quantum cosmology

A new study suggests that decoherence—the process by which quantum systems lose coherence through interaction with their environment—suppresses quantum tunneling, with implications for understanding how quantum effects operate at cosmic scales. The finding may help explain why tunneling phenomena are constrained in the early universe and how classical behavior emerges from quantum mechanics. Physics commentators are highlighting the work as a notable contribution to quantum cosmology.

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.
