  If gravity were an emergent phenomenon, some relativistic as well as
non-relativistic speculations claim it is, then a certain emergence time scale
tau_? would characterize it. We argue that the available experimental evidences
have poor time resolution regarding how immediate the creation of Newton field
of accelerated mass sources is. Although the concrete theoretical model of
gravity's `laziness' is missing, the concept and the scale tau_? ~ 1ms, rooted
in an extrapolation of spontaneous wave function collapse theory, might be
tested directly in reachable experiments.
