Cosmological observations in a modified theory of gravity (MOG)

Understand

Our modified gravity theory (MOG) is a gravitational theory without exotic dark matter, based on an action principle.

• MOG has been used successfully to model astrophysical phenomena such as galaxy rotation curves, galaxy cluster masses, and lensing.
• MOG may also be able to account for cosmological observations.
• We assume that the MOG point source solution can be used to describe extended distributions of matter via an appropriately modified Poisson equation.
