Scientists are using revolutionary 3D galaxy maps and advanced computational techniques to uncover the hidden structures of dark matter, the invisible substance shaping the universe. Through a method called field-level inference (FLI), researchers are reconstructing the intricate web of dark matter by analyzing galaxy positions in unprecedented detail. This breakthrough offers new insights into how dark matter interacts with visible matter and complements existing techniques like gravitational lensing, pushing the boundaries of our understanding of the cosmos.
