Baryons Take the Lead in Galaxy Clusters, MOND Gains Ground

A Bonn-led study analyzing 46 nearby galaxy clusters finds their mass is about twice as heavy in baryonic matter as previously thought, due to components like stellar remnants and intracluster light. The revised accounting brings cluster masses closer to MOND predictions and challenges the need for exotic dark matter, with authors suggesting a reevaluation of dark-matter-focused research funding.

Scientists Use Unique Energy Pulses to Map the Universe

Scientists are using fast radio bursts (FRBs) to locate the universe's missing baryonic matter, which is difficult to detect with traditional methods. Recent discoveries suggest that FRBs can serve as cosmic probes to map the distribution of ordinary matter, helping to solve the longstanding 'missing baryon problem' and improve understanding of cosmic evolution.
