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:
“What makes all doctrines plain and clear?
About two hundred pounds a year.
And that which was proved true before
Prove false again? Two hundred more.”
—Samuel Butler (1612–1680)
“Teenagers who are never required to vacuum are living in one.”
—Fred G. Gosman (20th century)
