A new study by scientists at @oskarkleincentre.bsky.social & @fysinfo.bsky.social have developed an AI-powered method to build a digital twin of the Universe—reconstructing its early state and simulating its entire evolution up to the galaxies we see today. www.okc.albanova.se/news/leverag...

OKC researchers presents an AI method to recover the Universe’s initial conditions and simulate forward—toward a digital twin of the cosmos. MNRAS (Aug 2025). Details: www.okc.albanova.se/news/leverag... #cosmology #AI #neuraloptimizer #Space

Astronomers from @oskarkleincentre.bsky.social participated in study of exploding star that lacks all of the most common elements in universe. This rare stripped star helps understanding how & where elements like sulphur & silicon form. New study in @nature.com.web.brid.gy www.su.se/english/news...
