Time span within which conservation can be violated

When you say conservation of energy can appear to be violated, but only for small times. Can't a minute be stretched or shortened? How long can you really say a fluctuation takes place? —Preceding unsigned comment added by 24.109.219.47 (talk • contribs)

The time span within which conservation can be violated cannot be longer than what's permitted by the uncertainty principle. It's an immensely small period of time; minute fractions of a second. A minute? Nowhere near. PsiCop 00:15, 15 June 2006 (UTC)[reply]

How much energy is required to separate a quantum fluctuation

How much energy is required to separate a quantum fluctuation so the virtual pairs do not annihilate? I am aware that around the event horizon of a blackhole this is theoretically observed. One part of the virtual pair falls into the blackhole and the other part moves away from the blackhole into the observable universe. This creates the appearance of radiation coming out of blackholes, known as Hawking Radiation. Is there a way to measure the minimum amount of energy needed to separate the virtual pairs of a quantum fluctuation? —Preceding unsigned comment added by Skysunny7th (talk • contribs)

This article is very poor

THe section under the title "Quantum Fluctuations of a field" does not speak about quantumn fluctuations per se, but about what seems a rather arbitrary choice of subject related to this topic, which would be the distinction with thermal fluctuations. Also, in general, the probability to observe a certain state in quantum mechanics depends on the "linear combination" that adds up to form that state; this would be what the second part of the article is about (?). Shouldn´t the article be about only the first part? At least, there should be more evidence in support for the need to speak about "quantum fluctuations".--190.188.0.22 (talk) 14:30, 17 May 2010 (UTC)[reply]
