- Title
The large-scale structure of the universe from a modified Friedmann equation.

- Abstract
In this paper, we have suggested that the late time expansion of the Universe is caused by the absorption of baby universes. This absorption leads to a modified Friedmann equation with one free parameter B replacing the cosmological constant. The late time cosmology is modified in such a way that one can obtain agreement with the measured values of the Hubble parameter H(z) for z between 0 and the value corresponding to the time of last scattering of CMB for a suitable choice of B. In this paper, we show that the modified Friedmann equation with this choice of B also describes well other aspects of the large-scale structure of the Universe.
