To get an understanding of the future evolution of irregular clusters, we can draw insights from current observations and knowledge of astrophysical processes.

Firstly, irregular clusters typically consist of loosely bound groups of galaxies that lack a well-defined central concentration. Over time, these clusters tend to undergo dynamical interactions and mergers between galaxies, which can cause the cluster to evolve.

Based on these processes, there are several possibilities for the future evolution of irregular clusters:

1. They will become less centrally concentrated and assume a roughly uniform spatial density: The dynamical interactions and mergers between galaxies will cause the cluster to become more homogeneously distributed. The effect of these interactions will gradually redistribute the galaxies throughout the cluster, resulting in a more uniform distribution of galaxies.

2. They are not yet in a dynamical equilibrium, but will likely reach it eventually: Irregular clusters are often in a state of dynamical disequilibrium, meaning that the galaxies within the cluster are still undergoing interactions and mergers. However, given enough time, these processes will gradually drive the cluster towards a state of dynamical equilibrium, where the interactions and motions of the galaxies reach a balanced state.

3. They will keep contracting until they form a supermassive black hole: While irregular clusters may experience contraction due to gravitational interactions, it is unlikely that they will collapse into a single supermassive black hole. Instead, clusters are more likely to continue evolving through interactions between galaxies, rather than collapsing into a single object.

4. They will eventually stretch into a filament: Filaments are large-scale structures in the cosmic web, composed of galaxy clusters and interconnecting galaxies. While irregular clusters can interact and merge with neighboring clusters, leading to the formation of larger structures like filaments, this process may take a significant amount of time and is influenced by various factors such as the cosmic environment and dark matter distribution.

It is important to note that the future evolution of irregular clusters is still an active area of research, and our understanding continues to improve with new observational data and theoretical models.
