The process of using math to understand our world is often seen in physics as it allows us to reach beyond our current levels of understanding, but the actual world is a gray area when it comes to interpretation and description.
The relationship between the abstract reality of quantum mechanics and our perceived reality is philosophically and metaphysically interesting. Further proof of the many worlds interpretation of quantum mechanics may have significant implications and raise important questions about the nature of reality.
The modern math and physics theories have become detached from reality to such an extent that they are beyond our comprehension, and it is a common misinterpretation that math formulas and theories are not useful unless they represent the object they are referring to, but they often have deep connections to the physical world.
The idea that we may be living in a multidimensional world, where space and time are merely constructs, is explored through mathematical structures such as hypergraphs. This could lead to a new understanding of physical matter and the potential for physics to be changed in ways we do not yet comprehend.
The perturbative approach to string theory has not provided a comprehensive solution to the mapping of a consistent physical world in 10 dimensions to one in four dimensions. The hope has always been that there will be a deeper and better understanding of what string theory is that would actually go beyond this perturbative expansion and which would generalize this.
This podcast episode delves into Einstein's inquiry on the direction of time, and how our brains understand it through entropy.
