Cosmic 'missing' matter found drifting between galaxies, hurled there by violent galactic processes

Researchers using CHIME/FRB data and DESI galaxy maps cross-correlated thousands of fast radio bursts with galaxy locations to show a substantial amount of ordinary matter lies outside galaxies in diffuse clouds, likely ejected by energetic events such as black hole jets and supernovae—brightening the picture of where the universe’s missing baryons reside and implying these galactic processes are more powerful than previously thought.

Missing Ordinary Matter Reunited: Diffuse Gas Envelopes Galaxies and Clusters

Using thousands of fast radio burst measurements, researchers mapped where ordinary (baryonic) matter resides and found widespread, diffuse gas surrounding galaxies and galaxy clusters. This diffuse gas accounts for the universe’s missing baryons, extending up to about 4 million light-years from galaxies and suggesting energetic processes like black hole jets fling baryons far beyond visible halos, which helps reconcile observations with current astrophysical models.

Astronomer Reveals Distribution of Most Normal Matter in the Universe

Most of the universe's normal matter isn't in stars or galaxies but is distributed in the cosmic web between galaxies, with recent studies using fast radio bursts confirming that about 76% of normal matter resides in intergalactic space, supporting the Big Bang theory. Dark matter, which makes up most of the universe's mass, remains largely mysterious, but scientists are actively studying it through various methods including underground detectors and telescopes.

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.

Revealing the Faces of Ancient Humans and the Universe's Hidden Matter

This week in science, the mysterious 'Dragon Man' skull has been classified, potentially as a Denisovan, and new studies are shedding light on the universe's 'missing' matter using fast radio bursts. Additionally, research suggests psilocybin can provide long-term relief from depression, and advanced AI models may produce significantly higher carbon emissions. Other highlights include volcanic eruptions in Indonesia and concerns over groundwater depletion in the Colorado River basin.
