Assumption:Mathematical existence = physical existence.Evidence:Unreasonalbe effectiveness of math in physics.Answer Wheeler/Hawking question why theses equations, not others?In this universe the properties of nature are different or may not even exist in some universes!-Hello Bob,......
Evidence: Experimental support for unitary physics. AdS/CFT correspondence suggests that even quantum gravity is unitary. Dechonerence experimentally verified. Mathmatically, this is the simplest model.
This means that any universe you can conceive of exists, somewhere/somewhen. One where your President, died at birth, became a Teacher, serial killer, journalist, etc.
Level 4: Other mathematical Structures.
Features: Different funamental equations of physics.
Assumption: Mathematical existence = physical existence.
Evidence: Unreasonalbe effectiveness of math in physics. Answer Wheeler/Hawking question "why theses equations, not others?"
In this universe the properties of nature are different or may not even exist in some universes!
Hello Bob, here language plays its own game. The very word uni verse stands for the only one consisting of all diversified. Uni - one. Now we have started identifying other universes. So our universe is for the physical side only. Then other universes meant for mind, spirit, soul etc are to be framed. Such concepts are already there in Hindu scriptures known as different 'LOGAS'. Just at present that thing is understood by the scientists based on a different scientific approach. Yet many secrets of this entire cosmos have to be brought out. Let us wait and see and enjoy.
