Compared to the conventional solution (95), the result in (104) is much more complicated, and we can see that not only H but also [phi]' plays an important role in tunneling process, which means the quantum vacuum fluctuation also affects the creation of the Universe.

Ayala said the Big Bang was a vacuum fluctuation. Sartre said there was no angel and no vacuum.
It came into existence because natural law required it to do so, in Professor Tryon's 'vacuum fluctuation'.
THE universe could end at any moment not with a huge explosion but with a "vacuum fluctuation," it was revealed yesterday.
Vacuum fluctuation is a consequence of the basic principle that in a quantum universe nothing is certain.

When a vacuum fluctuation with local energy density above its equilibrium point is considered between x and x', [DELTA]x (i.e., the proper distance) grows.
Quantum vacuum fluctuation, one of the concepts of the device, is an effect in which the particles are created in the vacuum of space spontaneously, before going back to the non-existent state in a span of one minute.
Given that the answer to exotic material for practical propulsion applications is somewhere in between vacuum fluctuation in curved space-time and scalar fields non-minimally coupled to gravity, Ginzburg-Landau (GL) scalar fields associated with superconductor junctions could present themselves as a medium for studying the interactions among energy fluctuations, cosmological scalar fields, and gravity.
