Review on $f(Q)$ Gravity

Understand

Recent years have witnessed a rise in interest in the geometrical trinity of General Relativity and its extensions.

• This interest has been fuelled by novel insights into the nature of gravity, the possibility to address computational and conceptual questions -- such as the determination of black hole entropy or the definition of gravitational energy-momentum -- from a new perspective.
• In particular, $f(Q)$ gravity has also inspired numerous works on black holes, wormholes, and cosmology.
• In the latter case, $f(Q)$ models have the potential to elucidate phenomena in both early and late-time cosmology without necessitating the inclusion of dark energy, the inflaton field, or dark matter.
