   Apr 13, 2017 · 4. A perfect vacuum is defined as a state with no matter particles, and also no photons. This state is impossible to achieve experimentally because it is nearly impossible to remove the matter, and is impossible to eliminate all the photons. Since there is also some energy available, virtual particles can hop into and out of existence.

   What is a perfect vacuum?

   • A perfect vacuum contains no particles and has a pressure of zero. In science, a perfect vacuum is an ideal vacuum that contains no particles and has a pressure of zero (in any pressure units). A perfect vacuum is a theoretical concept that cannot be achieved in the real world. But, it’s possible to come close, both in nature and in the lab.

   Can a vacuum form a perfect vacuum?

   • Forming a perfect vacuum is impossible because no device removes every single atom or molecules from a space, we can’t expand a volume infinitely, and we can’t prevent all outside particles from getting inside a container. Researchers achieve near-perfect vacuums using multiple vacuum pumps. But, there are other considerations, too.

   Is a perfect vacuum a real book?

   • A Perfect Vacuum: review of the book itself. This is the only real book reviewed in the entire collection. However, even this is not entirely real. For example, the reviewer criticized the preface of A Perfect Vacuum, entitled Auto- Momus, even though the actual A Perfect Vacuum does not have a preface or a section titled Auto-Momus.
