What did the universe originally consist of before the big bang?

A natural scenario, that is not yet a scientific theory but is consistent with all current knowledge, explains the origin of our universe:
At first, the universe was pure vacuum ("nothing"). By means of a random quantum fluctuation the universe 'tunnelled" from pure vacuum to what is called a false vacuum, a region of space that contains no matter or radiation but is not quite nothing.
The space inside a bubble of false vacuum is curved, or warped, and a small amount of energy is stored in that curvature. This ostensible violation of energy conservation is allowed by the Heisenberg uncertainty principle for sufficiently small time intervals. The bubble then inflated exponentially and its curvature energy transformed into matter and radiation. Inflation stopped and the more linear big bang expansion commenced.
