what is vaccum decay​

Answer 1

Of all the ways the Universe might die, vacuum decay is the most efficient. ... The Higgs potential determines whether the Universe is in one of two states: a true vacuum, or a false vacuum. A true vacuum is the stable, lowest-energy state, like sitting still on a valley floor.
