Astronomers uncover rotating cosmic filaments spanning hundreds of millions of light years

These ghostly bridges between clusters may be spinning slowly

New research finds enormous cosmic filaments in the universe’s web are slowly rotating. These faint structures stretch hundreds of millions of light-years and link galaxy clusters across vast distances. The observation challenges older ideas that matter’s large-scale evolution was mostly static, instead suggesting these colossal “bridges” are dynamic and have been changing for billions of years.
