That is faulty, as it equates space with our universe. Rather, our universe was born, exists, and will die within space, which is infinite. As for “time”, it exists only in the human mind.In the classical BB model there is no space-time before, so your claim "there was an intensification of quantum energy in a small region of space" is meaningless for three reasons
- No space, so no "small region of space".
- No time, so an "intensification" couldn't happen.
- Even in the presence of space-time "an intensification of quantum energy in a small region of space" is basically word salad.
