Question

Notice that the hot, X-ray-emitting gas (red) is not in the same place as most of the visible galaxies and most of the matter (blue). How do we think the hot gas came to be in a different place from the galaxies and most of the matter?

Answer 1

The hot, X-ray-emitting gas in galaxy clusters is thought to have come to be in a different place due to the influence of the cluster's gravity and the constant movement and interaction of the gas particles.

Step-by-step explanation:

The hot, X-ray-emitting gas that is not in the same place as most of the visible galaxies and most of the matter in galaxy clusters is thought to have come to be in a different place due to the influence of the cluster's immense gravity. The gas particles in the clusters are constantly moving and bumping against each other, causing the gas to heat up hotter and hotter. This heating process, fueled by the cluster's gravity, results in the gas shining brightly at X-ray wavelengths.
