Microscopic Theory of the Universe

Micro and Macro What is micro and what is macro? Personally, I think everything is false. Micro is macro and macro is micro. For the largest universe, if you jump out of the universe and look at the universe, it will be a different world. If you shrink down to the smallest atom, one atom is another world. This book looks at the macro world from a micro perspective, and at the same time guesses the micro world from a macro perspective.
