Virtual particles

[sirios]

Hello everyone, I am here today with a doubt, I first apologize for my ignorance on the subject, but come on, the uncertainty principle predicts that in the "vacuum" there are virtual particle that cancels out constantly, but my question is: which is the amount of energy that exists in this vacuum in 1 cm ^ 2? the second question, and simpler: why does it happen? or quantum mechanics can not explain, again sorry for my ignorance.

No it does not. Virtual particles do not exist. See phind's links for details.

which is the amount of energy that exists in this vacuum in 1 cm ^ 2?

1 cm³? Quantum mechanics doesn't make a prediction for that, it doesn't matter in quantum mechanics either (because absolute energy values are meaningless, only differences are important). This changes if you want to include gravity, but we don't have a full quantum theory of gravity.
