I was curious how a planet like Coruscant from the movie Star Wars would work in real life, hundreads of different sapient alien species inhabiting one planet. Let's assume now they all come from planets like Earth with an atmosphere consisting mostly of nitrogen and oxygen with traces of water, carbon dioxide. The gravity of their homeworlds they originate from does vary between 38% of Earth's gravity to 180%. Would the aliens to be able to eat the same food grown on the planet? Would it be possible for the aliens to live peacefully? What type of government could this planet have to maintain peace? We can refer to the planet as "Elysium"
