Virtuals particles, vacuum and infinite energy

Hi guys I have a question for you. Virtual particles can appear anywhere and when they have enough energy they turn into real. And if it happens long enough in a vacuum, will it remain a vacuum? If not, then is matter infinite?

No, they don't

Since it doesn't happen that question makes no sense

If the universe is infinite, then matter is infinite, but not having anything to do with virtual particles

Please post reference links when making assertions like this at PF. Please make sure that the references are to credible scientific articles and not "Pop-Sci" articles. Thanks.

In the Casimir effect, a force is actually measured between the two metallic plates. This was physically interpreted based on quantum vacuum fluctuations. By removing wavelength beyond a threshold the virtual particles allowed energy is constrained between the plates. Thus the observed pressure in the Casimir effect, would come from a lower vacuum energy density between the plates than outside.

Now the question is the following: if the Casimir force is real, then it could generate some work at maximum dW=F*dl (l is the distance between plates). So, can you elaborate on the fact that vacuum energy cannot be real.
