&postcount=6" post a few days ago, when the location of an particle has been 'measured' (i.e. it's been detected 'as a particle'), it doesn't stay that way. In particular at low temperatures.

Hello alxm,

But it doesn't appear that the glass would have been left in an unobserved or unmeasured state, does it?
