Abstract: It is now, generally, believed that the presence of some form of dark matter is essential to explain the flat rotation curves of galaxies, and anomalous large velocities of galaxies in the clusters and superclusters. This dark matter turns out to be too elusive and, so far, there is no direct evidence for such matter although there is a large variety of candidates proposed by theoretical models. One would expect that the existence of vast amount of dark matter would lead to the formation of some dark galaxies or clusters which could be seen by gravitational lensing events.This could serve as a direct evidence for dark matter. However, so far, there is no conclusive lensing event pertaining to that. In spite of absence of any direct evidence, there is a consensus among physicists in favour of some form of non-baryonic dark matter. In this paper, we take a different viewpoint and would like to view dark matter as an emergent phenomenon - very much like many such phenomena known in condensed matter systems. We propose here a novel mechanism involving Voids, which can, in principle give rise to a difference between the gravitational and the inertial mass, and thereby, create effects similar to the dark matter.
