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.

A photography of a tactile model of the Cosmic Web, that is, the large scale structure of the Universe. It features a materialization of the Cosmic Web filaments, by means of a grey mesh, and a materialization of Cosmic Web knots, by means of filled, colored blobs. Such knots include: the Great Attractor, Perseus-Pisces, Shapley, Hercules, Norma. The location of our Home galaxy the Milky Way is at the center of the model.
Check this out: this a tactile model of the Cosmic Web, produced by Amelia Ortiz Gil and @vicentjm.bsky.social as part of their project: Tactile 3D models for research and outreach in astronomy.
The model used is the Cosmic V-Web inferred from Cosmicflows-2:

Exciting new research from @akhostov.bsky.social and the COSMOS team has been posted on arXiv today (arxiv.org/abs/2503.00120)! At the Oskar Klein Centre, we are eager to explore how these data can contribute to our own work on galaxy modeling (e.g., arxiv.org/abs/2406.19437).
#Astrophysics
💥 3,628 stellar explosions reshaping our view of the Universe. Novel ZTF data (20+ publications) reveals clues on cosmic expansion & Type Ia supernovae.
This analysis by the OKC @stockholm-uni.bsky.social refines our understanding of dark energy.
