The comparison of redshift-distance relationship for high and low-redshift supernovae has revealed the surprising transition of Universe’s expansion from deceleration to acceleration. As compared to local supernovae, remote supernovae are further away than expected. The expansion rate obtained for local supernovae is higher with low redshifts as compared to the expansion rate obtained for remote supernovae with high redshifts. Since observed redshifts provide an estimate of recession velocities in order to determine the expansion rate (km/s/Mpc) of the local and the remote Universe, therefore, it is very disturbing to find that low recession velocities indicate acceleration (faster rate of expansion), whereas high recession velocities indicate deceleration (slower rate of expansion). In this paper I unravel an undiscovered aspect that perfectly mimics cosmic acceleration. I show in this paper that remote structures began expanding into the Universe before the expansion got initiated for the local structures, for this reason, remote structures are not only further away than expected, but they also happen to yield a slower rate of expansion as compared to the expansion rate obtained for the local structures. The analysis is based on the redshift-distance relationship plotted for 580 type Ia supernovae from the Supernova Cosmology Project, 7 additional high-redshift type Ia supernovae discovered through the Advanced Camera for Surveys on the Hubble Space Telescope from the Great Observatories Origins Deep Survey Treasury program, and 1 additional very high-redshift type Ia supernova discovered with Wide Field and Planetary Camera 2 on the Hubble Space Telescope. The results obtained by the High-Z Supernova Search Team through observations of type Ia supernovae have also been analysed.
