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

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

Copenhagen interpretation: Observing a system collapses its wavefunction, shaping reality

What the Olbers' paradox asks — why is the night sky dark if there are infinite stars (answer: finite age of universe)

Olbers' paradox: Night sky dark due to universe's finite age limiting starlight

What the CMB power spectrum tells us — the age, composition, and geometry of the universe

CMB power spectrum reveals universe's age, composition, and large-scale structure

What Bell's theorem proved — no local hidden variable theory can reproduce all predictions of quantum mechanics

Bell's theorem disproved local hidden variable theories' ability to match quantum mechanics' predictions

What universality means in phase transitions — different systems show identical critical exponents

Universality in phase transitions: identical critical exponents across diverse systems

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

Decoherence explains wavefunction collapse due to environmental interactions
