We don't know how close the citadel is to earth. We KNOW it's not in the atmosphere.
It looks to be well out of orbit. Far enough away anything that objects would likely orbit it rather than crash to earth unless on a direct trajectory.[/quote][quote]And later, Funkdrspot wrote...
I guess I could draw a diagram if you guys want but this isn't NASA stuff, this is simple applied physics. NASA stuff is finding the weight of an astronaut 4km from earth's surface.
Most people think that when you leave orbit that you leave earth's gravitational pull. Or that weight = mass.[/quote]
Maybe you just think people are dumber than you. Objects in orbit (far enough, not on Lagrange point) will eventually fall down if still under Earth's gravitational pull, it's a matter of time. You didn't know that?

The shockwave from the blast must have just shaked the structure, dislocating the arms. The arms were not "pushed" by pressure (in the void?) from the explosion.[/quote]A shockwave is pressure. 0/10 on your physics test. [/quote]
Maybe you should take a reading class.

Everybody can read. This explosion happens between the crucible and the platform, and expanses radially from there, for the most part. Its growing speed is not stopped by air,[/quote]LoL just stop dood.
A. An explosion is CAUSED by a mix of fuel and air.
B. There is no atmosphere in outer space.
C. If anything, an explosion in outer space will be SMALLER due to A and B. [/quote]
Maybe you cannot understand what you see, even if you try to describe it : this explosion on the Citadel is of the "fuel burning" type, yet that happens in space, no atmosphere. Would you care to describe the visual aspect of an explosion in space?

and if it did not eject the crucible, it surely did not push the arms away. [/quote]Rofl. As you said, the blast came from the center and expanded radially. That blast itself will push those arms away from eachother, radially. What does an explosion do but push you back?!
For the rest, just reference Newton's 3rd law of motion[/quote]
No need for Newton, just watch the cutscene : the explosion occurs between the Citadel and the Crucible. If this explosion can dislocate the arms 3 km away, how come it doesn't push the crucible towards Earth? Maybe you jump to conclusions a bit too fast?

Shockwave through the structure is more probably the cause of the arms' dislocation than the tiny pressure at the end of the fireball growth.
http://www.wwheaton..../mad/mad12.html[/quote]A shockwave is energy. It is force. It eminates from the center of the blast. It is literally force being applied to push the citadel arms away from the center.
Seriously dood, stop talking physics. It's embarrassing. Go take a class and come back.[/quote]
Again : why did the crucible remain in place? You even supposed that since the "hinges" connecting the arms to the hub seemed frail, they would have snapped out before the big arms break apart, but you do not apply that to the Presidium arm reaching the center of the hub, or the crucible just besides the explosion. Maybe you need glasses? No need to feel embarrassed.

Explain the nature of this explosion, if you can. Maybe the NASA could use your knowledge.[/quote]Think of the Citadel like a big flower. If i put a firecracker in the middle of it, the force from the explosion will be a straight vector that will push them away from the center of the flower.[/quote]
As I said, you don't seem to know a lot about explosions in space. If the "fuel+air" (lol) fireball stops its expansion (quite visual, in fact) abruptly (for no apparent reason -no more fuel to burn? The air stopped it?) just before hitting the arms, I doubt you could conclude that this type of pressure, being stopped by a vacuum (lol), could push 45 km of solid construct, if it didn't even push the crucible. Maybe you thought this was a hollywood movie?
