280 Galaxies Spin Together in Cosmic Filament, Defying Models

• Astronomers discovered a cosmic filament containing 280 galaxies, spanning 50 million light-years, that appears to rotate as a whole.
• Many galaxies within this filament exhibit aligned spins, matching the filament's overall rotation, challenging previous assumptions about random galactic alignments.
• The filament is described as young and 'dynamically cold,' with gas-filled galaxies, offering insights into early star formation and galaxy growth.
• Researchers used data from the MeerKAT radio telescope and optical surveys to study this unique structure, which acts like a "fossil of old cosmic streams."
• The discovery raises new questions about how large cosmic structures influence galactic rotation and how the universe builds its vast web.

Why It Matters: This rotating cosmic filament challenges galaxy formation theories and universe structure.
