Contribution Of Blackhole Entropy Towards Acceleration Of The Universe
A. M. Haruar Rashid, A. L. Choudhury
In a recent model Choudhury proposed that a collapsing matter generates an adiabatic pressure which can be used to explain the acceleration of the physical universe under certain a…
Influence Of Collapsing Matter On The Enveloping Expanding Universe
A. Latif Choudhury
Using a collapsing matter model at the center of an expanding universe as described by Weinberg we assume a special type of generated pressure. This pressure transmits into the sur…
Influence On The Physical Universe By Wormhole Generated Extra Dimensional space
A. L. Choudhury
We use the Gu-Huang model for a special case when the universe is seven dimensional. In the core of extra dimension we place a modified Gidding-Strominger wormhole. This wormhole i…
A wormhole-generated physical universe with refined approximation
A. L. Choudhury
We improved the approximation of the model of the wormhole generated physical universe constructed by Choudhury and Pendharkar. We show here that the negative pressure of the unphy…
Wormhole-generated physical universe
A. L. Choudhury, Hemant Pendharkar
We constructed a model where the central core of the universe is a modified Gidding-Strominger wormhole and surrounding the core is a Robertson-Walker Universe with k=0. They are s…
