What the Copenhagen interpretation says — the wavefunction collapse is fundamental, observation creates reality

What decoherence explains — the appearance of wavefunction collapse through interaction with the environment

Decoherence explains wavefunction collapse due to environmental interactions

What the measurement problem asks — why does a quantum superposition collapse to a definite state upon observation

Quantum measurement problem: Superposition collapses due to observer interaction

What the renormalization group does — explains how physics changes with the scale of observation

Renormalization group describes scale-dependent behavior in physical systems

What the Many-Worlds interpretation claims — all outcomes occur in branching parallel universes, no collapse

Many-Worlds posits simultaneous existence of all possible outcomes in separate, non-interacting universes

What the Aspect experiments confirmed — Bell inequality violations prove quantum nonlocality is real

Aspect experiments demonstrated quantum entanglement's nonlocality, violating Bell's inequalities

What Anderson localization is — disorder can cause waves to become trapped in a random medium

Anderson localization: Disorder traps waves in a medium due to interference
