On the Relativity in Configuration Space: A Renewed Physics In Sight

The idea that possible configurations of a physical system can be represented as points in a multidimensional configuration space ${\cal C}$ is explored. The notion of spacetime, without ${\cal C}$, does not exist in this theory. Spacetime is associated with the degrees of freedom of a chosen single particle within a considered configuration, and is thus a subspace of ${\cal C}$. Finite dimensional configuration spaces of point particles, and infinite dimensional configuration spaces of branes are considered. Multidimensionality of a configuration space has for a consequence the existence of extra interactions, besides the 4D gravity, both at macroscopic and microscopic scales.
