In this thesis, we construct the equation of motion for Bekenstein-Sandvik- Barrow-Magueijo (BSBM) lagrangian. Firstly, we consider the Friedmann-Lemaitre- Robertson Walker (FLRW) metric. We calculate Christoffel symbols, Ricci tensor, and Ricci scalar. After that, we find the Friedmann equation. Fi...
