Implications of Graviton-Graviton
Interactions for Dark Matter
Alexandre Deur

Our present understanding of the universe requires the existence of dark
matter and dark energy. In this talk, we will first present the
observation leading to the dark matter hypothesis. Then we will discuss a
natural mechanism that could make exotic dark matter and possibly dark
energy unnecessary. Graviton-graviton interactions increase the
gravitational binding of matter. This increase, for large massive systems
such as galaxies, may be large enough to make exotic dark matter
superfluous. Within a weak field approximation we compute the effect on
the rotation curves of galaxies and find the correct magnitude and
distribution without the need for arbitrary parameters or additional
exotic particles.
