# Monologue of a graviton in identity crisis. Or on Alternative Theories of Gravity. (In Spanish)

@article{MartnMoruno2018MonologueOA, title={Monologue of a graviton in identity crisis. Or on Alternative Theories of Gravity. (In Spanish)}, author={Prado Mart{\'i}n-Moruno}, journal={arXiv: Popular Physics}, year={2018} }

The era of high precision Cosmology has shown our ignorance about the composition of the Universe. In this context, there has been a renewed interest on Alternative Theories of Gravity. Through the experience of a graviton measured by the LIGO collaboration, we shall understand the conceptual framework of those theories. They provide us with a theoretical construction where we can contrast the predictions of General Relativity and a possible scenario to describe the accelerated expansion of our… Expand

Abstract Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of General Relativity at infrared and ultraviolet scales. They are an approach that, by preserving the… Expand

Horndeski theories self-tuning to a de Sitter vacuum

We consider Horndeski cosmological models able to screen the vacuum energy coming from any field theory assuming that after this screening the space should be in a de Sitter vacuum with a particular… Expand

Tests of general relativity at the post-Newtonian level have reached high precision, including the light defl ection the Shapiro time delay, the perihelion advance of Mercury, and the Nordtvedt effect in lunar motion. Expand

Sequestering the Standard Model Vacuum Energy

We propose a very simple reformulation of general relativity, which completely sequesters from gravity all of the vacuum energy from a matter sector, including all loop corrections and renders all… Expand

The results eliminate any late-universe application of any cosmologically viable, well motivated gravity theory which predicts a variable GW speed at low redshift, and extend to any other gravity theory predicting varying c_{g} such as Einstein-Aether, Hořava gravity, Generalized Proca, tensor-vector-scalar gravity (TEVES), and other MOND-like gravities.
