3/9 The solution came from fast radio bursts (FRBs)—brief, powerful flashes of radio energy that travel billions of light-years across space.
"The FRBs shine through the fog of the intergalactic medium," says lead author Liam Connor of Harvard.

Simulation of the universe's cosmic web, showing hot gas filaments where most normal matter resides. The image depicts a 2.7 billion light-year across slice, revealing the distribution of this previously unaccounted for matter. The vibrant colors represent density variations in the hot, intergalactic gas. The distribution of dark matter is likely similar, though its composition remains a mystery.

False-color X-ray image of the Fornax galaxy cluster's core, showcasing high-energy emissions from giant galaxies and a vast cloud of hot gas. The cluster's movement through intergalactic space suggests the influence of unseen dark matter structures. 65 million light-years away, spanning nearly 900,000 light-years.
