A Does WHIM solve the dark matter problem?

AI Thread Summary
Recent observations of the warm-hot intergalactic medium (WHIM) have advanced, but it is insufficient to account for the total amount of dark matter needed in the universe. WHIM is observable in galaxy clusters via X-rays, yet it constitutes only a small fraction of the mass required to maintain the stability of these clusters. The consensus is that WHIM cannot solve the dark matter problem due to its limited quantity. Further evidence, such as the bullet cluster, directly contradicts the idea that WHIM could fulfill the role of dark matter. Thus, WHIM does not provide a viable solution to the dark matter issue.

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.

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
