Introduction: Ever since I first learned about fractions as a child, I was always heavily agitated by the fact that every time I would ask my teacher about dividing by zero, or have a calculator perform a equation where a non-zero number was divided by zero, I would just be told there was no solution. I wondered for years about why there simply was no practical way to express a number divided by zero, until I learned about something strangely similar to dividing a number by zero, being black holes, or a gravitational singularity (a single point in space with a certain mass, equating to a density where the mass of the object is divided by zero). Just like dividing by zero, black holes are usually represented as an undefined point in…show more content…
A counterargument could be immediately made that black holes do have a volume, but for clarification, this is in terms of its’ singularity, not its’ event horizon (or the critical radius), which is the black part of the hole that light does not escape from, as it is the point in which light can no longer escape, as the escape velocity (the speed required to break free of an object’s gravity, according to physlink.com) is greater than the speed of light. Now that this is established, representing the “infinite” density of a black hole is difficult to understand, similarly in terms of the function 1/x, because like how the x- value on the graph approaches the asymptote of zero on the x- axis from positive infinity, the y-value gradually leaves the asymptote of zero on the y- axis to approach infinity, being not the largest possible number, but instead a filled space that has no bounds, such as a star that is shining light into all directions in space forever, therefore filing this ongoing void with light. That is infinity, so in terms of this essay, the light could be represented as 1/∞. If the light were to be replaced with mass, the volume of said mass would effectively be the opposite of a black hole, being an infinite number of some sort, with the density being calculated by dividing it’s mass by infinity of some sort, representing it’s volume. In simple fractions, they could likely be expressed as a circle or some other shape split into
