Summary

Story summary

Astronomers find that most of the Universe's ordinary matter, or baryons, is missing from galaxies and hidden in the intergalactic medium, with fast radio bursts helping map its distribution.
Normal matter distribution is crucial for understanding cosmic structures, including black holes.
The James Webb Space Telescope (JWST) sees red glimmers that may signal massive cosmic structures rather than points.
These findings challenge cosmological models and open new avenues for exploration.
