Could a gravity inversion exist within the Hollow Earth of Legendary's Monsterverse?

Abstract

One of the most popular movie franchises of late is Legendary's Monsterverse as is evidenced by the gross earnings of the series recently surpassing the two and a half billion dollar mark with the release of $\it{Godzilla X Kong}$. As is typical with many movies of this genre, in order to enjoy them one must suspend their disbelief when it comes to the laws of physics. While there are a plethora of examples of violations of basic principles (the square-cube law being the prime example) the idea of a "gravity inversion" occurring inside of the "Hollow Earth" is among the most debated as well as the most relevant to the storylines of the recent movies. The intent of this paper is to show that, while typical scientific arguments refuting the possibility of such an inversion are definitely completely correct, a slight modification of the conditions assumed to exist inside the planet in these arguments may allow for the inversion to actually occur.
