SUMMARY
The discussion centers on the warm-hot intergalactic medium (WHIM) and its insufficiency in addressing the dark matter problem. Recent observations indicate that WHIM, while detectable in galaxy clusters via X-rays, constitutes only a minor fraction of the mass required to maintain the gravitational cohesion of these clusters. The consensus is that WHIM cannot account for the totality of dark matter in the universe, as evidenced by the bullet cluster, which serves as a critical observational counterexample.
PREREQUISITES
