Brief and simplified suggestion to complement https://phys.org/news/2021-02-smallest-galaxies-universe-dark.html and diverse past discernments. And the many related explorations.
Characterizing galaxies through different stages of life cycles transformation and phase transitions processes would give hints and insights into many life mysteries such as:
1.0 Dark-spectra field or dark matter and energy.
2.0 Ordinary matter: non sentient and sentient
3.0 Sentient life process
4.0 How 1.0-3.0 interact such as how evolution interaction process
5.0 Interconnection phenomena between galaxies
and among many other possibilities such as relating or extrapolating, interpolating, and correlating to life as known in current galaxy, solar system, and earth.
Since the exploration cannot be done through or based on actual life cycles of galaxies (billions years life cycles), creative or innovative extrapolation, interpolation, and correlation of observable or detectable galaxies and galaxies clusters should yield meaningful information and discoveries.
