What’s interesting to me from the abstract is the fact that they experimentally construct an ordered parameter, derive an effective Schroedinger equation that uses this parameter as if it were time, and then show that this equation actually does properly describe the experimentally observed evolution of the system.
Builds a cage. Shakes it, things inside rattle. Leaves it be, things inside do not rattle.
What am I missing? ELI5
So here is the actual article and not the pop-sci woo: https://journals.aps.org/prresearch/abstract/10.1103/1h9j-df4k

That is an issue if someone figures out how to do actual vacuum decay! Rather than simulate it in ultracold gasses.
