I would like to introduce some of the ideas that are put forward to explain this unsettling phenomenon. I will show why and how the path of modified gravity theories is taken by some cosmologist, rather than simply considering the cosmological constant. Then, I wish to present a novel approach, the effective field theory of dark energy. This allows one to study in a unified way all modified gravity models containing a single scalar field added to Einstein's equations. I would like to also show how a rich phenomenology of large scale structures observables arises. I would like to finish by highlighting how certain correlations between these observables allows one to discard between modified gravity theories or as to the type of dark energy embedded within these theories.</span></p>
