 The {{w|Kuiper Belt}} is a region of the outer Solar System beyond the orbit of Neptune consisting of numerous small icy bodies, including the dwarf planets {{w|Pluto}} and {{w|Eris (dwarf planet)|Eris}}. An {{w|Oberth effect|Oberth maneuver}} is a spaceflight maneuver, specifically an engine burn performed during the flyby of a celestial body. The point of this is to optimize usable energy, because rocket burns are more effective to perform at high speeds than at low speeds. The more massive the body and the lower the altitude, the higher the flyby speed will be, and the greater the performance gain due to the Oberth effect. The theoretical way to use rocket fuel most efficiently is therefore to execute the burn during a flyby of the most massive celestial body available, as close as possible.

 An Oberth maneuver in the close vicinity of the Sun, while theoretically possible and extraordinarily effective at the speeds the spacecraft would reach, would however be very difficult to carry out in real life, because the neighborhood of the Sun is an extremely hostile environment{{Citation needed}} and the spacecraft could be incinerated during a too-close flyby.
 Cueball's argument for why the maneuver will work in real life is that it works in ''{{w|Kerbal Space Program}}'' (KSP), a sandbox spaceflight simulator game. While KSP does simulate a lot of the physics of space flight, it is (necessarily) simplistic in its modeling of orbital dynamics. For example, KSP does not do any {{w|N-body simulation}}s, so if one were flying a rocket from Earth to the moon, in the game the rocket would only be affected by Earth's gravity until it reaches a certain point where it will only be affected by the moon's gravity, unlike in real life where the rocket would feel the effects of both celestial bodies at all times. Therefore, orbits modeled using KSP would poorly reflect the actual orbital behavior of a probe traveling through the solar system on a multi-year mission involving multiple fly-by maneuvers.

 *In 2018, {{w|NASA}} launched a mission to the sun with a closest distance of only 8.5 solar radii. The {{w|Parker Solar Probe}} is using seven Venus flybys to reach its [http://parkersolarprobe.jhuapl.edu/index.php first close approach]. The maneuvers will last nearly seven years, before the real mission starts.
 *Humorously, in real life [http://news.cnet.com/8301-1023_3-57495117-93/mars-curiosity-rover-team-prefers-macs-to-pcs/ a group of NASA team members "love" to play ''Kerbal''].

-Another reason why using KSP would not inspire confidence is that many players playing the game use a 'trial-and-error' method, field testing designs and inevitably either crashing them or running out of fuel stranding the craft in deep space. Inside a game this is not a major issue as one can simply reload an earlier save with no repurcussions, but in real life this would result in expensive costs constructing new spacecraft and even loss of human life, which NASA would likely frown upon.{{Citation needed}}

 The humor in referencing KSP in the comic lies in using a simple game program to simulate complex space missions which in reality take a great number of experts to plan and implement. Fly-by maneuvers, used to minimize the fuel needed to reach a destination, need to be very carefully timed - often to within seconds - so the use of ''Kerbal Space Program'' to simulate them isn't a good enough argument for NASA to agree to implement the proposal, and implies simplistic thinking on the part of the proposer; therefore one should not say it at NASA.
