Why in the prologue people are astonished by "floating rocks"? Why do they point it out?

the synthesis ending deserves the hate it get but not this type of hate. Everyone of the endings is told in the light of the Victor based on the choice made. Not even Shepard is exactly the same if you choose the control ending. Edi is just seeking as a being that 2as changed by that ending choice, it does not mean the only way for peace was to choose synthesis. It just means it was the only choice with no furture problems preceived by her in the state of galexy in synthesis. Don’t take what is said as literal.
Remember this is an ending where you let a being win who thinks think the best solution forthe galexy is to turn everything to tools it can control. We are just seeing an ending in the perspective of a being that is hopped up on the catalysis indoctrination.

This was my first wtf moment of way too many in this game.  By the time the Hyperion hits the scourge, countless bridge crew, engineers, and med staff had woken up, then Ryder has woken up, be examined, had time to drink a cup of coffee, and THEN they hit it.   It seems like a MINIMUM of 30-45 min must have passed, plenty of time to see and avoid the scourge.

It has been said that "they explain it moves in the book", but it never says that in the game.   We fly through it to escape the kett like its not going to move and get us, we are able to plot a course through it, in the final battle we even snuggle up against it without worrying it will move and get us.  They never say, "Holy Crap, it moved!", they never warn you about getting  too close because it might move....everything in the game makes it seem pretty immobile.

Maybe " in the book" they explain a lot of things that dont make sense in the game, but forr those of us who didnt read the book, we are left with a lot of inconsistencies.  And this is only the first.....

I thought it had something to do with whatever electromagnetic phenomena was occurring. If you notice before Cora defends that red head woman from a lightenting strike, the rocks in that area began to float upward. I just figured the rocks were made of metal.

The way I see it, the Hyperion came out of FTL close to Habitat 7, which is full of remnant tech, which the scourge is attracted to.

So it is possible that while the scourge does not move much in deep space, it moves here because of the proximity to the planet and the remtech. Therefore, it could have moved to the vicinity of the ship.

Also, it being a an unknown phenomenon, the sensors might not have picked it up before they were calibrated (where is Garrus when you need him), so they could only see it out the window, not with instruments. Add to that that the ARKs might not have been designed for rapid maneuvers (unlike the Tempest) and we hit it.

Sure, it requires a lot of head canon and good will but what in this game doesn't.

As for the floating rocks, sure, it's possible to make rocks float in the ME universe but they don't float on their own and I guess you'd probably need a massive ME field generator to make all those huge rocks float, so that was indeed weird to see.

That part always kind of bothered me. If I play as a biotic she acts like she's the only one with her snide reply to Liam.

Liam just watched me use my biotic powers without comment, Cora says she's known me for sometime, so saying to Liam it's not contagious is just odd imo. The game most likely sees you as Security and never points out your other abilities. 

That's what I mean. I use my biotics in front of him and he never reacts, but he reacts to Cora and she acts like she's the only biotic. I had hoped our own abilities would be acknowledged.

As I recall the Scourge is dark energy. Their scanners wouldn't pick it up unless they were specifically on the look out for it.

lol

I wish I could say the same thing about Sam constantly stating my life support levels are fine.

Tells me when it's in danger but god damn I don't need to be reminded that they're fine.
