Astronomers have presented the most detailed view of the universe’s history, suggesting it may have originated from an “instanton” rather than a singularity. This revelation, visualized through two innovative plots, also delves into the mysteries of the universe’s boundaries.Lead author Honorary Associate Professor Charley Lineweaver from ANU said he set out wanting to understand where all the objects in the universe came from.
