Abstract: | Pathria (1972) has shown, for a pressureless closed Universe, that it is inside a black (or white) hole. We show now, that the Universe
with a cosmic pressure obeying Einstein’s field equations, can be inside a white-hole. In the closed case, a positive cosmological
constant does the job; for the flat and open cases, the condition we find is not verified for the very early Universe, but
with the growth of the scale-factor, the condition will be certainly fulfilled for a positive cosmological constant, after
some time. We associate the absolute temperature of the Universe, with the temperature of the corresponding white-hole. |
