Abstract Primordial Black Holes (PBHs) are a viable candidate to comprise some or all of the
dark matter and provide a unique window into the high-energy physics of the early universe.
This white paper discusses the scientific motivation, current status, and future reach of
observational searches for PBHs. Future observational facilities supported by DOE, NSF,
and NASA will provide unprecedented sensitivity to PBHs. However, devoted analysis
pipelines and theoretical modeling are required to fully leverage these novel data. The�…
