Résumé |
In the early universe, quantum vacuum fluctuations are amplified and stretched to large distances, giving
rise to cosmological over-densities that seed the large-scale structure of our universe. However,
astronomers usually analyze the data with purely classical techniques and apparently never need to rely on
a quantum formalism to understand them. So are there observational signatures of the quantum origins of
primordial perturbations? If confirmed, would that challenge foundational aspects of quantum mechanics? |
