Fluctuation Definition and 53 Threads

I have a question. I decided not to put it in the "theory" section because I'm no physicist and I don't know if I'm right. From what I understand about the fluctuation theorem, the smaller the area in which it takes place, the more likely entropy is to decrease. Could it be at the beginning...

[SOLVED] vacuum fluctuation I have a few questions about this topic. 1. If their is build energy in vacuum (from Heisenberg's uncertainty principle), for example: build: 10 J ==> here for: d(t)=h/(4pi)/10J There must be built a particle and an anti particle ==> particle has 5 J and...

In quantum physics, a quantum fluctuation is the temporary change in the amount of energy in a point in space, arising from Werner Heisenberg's uncertainty principle." Quote from wikipidia". can someone tell me what caused the first, "temporary change", i am guessing that the first temporary...
