In quantum field theory, a false vacuum is a metastable sector of space that appears to be a perturbative vacuum, but is unstable due to instanton effects that may tunnel to a lower energy state. This tunneling can be caused by quantum fluctuations or the creation of high-energy particles. Simply put, the false vacuum is a local minimum, but not the lowest energy state, even though it may remain stable for some time. This is analogous to metastability for first-order phase transitions.

Famous quotes containing the words false and/or vacuum:
“Sir Andrew Aguecheek. I know, to be up late is to be up late.
Sir Toby Belch. A false conclusion. I hate it as an unfilled can. To be up after midnight and to go to bed then, is early; so that to go to bed after midnight is to go to bed betimes.”
—William Shakespeare (1564–1616)
“If it were possible to have a life absolutely free from every feeling of sin, what a terrifying vacuum it would be!”
—Cesare Pavese (1908–1950)
