Think about it. The Citadel explodes in low earth orbit. What's gonna happen to Earth?

The mass of the Citadel is approximately 7.11 billion metric tons. Info gotten from masseffect.wikia.com/wiki/Citadel

The Citadel has 5 arms, each arm weighs in at a little less than 1.422 billion metric tons. (need to assume a little mass is lost because of the inner ring)

A quick search on google pulls up nssdc.gsfc.nasa.gov/planetary/factsheet/asteroidfact.html

A little math shows that each arm would roughly equal a mile wide asteroid.

Asteroid          Diameter (km)      ~Mass 10^15 kg
Icarus                   1.4                              0.001             =       1 Billion Metric Tons
Apollo                   1.6                              0.002             =       2 Billion Metric Tons


So now that the citadel has exploded, you have roughly the equivalent of 5 mile wide asteroids in low earth orbit. Eventually they will decay, some faster than others. The arms pointing down at earth could decay very rapidly.

5 mile-wide asteroids slamming into the earth from low earth orbit may or may not be an extinction level event, but it's certainly not going to be a picnic either. Especially with Earth's infrastructure already in ruins.

So basically, the Earth is doomed.

its also made of super reaper armor, so im asumeing its harder than a atreroid.

so earth is super doomed lol

Well, the relays blow up like supernovas according to the Arrival DLC, so I'm guessing it doesn't really matter for more than the 10 minutes or so it takes the shockwave of the Charon Relay exploding to wipe out the entire system.

I was wondering about that myself.

You make an excellent point, but if for the sake of argument the relays simply broke apart and did not go boom, Earth's still doomed.

[Nightshade386]

I'm just saying, you could theoretically "sci-fi" your way out of anything. But if you wanna get all scientific about it....there it is. Shepard destroys everything he's ever cared about no matter which ending you choose.

Depends on where the explosion happened. If the explosion pushed the pieces away from the planet with sufficient force for it to escape orbit, then Earth is fine. If not then if the explosion breaks down the pieces to very small ones, then Earth is again fine as they will burn up in the atomosphere. If any piece is too large, then yes its possibly an extinction level event.

BUT, remember that Mass Effect's technology level is remarkably high and includes terraforming tech. As the extinction will be due to dust clouds rather than straight forward being blown away (other than those at the impact site), it is possible that with sufficient resources and build time, to remove the dust clouds.

[Nobrandminda]

This is just one of the many, many problems with the vagueness of the ending. Smart asses like to bring up the Endor Holocaust in Return of the Jedi, but really, we know that didn't happen because after the death star blows up, we return to Endor, and it's fine.

Here that doesn't happen. Unless that planet Joker landed on happens to be earth, the last time you see it is when the Citadel explodes (killing everyone aboard unless they were dead already when the reapers took it to earth. There's a cheerful thought for you). So there is absolutely no reason to assume anything good came of it.

[fluffyburrito]

I still don't understand the destroy ending in terms of assets. If you have really low assets, earth is destroyed completely in the blast. Really high assets? It... MAGICALLY... survives completely intact. It boggles the mind.

[Craven1138]

Most of galaxy is doomed. Without mass relays food supply, resources supply is cut of, families are torn apart, fleets are trapped in Sol, Krogan don't have their leader...

Maybe middle ending is least cruel - swift death to everyone.

[Gunzwei]

The marketing team had a typo. It's not take Earth back. It's take Earth with you.

I'm going to have to disagree with you on your points.

Any explosion powerful enough to force any piece of the citadel to escape velocity would push the pieces facing in the opposite direction towards earth with that much greater force. So now instead of 5 one mile wide asteroids in decaying orbits, you have 1, 2 or maybe even 3 one mile wide asteroids hurtled towards earth going at least 7 miles per second (~25,000 mph). That force make the situation worse, not better!

It is extremely unlikely the citadel wards would break up into small enough piece to burn up without hitting the ground at all. In fact, a major breakup of the arms would be worse. The Earth gets hit with a shotgun blast instead of a bullet.

Earth's infrastructure is in ruins following the Reaper invasion. It would be nearly impossible for Earth to be terraformed back to life, especially without any kind of help outside the system (the relays are gone).

Wow, I remember reading about that years ago, and completely forgot about it!

I think Endor's gonna be in worse shape than Earth though, given the difference in mass between the two stations.

[lucidfox]

Wait, what?

With low assets, Earth is destroyed?

Did I read that right? Destroyed? As in, blown to chunks? Alderaan'd?

What the flying rat heck this makes even less sense than the actual "ending" seriouslywhattheheckaaaarghmypoorfeeblebrain

[SilentCO1]

I chose to Control the Reapers, so I made them all suicide into the other planets to even out the destruction. Especially the Salarians since they didn't help me. So for me, everything blew up, atleast in my head they did.

In the worst ending the energy released from the Citadel sterilzes the surface of the earth. So no not Alderan'd, just all life in the planet's surface is incinerated. Not much better I know.

Not that it matters, given the falling pieces of the Citadel eventually crashing into the Earth.

Actually the increase of force only affects the impact crater and the immediate casulties. As already explained, extinction happens only due to the dust clouds preventing sunlight from reaching the planet surface. This doomsday scenerio is likely detailed in whichever source you check for the size vs impact crater. Notice that no one talks about how the Earth dies due to impact damage because everything that is not a moon, planet or star is small fry compared to the size of the earth

I reviewed the ending video again. The explosion happens in the center which pushes the arms away. Then notice the angle the citadel is at. It is possible that the arms are pushed away though without seeing the full force and direction exerted after the arms seperate, it is difficult to say

It is extremely unlikely the citadel wards would break up into small enough piece to burn up without hitting the ground at all. In fact, a major breakup of the arms would be worse. The Earth gets hit with a shotgun blast instead of a bullet.

I did not state likelihood or probablity as that is unknown, only that its is possible. If there are secondary explosions, this likelihood increases but the video is too short to see if they happen

Earth does not need to be terraformed for life. Earth has not changed in the ME world nor has it become unhabitable (other than the ending that destroyed earth). You merely require the ability to absorb or funnel soil and dust particles.
 
You also forgot several things. There is a combined fleet of X number of alien races, there are vast amounts of Reaper tech now on the planet and finally Intact appliances, metals and other needs are all still on Earth either buried under rubble or abandoned.

[Chromako]

Boom! Regardless of the Citadel, the Charon Mass Relay is destroyed. Remember what happened to the Batarians?

No more earth. I'm not talking about melted slag. I'm talking about fragmentation. 

Since the Citadel is the most powerful Mass Relay, it might take out all the nearby star systems, too. ouch.

[Hizuka]

Let's face it - Arrival pointed out that the destruction of a relay releases an energy blast that is on par with a supernova. As Chromako pointed out, the Citadel is the most powerful relay of them all, and is a SECOND relay in the Sol system.

So whichever ending you picked, you blew up the mass relays, each of which would have taken out the system it's in. That means that all of the major races got to deal with their homeworlds being incinerated. This also means that the krogan (who left their females on Tuchanka) are certainly going to go extinct, as will, most likely, the quarians, assuming the geth didn't already exterminate them in your game.

Just to add to the horror, supernovas are no joke, and they can incinerate neighboring star systems when the energy (and the gamma rays) reach them - look it up if you don't believe me. So, Bioware really screwed the pooch on this one - between the immediate blast effects and the results in a few years from the expanding wave front, all life in the galaxy is likely to be extinguished, possibly for good.

Good going, Shepard.

Yeah, you can't really think about any aspect of the ME fiction for too long. Do what I do and focus on the characters and move along.

Sure, the Quarrians are said to have "weak" immune systems, even though the explanation for this actually describes a hyperactive immune system. But Tali's cute, so whatevs.

Well, unfortunately, I don't think you can just break apart the mass relays and have the mass effect cores that power them do nothing. I see it as like popping a balloon full of air. All that energy has to go somewhere somehow.

Imho, I don't see how earth (or the galaxy for that matter) could resonably survive the mass relay's mass destruction. I'd love to hear an explaination tho. Maybe I'm just missing something. Maybe eezo cores don't require containment and are just a hunk of metal that would harmlessly float in space. I doubt it, but maybe.

My post takes the assumption take the relays don't go supernova. Otherwise what is the point of my posting it to begin with?

For record, when I first watched the ending video. I just assumed that the relays went supernova and ruined the galaxy, and the Normandy hadn't gone through a relay, but was running from the explosion via regular FTL. The video of Shepard I just assumed was him take his last gasp of air before expiring.

My first impression of the ending was "well, everyone's dead, and the normandy crew will simply take longer to die than most of the galaxy". A truly depressing scenario.

Enough about what I thought of the games ending though. The object of this thread was a "what if" scenario. What if the relays didn't go supernova, what effect would the Citadel's destruction have on Earth?

An aversion of 
http://tvtropes.org/...oEndorHolocaust .

Basically, it would have the effect of multiple astroid strikes, each equal or greater in mass to the one that created the Chicxulub crater and caused the K-T extinction.  ONE caused thousand foot tall tidal waves, atmosphere catching fire. and 'nuclear' winter, and we can expect several of them to hit.  Then there are all the poisonous compounds used in the construction and maintenance of the Citadel.

Basically, planetary extinction.  Hope the Quarians a) weren't exterminated in your game, and brought their liveships for some reason.
