Minimal Asymmetric Expansion of the Universe: A Friedmann-Sasaki-Randers Spacetime Framework Incorporating Dark Matter and Dark Energy
In this work, we investigate the structure of the gravitational field and the Friedmann equations in a Sasaki–Randers spacetime, incorporating dark matter and dark energy within the Lorentz tangent bundle of spacetime. Additional terms arising in the geodesic equations and the Friedmann equations modify and generalize...
