The classic physics problem example of symmetry breaking is a pencil sitting directly on its tip (pointed down), but it's possible for the pencil to balance on its tip if we reduce the thermal(adsbygoogle = window.adsbygoogle || []).push({});

fluctuations to zero by cooling it to close zero degree.

Quantum fluctuations require/mean that after some time no matter that it was ‘perfectly’ balanced it is going to fall over. So the question is that would the pencil, a classical object, fall over due to quantum fluctuations in a thought experiment pioneered by Einstein?
