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.
