Description

In this talk, I will discuss how a newly proposed gravitational theory (arXiv: 2007:00082) could lead to a solution for the dark matter problem by reducing to Milgrom’s Modified Newtonian Dynamics at the scale of galaxies and to the LambdaCDM model on cosmological scales. I will show that it (i) leads to correct gravitational lensing on galactic scales, (ii) propagates tensor modes at the speed of light, and (iii) gives excellent fits to the Cosmic Microwave Background anisotropies and the large-scale structure power spectrum.
