Is false vacuum theory real
WebThe false vacuum theory is a controversial idea that suggests that our universe is actually just a small part of a much larger, ever-expanding multiverse. Some scientists believe … In quantum field theory, a false vacuum is a hypothetical vacuum that is relatively stable, but not in the most stable state possible. This condition is known as metastable. It may last for a very long time in that state, but could eventually decay to the more stable state, an event known as false vacuum decay. … See more A vacuum is defined as a space with as little energy in it as possible. Despite the name, the vacuum still has quantum fields. A true vacuum is stable because it is at a global minimum of energy, and is commonly assumed … See more When the false vacuum decays, the lower-energy true vacuum forms through a process known as bubble nucleation. In this process, … See more Bubble wall, propagating outward at nearly the speed of light, has a finite thickness, depending on ratio between energy barrier and energy gain obtained by creating true vacuum. In the case … See more • Eternal inflation – Hypothetical inflationary universe model • Supercooling – Lowering the temperature of a liquid below its freezing point … See more Existential threat If our universe is in a false vacuum state rather than a true vacuum state, then the decay from the less stable false vacuum to the more stable … See more Electroweak vacuum decay The stability criteria for the electroweak interaction was first formulated in 1979 as a function of the masses of the theoretical Higgs boson and the heaviest fermion.

Vacuum decay is the ultimate ecological catastrophe; in the new vacuum there are new constants of nature; after vacuum decay, not only is life as we know it impossible, so is chemistry as we know it.
Webthe energy conditions more appealing: the “vacuum” in modern field theory turned out to be anything but a simple “empty” state, and in particular a vacuum state violated the energy conditions. Several Soviet cosmologists, who apparently abhorred the sin-gularity more than the vacuum, proposed that an early vacuum-like state would lead WebOne caveat is that if the Universe is a false vacuum that locally decays into a Minkowski or a Big Crunch -bound anti-de Sitter space in less than 20 billion years, then infinite Boltzmann nucleation is avoided.
