Did quantum fluctuations create matter and energy out of nothing?

I found a popular science article explaining that the existence of the Higgs particle can be interpreted to mean that matter and energy are created by quantum fluctuations of nothingness (i.e. the ...

Probability of Vacuum Fluctuations near Charges

A short, simple enough question, if you know about field theory, which unfortunately I don't. Are vacuum fluctuations more probable near a charge, for example an electron with negative charge? I ...

Would virtual particles “dissolve” objects given enough time?

Suppose for the sake of argument that you have an object in a vacuum. According to QFT, virtual particle pairs pop in and out of existence constantly. Given enough time, would it be reasonable to ...
