Complexity in Dark Matter and Unknown Forces
The universe contains a vast diversity of unknown elements that have yet to be discovered. It is possible that pockets of complexity similar to life on Earth exist within dark matter, which may evolve in different ways due to unique conditions and interactions. The conditions that give rise to life and complexity are complex and unlikely, but it is worth investigating if there are other forces that exist in the dark matter sector. Dark matter may have its own forces and interactions, different from those in the standard model of physics. There could also be other weak forces and particles within our sector that have not been discovered yet, prompting the construction of large colliders to explore higher energy levels and shorter distance scales. Thus, the existence of unknown forces and elements in both dark matter and our sector signifies that there is much about the universe that remains to be explored and understood.
