摘要：
In the first part of this article, given the intent to stay at a popular level, it has been introduced and explained briefly basic concepts of Einstein's General Relativity, Dark Matter, Dark Energy, String Theory Quantum Gravity and Extended Theories of Gravity. The core of this research is based on selecting a class of theories of gravity, which exhibits scale factor duality transformations. The starting point of this theory is the effective theory of gravity derived from Bosonic String Theory which is called tree level effective theory of gravity. It is shown that this theory can be cast in a class of theories of gravity (modified theories of Einstein's General Relativity). It is imposed that Friedman-Lemaitre-Roberton-Walker (from now on FLRW) metric be solution of this class of theories, and, using the Noether symmetry approach, it is found that the cosmological model has scale factor duality like the Pre-Big Bang cosmology of Gasperini and Veneziano.
