Finding... Nothing

After 90 years of searching, likely the strongest statement that can be made in favor of the existence of Dark Matter (DM) is simiilar to the introduction to a March 2023 article published by the American Astronomical Society:

It is widely believed that dark matter (DM) constitutes the
major mass-energy component of galaxy clusters (Clowe et al.
2006) and large-scale structures of the universe (Davis et al.
1985).

 

An October 2020 article in CalTech Magazine, "Where is Dark Matter Hiding?" summarizes the state of scientific observation of DM:

Since the 1990s, scientists have been building large experiments designed to catch elusive dark matter particles, but they continue to come up empty-handed.
