Is tunnelling from nothing a transition?

Sorry for my abysmal level of ignorance, but I'm not understanding why quantum tunneling from nothing is considered a possible starting point for a multiverse, when the permanence of our pocket universe within the multiverse is also considered to be threatened by a phase transition if its vacuum has any pairing of masses for the Higgs boson and top quark lower than those in a certain sequence of pairs. Would a pocket universe whose Higgs and top-quark pair were at any mass be threatened with a (possibly lower) risk of annihilation by quantum tunneling from nothing, or might it just blink off for an interval (perhaps imperceptibly short) if their masses were consequently left inadequate for stability?

Thread 'Quantum behaviour of an electron around a positively charged sphere'

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!

Thread 'Does a qubit break interference in the double slit experiment?'

According to recent podcast between Jacob Barandes and Sean Carroll, Barandes claims that putting a sensitive qubit near one of the slits of a double slit interference experiment is sufficient to break the interference pattern. Here are his words from the official transcript: Is that true? Caveats I see: The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might...
