Part 8/10:
A third proposition speaks to the possibility that our universe could have emerged from "nothing" in a quantum mechanical sense. Quantum fluctuations, which occur even in empty space, could potentially lead to the creation of space-time itself. These fluctuations allow particles to appear and vanish in a manner consistent with the laws of physics, paving the way for the spontaneous emergence of a universe from a small bubble that expands rapidly enough to establish an irreversible cosmic existence.
This concept was mathematically supported by three Chinese physicists in 2014, positing that given enough iterations of quantum fluctuations, a universe may inevitably emerge, thus challenging our understanding of existence itself.
