So what are we to assume, without the mass relays is there no way to travel the universe? I selected the 'control' ending, which, as far as I can remember, didn't disable or destroy any ships (or did it?), other than the mass relays and the Normandy (which is in a slip stream/whatever at the time when the relays were being destroyed?). Hell, even the citadel is still there just closed up (what does that mean?).
With that control/blue ending, can't we assume life continues on, just without the relays, and Shepard (at least in human form)? And again, what does that mean? Can the Turians and other races still make it back home, just not as quickly, or are they simply lost without the relays? Is there no space map, or is the distance simply too great to travel? And how great? Like impossible?
Also, the races built that crucible pretty quick, can't they use the same kind of tech to build more relays or does it fall back to not being able to traverse the galaxy without them, therefor not being able to rebuild new ones?
I'm lost and perhaps some of it is ignorance on my end, lore wise. But I just feel like the ending left me with a ton of unanswered questions.
