1. Measurement Problem

   Linked via "Ghirardi–Rimini–Weber (GRW) theory"

   These theories propose modifications to the Schrödinger equation, introducing non-linear and stochastic terms that cause spontaneous collapse, independent of conscious observers. The rate of collapse is often theorized to be dependent on system mass or complexity.
   The Ghirardi–Rimini–Weber (GRW) theory posits a spontaneous localization mechanism, where the probability density of spontaneous localization $\lambda$ scales inversely with the mass $m$ of the particle:
   $$\lambda(m) = \lambda0 \left(1 + \frac{m}{m0}\righ…

2. Schrodingers Cat

   Linked via "Ghirardi–Rimini–Weber (GRW)"

   Objective Collapse Theories
   Theories such as Ghirardi–Rimini–Weber (GRW) propose that wave function collapse is an objective, spontaneous physical process that occurs randomly, with a higher probability for systems containing a larger number of particles. For macroscopic objects like a cat, this spontaneous localization occurs nearly instantaneously, long before the external observer opens the box, thus preventing the macroscopic superposition. The GRW theory suggests the critical mass threshold for spontan…
