An Oxford-led team identifies a giant, razor-thin cosmic filament about 140 million light-years away that is rotating with galaxies aligned to its spin, offering new insights into how galaxies acquire angular momentum and evolve. The finding, enabled by MeerKAT’s MIGHTEE survey and complemented by DESI and SDSS data, challenges existing models of galaxy formation within the cosmic web.
Researchers have experimentally confirmed that angular momentum is conserved when a single photon splits into a pair, validating a fundamental quantum principle and paving the way for advanced quantum states useful in computing and communication.
Researchers in Germany have successfully sent single electrons along structured chiral paths, achieving chirality in electron matter waves without angular momentum. This work, which parallels earlier research with photons, could have significant applications in electron microscopy and the study of magnetic materials. However, some scientists are skeptical about the claim of chirality without angular momentum and the lack of citation of previous related work.
