Gravitational Origin of Dark Matter

Understand

Observational evidence for the existence of Dark Matter is limited to its gravitational effects.

• The extensive program for dedicated searches has yielded null results so far, challenging the most popular models.
• Here we propose that this is the case because the very existence of cold Dark Matter is a manifestation of gravity itself.
• The consistent bimetric theory of gravity, the only known ghost-free extension of General Relativity involving a massless and a massive spin-2 field, automatically contains a perfect Dark Matter candidate.
