Nearly half of the universe’s ordinary matter was uncharted, until now
SMRTR summary
Astronomers have mapped the universe's "missing" ordinary matter using fast radio bursts and X-ray observations. They found 76% exists between galaxies, 15% in galaxy halos, and the rest within galaxies. A newly discovered 23 million light-year gas filament offers additional insights. These findings align with theoretical predictions and advance our understanding of galaxy formation and cosmic structure.
