I will discuss some aspects of the concept of "point" in quantum gravity,
using mainly the tool of noncommutative geometry. I will argue that at Planck's
distances the very concept of point may lose its meaning. I will then show how,
using the spectral action and a high momenta expansion, the connections between
points, as probed by boson propagators, vanish. This discussion follows closely
