vakuumförfall
Vakuumförfall, also known as vacuum decay or vacuum metastability, is a hypothetical cosmological event that could occur if the vacuum of our universe is not in its lowest possible energy state. Quantum field theory suggests that the vacuum, the seemingly empty space, actually has a non-zero energy density. It's possible this energy state is a "false vacuum" – a metastable state that appears stable but could, under certain conditions, transition to a lower, true vacuum state.
If such a transition were to happen, it would begin with the spontaneous formation of a bubble
The process would be catastrophic for any existing life or complex structures. Since the bubble expands at
