During the Mass Effect 4 “presentation”, they said that you’d be exploring totally uncharted space because players wanted to go somewhere new.. And, while not 100% completely explored, the Milky Way galaxy was pretty much tapped out. The galaxy was neatly carved up into different zones of influence based on species or political affiliation (or lack thereof).
If they’re talking about 100% new space, I have an oddball theory. Months ago it was said (confirmed?) that the next ME is a sequel. naturally this made me laugh because that would mean they’d have to canonize an ending.
With that in mind, what if they canonized control, or, god forbid, synthesis? Because with the technology of the Reapers at the disposal, that would make travel to new galaxies entirely feasible. Look:
This is how far away the Reapers were from Earth Alliance Space at the end of ME2. I use Alliance space as a reference since it would appear their territory was attacked first, with the batarian homeworld (which is actually in Alliance Space according to the wiki) being practically wiped out in ME3.
Using the above as a reference, I tried to recreate the distance in a “game” called SpaceEngine, basing the distance mainly on the size of the galactic core. The crosshairs below are centered on Earth.
Plus or minus some parsecs, I guess. Apologies for the images, tumblr resizes them weirdly.
Anyway, that was their distance to Earth at the end of ME2. Six months later, in ME3, they arrive. They went almost 4000 parsecs in 6 months. 4000 parsecs is 7.66940463 × 1016 miles. That is 76,694,046,300,000,000 miles. In six months.
That is 12,782,341,000,000,000 miles per month.
That is 426,078,030,000,000 miles per day.
That is 17,753,251,000,000 miles per hour.
The closest galaxy to the Milky Way is the Canis Major dwarf galaxy, some 25,000 light years, or 146,742,840,000,000,000 miles from Earth. It would take just about 11.5 months to reach Canis Major.
Beyond that, the closest spiral galaxy is the Andromeda Galaxy, and it is a hefty 1.469625 × 1019 miles away, give or take a bit according to google calculator (I hope you didn’t think I was doing this on my own). To reach the Andromeda Galaxy using Reaper Speed®, it would take just 95 years, roughly. More than doable for an Asari or Krogan, and easily done in just two generations by humans, since the first generation on a colony ship would be well past their prime but not yet dead.
What if Mass Effect 4 takes place during the exploratory boom in a brand new galaxy after the Reaper War ends in anything other than Destroy?
