I will discuss the most general covariant, ghost-free, higher derivative extension of General Relativity which may be able to render  gravity asymptotically free in the deep ultra-violet, while recovering the Newtonian gravitational potential in the far infrared. Such a construction has fundamental consequences the way we think about gravity at short distances and times.
