It's clear that mathematics is the language of physics . Mathematics is a tool for constructing many many different realities . Imagine that god decided to create the universe . He used mathematics to design the laws . This is similar to using a programming language to write a program . However , if you write a program in a specific programming language on a piece of paper , Nothing will be done , the program would be useless . You actually need a computer architecture (CPU , physical memory etc ) and an operating system . In order to actually construct the universe , Where and how does god write the reality that he have designed ? In other words , What is it that transforms the fundamental equations (e.g M theory equations or whatever ) into physical reality ?
In response to comments , That's what my research have uncovered . If I was able to invent a new universe mathematically on paper in which intelligent entities of some sort can exist , Have I just discovered some sort of aliens exist in another universe that's actually real or is this universe completely fictional and a sort of mechanism is missing that's is required for making that universe real? If there is no way that I can make certain using physical means that the universe that I've constructed actually exist then it's meaningless to say whether it's real or not . I've actually discovered a mathematically consistent universe that's as real as our universe for take an intelligent being on the other universe he'll too wonder if our universe is real even though he can't do experiments to show that
