According to Sabine http://backreaction.blogspot.com/2016/03/dear-dr-b-what-is-difference-between.html you can make superposition go away by just changing the basis state.. "All this is just to say that whether a particle is or isn’t in a superposition is ambiguous. You can always make its superposition go away by just wanting it to go away and changing the notation. Or, slightly more technical, you can always remove a superposition of basis states just by defining the superposition as a new basis state. It is for this reason somewhat unfortunate that superpositions – the cat being both dead and alive – often serve as examples for quantum-ness. You could equally well say the cat is in one state of dead-and-aliveness, not in a superposition of two states one of which is dead and one alive." How do you reconcile this with Penrose collapse by gravity? If penrose superposition is real that is collapsed by gravity.. how does it deal with making superposition go away by changing basis?
