Saw some discussion on Humanity’s meteoric expansion and advancement after discovering Mass Effect technology and whether it was believable or not because it happens too quickly. So I thought I would give my own analysis on the topic.
(TL:DR Humans are sufficiently advanced and overpopulated enough to rapidly expand with the discovery of Mass Effect technology, plus a splash of space imperialism)
Humans discover Mass Effect physics on Mars in 2148. About a year later, the Charon Relay is discovered, leading to a rapid expansion period over the next decade. In 2152, Humanity founds its first extra-solar colonies, including Demeter, Eden Prime, and Terra Nova.
By 2157, Humanity has expanded beyond the Exodus cluster and comes in contact with a Turian military vessel, sparking the First Contact War. At this point, Humanity has established a significant presence within the region of space that will become known as Systems Alliance Space. The colonies are depicted as being highly urbanized, featuring permanent development beyond prefab habitats. This is likely a result of rapid adoption of Mass Effect technology, which may have been easier to translate into construction applications than deepspace starships and space stations, which were advancements heavily informed by data found at the Mars Prothean site. So it’s reasonable to think that urban development and construction (already 125+ years more advanced than our own) would be accelerated by the discovery of Element Zero and Mass Effect fields. This would make massive colony developments within a decade seem more feasible, if only by virtue of how Mass Effect technology works in the ME universe.
Humans must be rapidly advancing on their own by applying Mass Effect technology to already existing tech and machinery. Then consider that Humans have made contact with some of the most advanced alien civilizations in the known galaxy, the Salarians, Asari, and Turians. With access to galactic trade with other advanced alien civilizations, Humans can rapidly adapt and evolve their technologies to match that of their alien neighbors. This kind of rapid advancement can be seen in our own history today, having discovered flight technology and then landing on the moon just 70 years later. Mankind is capable of massive leaps in technology in a short period, especially when we can reference technology that has already been invented, such as weapons tech observed and adapted by opposing factions during war. Mankin’s technological growth seems feasible, if a bit drastic.
Over the next decade, Humans continue to expand and are given an embassy on the Citadel in 2165 in recognition of their growing power and influence. It has been 17 years since the discovery of Mass Effect physics. By now, Humans have expanded and colonized dozens of worlds and systems. With a massively overpopulated homeworld, estimated to have a population of 11.5 billion by 2183, it seems reasonable that there would be plenty of people able and willing to leave for the colonies to seed populations numbering in the tens and hundreds of thousands on other worlds by 2165. We don’t have clear numbers of how many humans live beyond the Sol system, but its largest colonies have populations numbering in the low millions (>5 mil.). Many more colonies have populations in the hundreds of thousands. It seems feasible that a colonial exodus of a billion humans to the colonies could be done over 20 years, provided Human manufacturing and resource development could keep up to produce construction materials and starships to facilitate that level of deep space travel and interstellar colonization. Considering the potential for accelerated construction rates in the year 2165, having over 15 years to adapt Mass Effect technology, this kind of boom in infrastructure could be possible.
All this together makes Mankind’s explosive expansion seem plausible, at least within the Mass Effect universe. Given the armed conflict of the First Contact War with the Turians and ongoing conflict with the Batarians in our backyard as well as pirate threats in the Traverse and Terminus Systems, humans also have the classic motivator of military aggression to power expansion. Either to match political and military threats like the Turians or to muscle out pirates and slavers with force, humans have often expanded in the face of such threats, treating them like challenges. Imperialism has long been a human mentality and the Systems Alliance continues this on an interstellar scale.
Humans are essentially an amalgamation of traits found among the other species, namely the council races. Capable of technological advancement of each and as militarily capable as the Turians, and are even adept at trade and diplomacy. Humans are like softer Krogan but more advanced. It’s no wonder so many aliens are afraid of or despise humans, they arrived and expanded to a position of insane amounts of influence within the blink of an eye to some races and a single life time for others.
So, in conclusion, Mankind’s expansion to an interstellar empire over three decades may seem impossibly fast but a combination of overpopulation spreading into newly available space, an already advanced civilization gaining access to vastly more powerful technology, and an imperialist and expansionist mentality makes it possible. Humans are insane and that probably won’t change in 150 years lol
