comment What is the difference between a measurement and any other interaction in quantum mechanics?
Penrose suggests (controversially) that decoherence could happen when gravity becomes a relevant force. It could be verified by experiment but such experiments are at the limit of what we can currently do.

comment Speed of neutrinos
It's like asking: what is the speed of footballs? Depends on the kicker and the particular kick. Very close to c because neutrinos are super light, but not a fixed value.

comment Will Determinism be ever possible?
Those experiments show that some features of QM are actually fact. They do not determine that the QM description of reality is actually correct - there are a bunch of things that don't make much sense in QM, but are accepted since the theory works so well.

comment Speed of neutrinos
Since neutrino have mass they could theoretically have almost any speed below c, but not c. The speed would depend on the source.

comment Is (rest) mass quantized?
I understand the relation between bound states and quantization (i.e. discrete vs. continuous spectra). However, the concept of "quanta" of energy applies in both cases, since you have photons anyways, and as such - should we entertain the concept of corresponding "quanta" of mass?

comment Is Newton's Law of Gravity consistent with General Relativity?
The geodesic motion are the orbits. The Schwartzschild solution represents the gravitational field in free space where all the mass is concentrated in a spherical region.

comment Is (rest) mass quantized?
Shouldn't mass be as quantized as energy? I believe E = mc^2 holds even in QT!?
