Astrophysicists Cross Another Dark Matter Candidate Off Their List: Stupendously Large Black Holes

Astrophysicists are leaving no stone unturned in their search for what dark matter is. Different particles have been proposed, like WIMPs and axions.

Key points

• Hypothetical rimordial black holes have also been proposed.
• But there's another less well-known candidate, SLABs or Stupendously Large Black holes, a sub-type of primordial black holes.
• Alas, SLABs can't account for dark matter either, according to new research.
