Does WHIM solve the dark matter problem?

In summary, recent progress has been made in the direct observation of the warm-hot intergalactic medium, also known as the "whim." However, it is not enough to account for the quantity of dark matter in the universe, which is necessary to hold galaxy clusters together. This can be seen through x-rays in galaxy clusters, where the whim only makes up a small fraction of what is needed. The bullet cluster is a prime example that directly rules out this theory.

TL;DR Summary
Does the Observation of whim can solved the problem of dark matter
Direct Observation of Whim (The warm–hot intergalactic medium) has known a lot progress recently. Does whim could be enough to amount to the quantity of dark matters in the universe, therefore solving the dark matter problem? If not, why?

Short answer: no, for many reasons. First, there isn't enough of it. We can see this matter quite clearly in galaxy clusters through x-rays, and it only amounts to a small fraction of what is required to hold the galaxy clusters together.

There's lots of other reasons why this can't work, but that's the start of it. I recommend looking up the bullet cluster for a pretty direct observational example that rules this out directly.

1. What is WHIM and how does it relate to dark matter?

WHIM stands for Warm-Hot Intergalactic Medium, which is a diffuse gas that exists in the space between galaxies. It is believed that a significant portion of the missing mass in the universe, also known as dark matter, may exist in this form.

2. How does WHIM solve the dark matter problem?

WHIM is a potential solution to the dark matter problem because it is estimated to make up a large fraction of the total mass in the universe. If we can accurately measure the amount of WHIM present, it may account for the missing mass that is currently attributed to dark matter.

3. What evidence supports the existence of WHIM?

There is observational evidence for the existence of WHIM, including X-ray emissions from hot gas in galaxy clusters and absorption lines in the spectra of distant quasars. These observations suggest the presence of a significant amount of diffuse gas in the universe.

4. Are there any challenges to using WHIM to solve the dark matter problem?

While WHIM is a promising candidate for solving the dark matter problem, there are still challenges to accurately measuring and understanding its properties. This includes difficulties in detecting and studying the diffuse gas, as well as uncertainties in estimating its mass and distribution.

5. How does the existence of WHIM impact our understanding of the universe?

If WHIM is confirmed to be a significant contributor to the missing mass in the universe, it would greatly impact our understanding of the universe and its evolution. It could also provide insights into the formation and evolution of galaxies and large-scale structures in the universe.
