The complete circuit for measuring the number of particles created in an expanding universe. Credit: Scientific Reports (2025). DOI: 10.1038/s41598-025-87015-6. A new study published in Scientific ...
“In cosmology there’s this quantum effect,” Ralf Schützhold tells PhysOrg.com. “In the universe, there is a ground state, where it is empty. But if the universe starts to expand or contract, the ...
Matter creation dynamics in cosmology examines mechanisms by which the expanding Universe may generate particles through purely gravitational or geometric interactions. In this framework, the cosmic ...
Scientists have used quantum computers to simulate how particles can appear in an expanding universe. This study, published in Scientific Reports, helps us better understand some of the mysteries of ...
