'Stupendously large' primordial black holes ruled out as a dark matter source
Phys.org ·
The Brief · written from 2 sources
- An analysis of Planck's cosmic microwave background observations finds no signature of extremely massive primordial black holes.
- The result excludes such black holes as a significant component of dark matter.
- Primordial black holes are hypothetical objects that could have formed directly from dense clumps of matter in the very early universe.
Why it matters
The result narrows the set of viable dark matter candidates and constrains models of how black holes could have formed in the early universe, which matters for science readers following cosmology and dark matter research.
Who’s affected

Primordial black holes are hypothetical objects that could have formed directly from dense clumps of matter in the very early universe. If they exist, their dramatic origins would set them apart from the black holes we see today, which form when massive stars collapse. Some…
