quantum cosmology

A new physics study reports that decoherence — the process by which quantum systems lose coherence through interaction with their environment — suppresses quantum tunneling in a cosmological context. The finding suggests tunneling effects may be far weaker in the early universe than idealized quantum models predict, with potential implications for theories of cosmic inflation and phase transitions in the early cosmos.

Penn State is hosting a workshop focused on the quantum universe, bringing together researchers to discuss quantum physics and its role in understanding the cosmos. The event covers topics at the intersection of quantum mechanics and cosmology, drawing attention from the physics community interested in how quantum effects shaped the early universe.
