Agree with RB
QuoteQuote from RobertBryant The actual article is about NUCLEATION.. not nuclear transmutation
Axil salad is confused and confusing.
On the contrary, the article is about the discovery of False Vacuum Decay in a Bose Einstein Condensate and a domain wall that protects the False Vacuum Decay decay mechanism.
False Vacuum Decay is a process that changes the laws of nature actioned by the nature of the ambient vacuum..
In quantum field theory, false vacuum decay is now an experimentally verified event where a vacuum that is relatively stable decays into a alternative state. This happens through the creation of small bubbles. Nucleation is the mechanism that forms the domain wall that creates the EVO bubble. The formation of a domain wall proves that the EVO contains a vacuum state that differs from that of the ambient vacuum.
We now understand that these small bubbles are EVOs forms through the creation of a domain wall the keeps the EVO vacuum state from mixing with the ambient vacuum state.
The ambient false vacuum is a vacuum that is metastable, meaning it is relatively stable but not in the most stable state. A false vacuum can last for a very long time, but it could eventually decay into a more stable state.
.
The idea of false vacuum decay is that the true lowest energy is lower than what we think. A false vacuum is at a local minimum of the energy function, while a true vacuum is at a global minimum.
Learn about the false vacuum
I have posted elsewhere the reasons why the EVO is a bubble of anti De-Sutter Spacetime.
The WIKI states as follows:
The present false vacuum state is called (de Sitter space), while tentative true vacuum is called, (Anti-de Sitter space).[22][23]
