Abstract

We compare the cosmological kinematics obtained via our law of linearly varying deceleration parameter (LVDP) with the kinematics obtained in the ΛCDM model. We show that the LVDP model is almost indistinguishable from the ΛCDM model up to the near future of our universe as far as the current observations are concerned, though their predictions differ tremendously into the far future.

Notes

  1. Because our main goal in this letter is to compare the LVDP and ΛCDM models, for convenience, we regard the time parameter as dimensionless by taking \(t\rightarrow \frac{t}{1~\mathrm{Gyr}}\) and indicate Gyr in parentheses, i.e., (Gyr), to remind the reader of this.
