Something From Nothing – Physicists Mimic the “Impossible” Schwinger Effect

Superfluid helium reveals a manageable analog to the Schwinger effect. It deepens understanding of vortices and quantum tunneling. In 1951, physicist Julian Schwinger proposed that applying a constant electric field to a vacuum could cause electron-positron pairs to emerge spontaneously, a process known as quantum tunneling. Why can’t this matter from nothing idea power Star [...]
