I know I am asking out of my limits, but i felt relaxed thinking about this.

Now I read somewhere about quantum fluctuations (that energy can be generated in randomly at two positions where total sum of the energy is zero.

So i researched about it a little and found that they are completely probabilistic (Heisenberg' principle)

1. Are they observable?
2. And in electrostatics in problems where cavity is involved we fill the cavity with positive and negative charge (so i thought of if i fill the cavity with the charge(positive or negative) of the rest of the body) and take away the rest of its counterpart charge very far away from the body)---------------but that would be a very probabilistic case(might be 1 in trillions).
So this made me think of the question 1

I know it might be difficult for all to explain this to a high school student but I have faith that you will find a way :)
