[T]ime is much more elastic than our intuition of this rigid passage... The time interval between one point and another... depends on where you are. - Carlo Rovelli

I argue that the best strategy for understanding quantum gravity is to build a picture of the physical world where the notion of time plays no role at all.

The new coherent picture is not yet available. With all their immense empirical success, G(eneral)R(elativity) and Q(uantum)M(echanics) have left us with an understanding of the physical world which is unclear and badly fragmented. At the foundations of physics there is today confusion and incoherence.

If we formulate the fundamental theory of nature in a timeless language, we have then the problem of recovering the familiar notion of time.
