Description

Symmetric Special Relativity (SSR) aims to study gravitation from the perspective of a new kinematic scalar invariant: a minimum speed. In this context, given that the speed of light represents nature's maximum kinematic regime ($c \approx 3 \times 10^8$ m/s), the minimum speed would correspond to a minimum velocity regime of $v \approx 10^{-14}$ m/s. Formulating a theory of relativity based on these two invariants leads to Symmetric Special Relativity, which has implications for dark energy, vacuum energy, and dark matter. Recently, SSR has been applied to explain certain effects associated with primordial gravitational waves linked to the standard cosmological model of the initial singularity. This scenario is promising, as gravitational wave detectors such as LIGO and VIRGO may soon provide realistic estimates regarding this proposal and the studies recently conducted [1-3].
