Do neutrinos experience tunneling, and thus we think they have no mass yet they do because they are tunneling?

Not really.

Neutrinos are a highly relativistic particle, so the proper treatment involves QFT. Tunneling in QFT is rather subtle and not very apparent, and only really emerges in more of a quantum mechanics setting.

The way they acquire mass is not understood well, and there are many proposals for exactly how they might gain (the very small) mass.

My personal opinion, follows more along the lines of an SO(10) GUT theory seesaw mechanism.

Could you say something about neutrino oscillation?

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!
