  Query Language Understood by SQLite: VACUUM
If VACUUM is invoked with the name of a table or index then it is suppose to clean up the named table or index.
The VACUUM command is a no-op for in-memory databases.
As of SQLite version 3.1, an alternative to using the VACUUM command is auto-vacuum mode, enabled using the auto_vacuum pragma.

 Vacuum energy - Science Articles
Quantum field theory considers the vacuum ground state not to be completely empty, but to consist of a seething mass of virtual particles and fields.
Some believe that vacuum energy might be the "dark energy" (also called quintessence) associated with the cosmological constant in General relativity, thought to be similar to a negative force of gravity.
During the 1980s, there were many attempts to relate the fields that generate the vacuum energy to specific fields that were predicted by the Grand unification theory, and to use observations of the Universe to confirm that theory.

 Explosive Decompression and Vacuum Exposure
Its focus is on decompression, rather than vacuum exposure per se, but it still has a lot of good information, including the results of decompression events involving humans.
This event is generally known as "explosive decompression," and apart from the simple effect of vacuum on the body, the explosive decompression event itself will be hazardous.
For more technical details, a paper discussing the medical effects of sudden vacuum exposure on a human, and discussing the emergency medical response to a decompression emergency, can be found in Dr. Tam Czarnik's paper Ebullism at 1 Million Feet.

 vacuum
So, when you ask about the energy density of the vacuum, you get different answers depending on whether the person answering you is basing their answer on general relativity or quantum field theory.
Naively we can try calculating the energy density of the vacuum by simply summing up the zero-point energies of all the vibrational modes of the quantum fields we are considering (e.g.
For a calculation that explains why the vacuum having positive energy density means it has enough negative pressure to make the expansion of the universe accelerate, see the cosmological constant section of my website about the meaning of Einstein's equation.

So, when my wife and I went shopping for a vacuum cleaner, we zeroed in on models that were capable of vacuuming the acres of wall-to-wall carpeting in our home and sweeping the tile and vinyl that make up the rest of our floors.
A HEPA filter and disposable dust bags were necessities because of her allergies (your allergist will tell you that bagless cleaners are an exercise in futility unless you take the cleaner completely out of the house and shut the door behind you when emptying the dirt container).
After vacuuming the carpet in the master bedroom and some of the living room, we already noticed a measurable level of dirt in the first bag, an indication of the dirt left behind by our aging Hoover Decade 80 upright.
