Quantum Foundations
Does an observer-independent reality exist?
UNKNOWNimportance 74/100 · Unknown
Whether physical properties have definite values independent of measurement.
Current explanations
Realist interpretations affirm an observer-independent world; some readings of quantum theory (e.g. QBism, relational QM) make outcomes observer-relative.
Research progress
Bell and related no-go theorems constrain which realist pictures are viable, ruling out local hidden variables, but do not eliminate realism as such.
