Kerbin is actually hollow.

[Guest]

Have you ever wondered why KSC is the only building that has signs of population? Have you ever wondered why Kerbin has no signs of intelligent life (except the KSC and Island Airport)? Wondered why do you get these contracts asking me to take reports at random places if kerbals even have the technology to get to space? Well, today's your lucky day. We here at Aperture Science have figured out the conspiracy.

KERBIN IS HOLLOW.

Now you may think. What evidence do I have to support this theory? Well, you can check how the Kerbal Astronomy Society describes the Mun:

The Mun's discovery is widely regarded as one of the more important breakthroughs of Kerbal evolution. Granted it didn’t happen all that long ago, but its still fair to say that Kerbals are wiser and more evolved now than they were back then.

Hmm. How could the discovery of the Mun be recent if kerbals had spent their entire existence on the outer shell of the planet? You cannot avoid noticing such thing on the sky, be it daytime or nighttime. So we have two options: Either kerbals' species is very recent, or they've been somehow unable to see the sky. The first option is obviously the less logical, since in order for that to happen the mutation rate at Kerbin would have to be very high, speeding up the evolutionary process, but also killing most of the organisms, therefore it's illogical. So, kerbals have been unable to see the Mun for some reason.

Ok. So we've seen the description of the Mun. What else can be noticed very easily in Kerbin's skies? Kerbol (Sun). Let's read its description by the KAS:

The Sun is the most well known object in the daytime sky. Scientists have noted a particular burning sensation and potential loss of vision if it is stared at for long periods of time. This is especially important to keep in mind considering the effect shiny objects have on the average Kerbal.

So Kerbol is the most well known object in daytime sky, yet kerbals have been unable to see the Mun, which can be seen in both daytime sky and nighttime sky. Therefore, the Mun was constantly blocked while there was a huge source of light visible to kerbals.

Ok. So, for the largest part of history, kerbals could only see Kerbol, the most well known object in the daytime sky, yet the discovery of the Mun is very recent. What could have caused this?

Well, what we've been told by the game is a lie. Kerbin is not a planet. It's a hollow sphere.

And how would such sphere work? Since the only noticeable object in the "sky" is Kerbol, then there must be a large source of light at the middle of the sphere's inside side, which is where kerbals have started their history. Then we have two options: either it was kept on the entire time, which could explain the lack of kerbal sleep, or it was programmed to periodically change its status. Since scientists have noted a potential loss of vision if stared at for long periods of time, it probably was a programmed light.

How would the day/night work? There are also two options. Either Kerbol is a rotating spotlight (that could create time zones) or it's static and toggles itself on and off periodically. If it was a static object, then it probably would never lead kerbals into thinking that they could be inside a sphere. If it was a rotating spotlight, then maybe kerbals could have spotted the structure of the spotlight, knowing that something was wrong. It could potentially inspire them into drilling the ground to look for answers, eventually resulting in the discovery of the outside.

So far, we know this: Kerbin is a hollow sphere with the great majority of the kerbal species living inside it. It has timezones, so half of the inside is day and the half is night, creating time zones.

Right. But what could explain the artifacts that we can find on the outer shell of kerbin, such as the Island Airbase and the ancient kerbal pyramids?

They were previous attempts at establishing an outpost on the outer shell. As kerbals weren't adapted to the outside, most of the outsiders died, leaving their buildings abandoned to the environment, losing the knowledge that there was an outside. Kerbals evolved, and eventually developed spacesuits, in order to get protected from the hazardous environment that is Kerbin's outer shell, managing to keep the KSC in good shape and keeping it as kerbals' only connection to the outer shell, since building such thing is very expensive.

So we've been hidden from the truth the entire time, from 0.7 to 1.0.5.

But... is Kerbin the only sphere? What's its origin?

All the planets are spheres with species inside them, each species with their potential to get outside. Some successful, some not. Currently, kerbals are the only species to have sucessfully managed to get out of their sphere, and the krakens of Bop have already tried to, but the only one that dared to get outside died when exposed to the vacuum of space. And what's the origin of the spheres? They're alien artifacts, made by an unknown species that has a well-protected space station, Jool. It communicates to the spheres' systems via the monoliths, using flying saucers to fly from sphere to sphere. Jool has weaponry against ships in order to hide the true architects of the sphere, shooting down every unknown object that dares to dive into its atmosphere.

And that's it, ladies and gentlemen. Kerbin's not a planet. Eve's not a planet. Duna's not a planet. No Kerbol planet is a planet. They're hollow alien spheres.

Spread the truth.

Crazy and grasping at shreds of evidence.

I love it.

I will spread the truth, for I have done the same for Futurama.
