The problem with general relativity is that it is accurate enough when applied at larger scales, but breaks down at small scales. I have not spent my life studying theoretical physics, but I have an interest and possess the intellect to at least grasp the context of published papers. The problem with general relativity is it is based on a three dimensional universe, yet the singularity can only be renormalized with an infinite number of interconnected points across multiple universes. This has been dubbed [String Theory.](https://www.forbes.com/sites/startswithabang/2020/02/26/why-string-theory-is-both-a-dream-and-a-nightmare/?sh=17cbf4e83b1d) but it as well has become as problematic as general relativity.
