I can speculate all I want about the nature of the universe and "reality," but such would be just speculation. I can say that our reality is like a computer simulation. I can say that our reality is like a hologram. I can say that our reality is like a dream. There are many more I-can-say's. They are speculations. As humans, we are like rabbits in that even if higher beings were to tell us the truth, we still might not understand.
