Query: Wormhole-generated physical universe   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 separated by a thin wall which does not allow the
content of the inner core to travel to the outer universe. But this wall allows
the pressure of the inner core to be transferred to the outer physical
universe. Assuming that the fluid density of the physical universe is
practically independent of time, we have calculated the Hubble constant and the
deacceleration parameter, qo, of the physical universe at the present time. The
Hubble constant comes out to be positive, whereas qo becomes negative. The
negative signature of this deacceleration parameter conforms to present
experimental data.
