Only 5% of the universe consists of visible matter such as atoms and light, including everything from individuals to celestial bodies

The bulk of the cosmos consists of two perplexing components: dark energy, constituting 68%, and dark matter, which makes up approximately 27%

Dark matter, detected indirectly through galaxies' excessive rotation, emits no light, baffling astronomers for decades

The prevailing theory of "Cold Dark Matter" (CDM) suggests that it consists of slow-moving particles primarily influenced by gravitational interactions

Yet, recent anomalies challenge Cold Dark Matter's dominance, prompting a shift towards "Self-Interacting Dark Matter" (SIDM)

SIDM proposes a hidden dark universe with particles and forces parallel to normal matter, potentially with its "Dark Big Bang"

Despite its mysteries, dark matter's behaviour helps reproduce large-scale structures observed in the universe

Anomalies in galaxy structure and satellite counts hint at SIDM's superiority over CDM

New experiments, like ForwArd Search ExpeRiment (FASER) and Super CDMS, may uncover the secrets of dark matter
