Science Advisor Born2bwire mentioned: "Since the vacuum state has infinite energy, it has infinite photons. Everytime we add energy into the electromagnetic fields, we just pull a photon out of the vacuum state." How many believe this and is there a refutation to this idea... because it seems that if it is true, then beneath the quantum vacuum lies a source of infinite energy.. literally".

There's experiments that provide evidence for pairantipair annihilation within the vaccum of space, but it's too inefficient of a source to extract energy from. I think if there is "infinite" energy and we can just take whatever we want from it, there's going to need to be some more proof and equations other than just "well its probable isn't it?".
Also, virtual particles aren't real, but they aren't fake. They occupy a sort of "i" realm.

How many have read the above book "The Quantum Vacuum: An Introduction to Quantum Electrodynamics" by Peter Milonni. Is it so unique compared to others and worth the $123? (I already own dozens of QED books in ebook form). Note the book cover is entirely black without any title so it's like a collector's item. Or maybe the dusk jacket was simply removed? Descriptions: "In modern physics, the classical vacuum of tranquil nothingness has been replaced by a quantum vacuum with fluctuations of measurable consequence. In The Quantum Vacuum, Peter Milonni describes the concept of the vacuum in quantum physics with an emphasis on quantum electrodynamics. He elucidates in depth and detail the role of the vacuum electromagnetic field in spontaneous emission, the Lamb shift, van der Waals, and Casimir forces, and a variety of other phenomena, some of which are of technological as well as purely scientific importance."

If you assume the empty vacuum of deep space is the ground state of the universe, then whatever energy it may contain is inaccesible because no lower energy state is available. We also know that naive calculations of vacuum energy yield a value that is 120 orders of magnitude too high [compared to observation].
