I recently watched curiosity and i have been having a hard time grasping how it describes the creation of our universe. As i understood the theory is that the laws of our universe say that a particle of subatomic or less size can pop in and out of existence and so the universe itself could do the same because it was so incredibly small and the laws of our universe say it is possible it could do so. My question is why would the laws of the universe apply to a lack of existence? My understanding is that the universe didn't exist and neither did anything else then it came into existence spontaneously with no time before it. So i would think the laws that govern our universe must therefore have applied themselves to the lack of existence for the universe to be able to pop into existence spontaneously like that, which would only be possible with the laws we now have discovered in place despite the lack of an existence for them to govern.
