just the fact that there are so many quantum fields and they interact with each other in intricate and probabilistic ways, makes me think we are inside of a larger machine and we are only seeing a slice of it. It’s like flatlanders trying to understand why they see lines appear and disappear as a cube passes through their plane. We’ll probably never know the full extent of the universe, in the same sense as our far descendents who may never know the extent of the observable universe we know today once all the galaxies disappear, assuming this information isn’t able to survive for 300 billion years.
