Primordial Black Hole
Cosmology & UniverseSpeculative Hypothesis
Definition
A hypothesised black hole formed from density fluctuations in the very early Universe rather than from a star.
Scientific overview
If the early Universe contained sufficiently dense regions, they could have collapsed directly into black holes of a wide range of masses. Primordial black holes have been proposed as a candidate for some or all of the dark matter.
Open questions
- Do primordial black holes exist at all?
- Could they make up part of the dark matter?
