Intergalactic Mass Relays

... isn't that the long-term goal of the andromeda initiative?

Maybe Nexus is a mass relay disguised like Citadel in MW.

Ok, lets forget all the mass effect lore that says the milky way didn't nearly have the technology to build mass relays.
The protheons were far more advanced and they only were able to build a micro relay to get onto the citadel in ME1.

It might be possible they dismantled a relay to put it back together but would you really have an expensive intiative that relies on the crux of you putting together a machine and you have no idea how it functions if something goes wrong? Seems pretty silly to me.

The entire intiative seems silly to me because who would fund an intitative and see no return on their investment? Unless these same people were going on the intiative or it was being funded at the highest levels because someone believed in the reaper threat.

If thats the case, this whole thing about being reconnected with the milky way is a lie. Why go back to a galaxy and alert the reapers to your existance which could jeopardize their invasion?

All great human discovery had a purpose beforehand, 

Christopher Columbus was trying to establish a faster trade route to india for portugal
The americans landed on the moon to emphasize their supremecy in the cold war. 

I don't see yet what the andromeda intiatives return is supposed to be. 

Nobody just goes for the sake of exploration. Thats bad for business.

Another theory:what if we find a remnant intergalactic mass relay that connects with MW.I really what a connection with the MW.

Not relays no. Nobody has the knowledge in how to make them. I mean in the 600 years since we left maybe the Milky Way will have figured it out but not the people in Andromida.

If a relay is built or brought along, then what happened in the Milky Way will have to be dealt with.

Does Bioware really want to open that can of worms?

Hey, it worked for the Crucible!

A popular theory on BSN is that the Nexus is actually a Mass Relay with the four arks being its external batteries. One of the main goals of the Andromeda Initiative is to create a link between Andromeda and the Milky Way, so an intergalactic Mass Relay is essential to those plans.

It would make sense.

It's more likely that the Nexus is a Mass Relay in disguise, with what being the Citadel 2.0.

You mean like how most people have forgotten all the mass effect lore that says the Milky Way didn't have the technology to build intergalactic spaceships?

There's just that one on Ilos that connects to the one on the Citadel, both built by the Protheans. Neither of which were destroyed in ME1. The council even confirms that they sent people to Ilos and that Vigil wasn't active anymore. It could have taken them two years to reverse engineer the Prothean tech for the Andromeda Initiative.

For explorers or colonist, top priority for many reasons is to keep or restore a link with home world. It is natural (except for outlaws or similar). So, yes, working on a galactic relay, will be a natural top priority project.
