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.
