Of all the wierd things Bioware was trying to say in the ending i thought this was the easiest to understand, bt people seem to be reading it very wrong. That's not to say other bits of it done have problems but it makes sense. . . . to a degree.

Joker traveled through the Charon Relay (dont ask me why the hell he is fleeing the battle for all life considering this guy took down Soverign without sweating) but when the energy of whatever colour you choose hits the relay, the relay shoots it the to next one and explosed or goes off line.

The relays were never really instantanious. In ME they didnt hit Eden Prime in a second, they had to travel for a few mins after hitting the relay.

And while the energy was shown to be harmless to other ships, the concentrated mass of energy or the collapsing mass relay corridor damaged the Normandy and sent it flying into a uncharted part of space.

Of course the one must admire the odds of them landing on a planet capable of supporting life at all or their being one in the area. Even more if Joker couldnt control the ships anding at the time.
