One of your sources in this article claims, “After all, even the sacred first law’s conservation of energy breaks down in the quantum realm, albeit in a limited way, he notes. That’s because Heisenberg’s uncertainty principle allows energy momentarily to appear from nothing, although it must be quickly paid back.” This claim is heard occasionally, but I am wondering what the justification for it is, and where it can be found. Many authors emphatically deny that quantum mechanics borrows energy from nothing. Thus, is there a derivation from quantum field theory, or is it time to put to rest a myth?
