Earth

## Description

Earth is the third planet from the Sun, and the densest and fifth largest of the eight planets in the Solar System. It is also the largest of the Solar Systems four terrestrial planets. Its alternative names are the World, the Blue Planet, The Blue Marble, by the Greek goddess of the Earth, Gaia, or by its Latin name Terra. Its astronomical symbols are ⊕ and ♁

**Warning, the following may contain spoilers.**
The planet is a major plot point for the series, **For Artificial**: Vizzy Gatemen's main motivation is trying to get to Earth, and to try and exterminate humanity, as well as getting revenge for the countless killed by them. This was due because of Malfunction, though she still kept some of her scornful hatred of humanity even after realizing she couldn't make it to Earth. Caleb talks about Earth briefly in the show, how its the headquarters for most if not every business in the Galaxy, and how life is there.

For Sandman: The series revolves around the struggle to get off Avalon and away from Company influence; one idea being Earth. Vizzy and Felix are gathering money to buy a ride to Earth throughout the story. While they do make it, Felix never does, as he kills himself trying to take down Bail Rigel, though failing. Its revealed that he was using a double and the real Felix boarded with the double. And eventually he got to earth and captured Rigel, torturing him by killing him over and over again.

Earth has one naturally permanent satellite, The Moon (Latin name: Luna). It is the fifth-largest natural satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that orbits it. The Earth also interacts with other planetary objects, such as the Sun and Moon. At present, the Earth orbits the Sun once every 366.26 times it rotates about its own axis, which equals to 365.26 solar days, or one sidereal year. Earth also sports various man-made satellites and structures, most crucial of which being the International Space Station (abbreviated ISS), which has now quadrupled in size to accommodate the vast amount of traffic entering the station, as it is now a hub of transportation in and out of Earth and the Solar System at large.

Earth formed 4.54 billion years ago, and life appeared on its surface within one billion years. The planet is home to millions of species, including humans. Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with Earth's magnetic field, blocks harmful solar radiation, permitting life on land. The physical properties of the Earth, as well as its geological history and orbit, have allowed life to persist during this period. Estimates on how much longer the planet will to be able to continue to support life range from a mere 500 million years, to as long as 2.3 billion years.

## History

Note that there is very little information about the planet other than information already known in real life. Earth is mentioned very rarely in the series, and the following may entirely be speculation or based on knowledge already known. (Ordered by importance)

### Creation of Robots

In the late 2000's, the corporation Theldore , created the very first commercial robot, used for various tasks -- most of which industrious. Robots came in all forms, as servants, as construction workers, excavators, miners, demolition, storage, emergency services, et cetera. Later these models were improved until they were branded under the name Worker Robots, and they eventually were used in the frontier of space to create massive gates between systems. Alongside the invention of the Tachyon, robots worked well in the grueling conditions of faster than light travel, as unlike their fragile human counterparts, they were more resistant to the intense pressure and speed of the craft traveling at intense speeds, and could survive the trip towards other stars.

They were used to create the gates between systems, and connected earth to its nearest system, Alpha Centauri (or the Centauri System). Robots would be first manmade creation to set foot on another world and create a colony to sustain not only humanity, but themselves. Some robots overtime would keep selective memories and learn from them, alongside gaining other traits of intelligence and self-awareness. This would sometimes result in robots rebelling against humans. What humans called programing, it called slavery. And some ran off to either form their own societies far from human influence, or to violently rebel against the humans, while gaining support for it, with other robots.

The RECO PMC was formed to counteract this threat and with special government permission was authorized to hunt down and either exterminate the threat, or confiscate it for a memory wipe. All robots, regardless of intelligence were given a mandatory weekly memory wipe, to remove any possible chance of free thought amongst robots, this became the optimal way to contain the robot threat, though it was harder for the ones who were in hiding. So the company invented Reaper Drones (otherwise known as Disassembly Drones), exterminate the robots, directly placing a deficiency to make them seek out the oil inside the robots or die of overheating. However they were only useful on a handful of occasions, and PMC's were simply more effective. Reaper Drones were decommissioned once the last of the Robots who were rebelling on Typherous were gone.

### Invention of the Gate

Gates are essentially another name for a wormhole between two points (planetary systems), they are held open by Casimir Energy, (or antimatter). Gates are the fastest possible way for humans to travel between two points, and is instantaneous. The gates are placed in the general direction of the system relative to its place in the sky from earth.

Gates were built by robots, who are the only ones capable of withstanding the immense speed and force of going faster than light -- as well as being maintained by the robots.

### Earth Expansionism

A policy of expansionism, fueled by the greed and curiosity of finding riches and wealth amongst the stars, was enacted and caused humanity's reach across the galaxy to extend a great distance. With the farthest planet from earth and farthest in humanity's empire being Ordvashem: a frontier planet, which has been completely ruined by constant war on the planet, with it apparently being home to various small human nations mixed with native alien nations. Expansionism also brought with it a great effort for exploration and discovery, with an estimated 10,000 planets being discovered in only the first year of exploration and expansion. However only 1% of all planets explored by humanity are sustainable for life, with an even lower 0.1% being suitable or habitable for humans. However this did not deter people who wanted inhabit thoughs 1% planets that were habitable for alien life.

Though these worlds were unsuitable for a reason, worlds inhabited by humanity are inhabited for a reason: they are the right mix of gravity, pressure, and factors that are similar to earths. Planets that habitable for other forms of life, are suitable only for those forms, and not humans. They could have too little gravity, too much gravity, or are simply not even a planet. It didn't stop people from trying to do so anyway. The effects of humans living on a planet with low gravity or high gravity will cause the human body to adapt to the environment, weakening bones or being crushed by heavy gravity. On a heavy gravity planet, any fall can be fatal and humans would need to heavily built and quadrupedal (or more), to ensure a stable gait and low center of gravity.

Some humans who lived on planets with heavy gravity looked completely different to those who lived on suitable planets or even low gravity planets, most looked more alien than human and were shunned as outcasts from human society. While people who lived in low gravity were lankier and taller, developed osteoporosis, muscle atrophy, and physically could not survive on planets with higher gravities (like Earth) These flimsy humans were well suited as well to zero-gravity environments as well, the colony on Ceres rotates rapidly to simulate gravity on the dwarf planet.

Some humans were forcefully experimented on, either by aliens or by other humans, to test if humans could survive on these unsuitable planets in different ways. They invented humans that could float in dense atmospheres, humans that walked on all fours, as well as three legs, et cetera. These twisted versions of humanity were turned into thousands of bizarre subspecies, divided and differentiated beyond recognition. The majority of these subspecies would become wild and come to inhabit the planets they were experimented on. However they were killed off before anyone could find out they existed.

### Terraforming of Mars and the Systems war

While humanity was expanding beyond the stars, across the gulf of space; Mars was being terraformed into a green planet. It took centuries to terraform the Red Planet. First they created giant magnetic shields between Mars and the Sun, to stop the sun from striping the atmosphere of the planet, and allowing the planet to trap more heat and warm its climate to make it habitable. Next they took the melted ice from the polar ice caps, as well as from ice comets and placed the water on the surface of the planet to make oceans. Trillions of Cyanobacteria's were added into the water of Mars, which began photosynthesizing and producing oxygen on the planet. Nitrogen would be strategically spread into the oceans of Mars to help the bacteria to create nutrients that can be used by other living beings.

The first steps on Mars were not preformed by an astronaut, but rather by barefoot children on lush, green grass. Mars after a few centuries was the first planet in human history to have been terraformed and turned into a habitable world for humans. People on mars developed their own separate cultures and identity, separate from Earth. The low gravity of the planet also made the Martians tall and spindly, and they became almost a different species to the Earthlings. For hundreds of years after the two planets co-existed with all the other inhabited planets, that were populated by planetary governments. However as Mars started to surpass Earth, tensions soon reached a breaking point at the infamous Calipso Skirmish, and war being declared by both sides, sparking the Systems War.

Interplanetary war wasn't glorious, it was slow and tedious, ships would take months to reach between the two planets and they may not even make it in time due to Mars rotation around the sun. The war dragged on for decades onwards, with skirmishes and battles across the Solar system and two climatic battles. The battle above Earth, and the battle of Olympus Mons. The war was a slow, strategic, nerve-wracking contest, that caused unimaginable destruction, and billions of lives lost in war. Humans almost went extinct cause of this war and it took a long time to recover from the destruction, both planetarily and population wise. The survivors of Earth and Mars, for the common interest of mankind made a plan to ensure that humanity would never fight amongst themselves ever again. Humanity made massive reforms to their politics, and economics, and they changed themselves. They genetically modified humanity into a new subspecies, that was made smarter and adapted to expand better across the Stars.

This caused a split amongst the humans that were outside of the Solar System (everyone else), and the majority of the other planets seceded from Humanity's empire, which led to more chaos and the complete fracturing of the empire as other planets took advantage of the situation to form their own empires. Other than this, the plan to unite the two worked, and the new generations of humanity lived peacefully on the worlds they inhabited.

## Society

**(Pre System War):** Humanity on Earth was divided into several countries, some of which encompassed entire continents. While others such as the capital of the planet, being its own country and being essentially a capital state. These countries operated pretty much the same as in our world, except there were rules prohibiting war and conflict, as well as competition.
