What is the most massive known mountain in the universe?

In the universe, there are massive structures known as galaxy clusters, which are made up of hundreds or thousands of individual galaxies held together by gravity. These clusters can contain some of the most massive objects in the universe, including the most massive known mountain, which is located in the Abell 85 galaxy cluster.

The Abell 85 galaxy cluster is located about 740 million light-years from Earth and contains a massive mountain of gas and dust that measures about 5 billion times the mass of the sun. This mountain, which is located at the center of the galaxy cluster, is so massive that it distorts the fabric of space-time, causing light to bend and giving astronomers a unique view of the distant objects behind it.

While the mountain in Abell 85 is the most massive known in the universe, it is not the only one. There are other galaxy clusters that contain massive mountains of gas and dust, some of which are still being discovered and studied by astronomers using powerful telescopes and other instruments.
