Moot's Final Solution to the Australian Question
Realistically this would have just ended life on earth shortly after touching the atmosphere
>>23704716Nah. We've been hit by bigger and faster things.
>>23704716Some people have done the math, making assumption for the materials the colony's made out of, but apparently the crater this thing makes in Australia is unrealistically huge since most of the colony would burn up or fragment in atmosphere. Not like these things have any thermal protection for atmospheric re-entry. The one from 0083 though, that one should have been enough to cause worldwide famine.
>>23704721I mean the asteroid that killed the dinosaurs was only 6 miles in diameter. Space colonies are much bigger than that so I figured it'd be pretty apocalyptic. Unless it's density is the bigger factor here? Either way it would flash vaporize a part of the ocean just by coming into contact with the air, wouldn't it?
In the spirit of fairness, the Earth gets to lob 1 satellite body of equal size at Munzo.
>>23704728Yeah. I'm one of them. The crater's nonsensically huge. Rest of the numbers roughly work with estimates on the actual O'Neill cylinder values. Never did any for 0083's impact so I won't speak to that.>>23704733They're bigger (mostly just longer), but they're effectively empty. With these kinds of scales you mostly care about total mass, velocity, and a bit about the shape to tell you how much energy gets shoved into the atmosphere rather than the ground. Density dictates the physics of the crater itself (how deep it gets and what the shock stresses look like, etc.) but in the broad sense doesn't matter that much outside extreme cases. All that said, the Vredefort and Sudbury impacts were bigger and probably substantially faster (Vredefort was probably ~2x faster which means 4x the energy for the same mass and it had more of that) and while those were a big deal they were a long way from "obliterate the entire biosphere" scales. All of these, including Operation British, are going to be pretty devastating, but there's quite a lot of planet to absorb that devastation.
>>23704728>>23704776One of explanations I've heard is that it's not just the kinetic force it's that it had a giant reactor detonated on impact.
Aren't colonies hollow and like 50% glass? Not to mention they aren't designed for atmospheric drag so they'll just break down into a cloud of smaller and smaller debris until they burn up Wouldn't we get a field of comparatively smaller craters over a large area instead of just one big crater?>>23704850Reactors don't explode like nukes, and minovsky reactors are all about magnetic fields so there's nothing to explode. I guess the Helium-3 fuel? But even assuming the stores were full and none if it leaked out prior to hitting the ground it would still not be enough to delete australia like that
>>23704859Anon a Minovsky reactor explosion in episode 1 of the series is strong enough to blow a massive hole inside of Side 7. Minovsky reactors in universe are essentially micronukes. Now imagine a big fuck off reactor or a series of smaller reactors all going off at once.
>>23704881Aren't minovsky reactors only supposed to go nuclear if hit with beam weapons? And doesn't that Zaku explode specifically because the Gundam killed it with beam sword/saber? And that's also the reason whh beam weapons are restricted in colonies, and a significant plot point in 8th MS
>>2370490708th also has the Federation forces freaking out about the possibility of a reactor explosion when some MS (ground-type GM from memory) gets caught in a non-beam tunnel explosion. Honestly, how the shows portray reactor explosions is kind of all over the place. Zeta barely gives a shit; Victory makes them mostly a big deal; Unicorn does both somehow.>>23704881The big fuck off reactor theory isn't unreasonable (though I don't think the scale would contribute meaningfully to an impact event even then), but I've never seen it supported by anything. Come to think of it, I can't recall anything talking about reactors on colonies at all. Closest was the nuclear propulsion they have.
>>23704721>>23704728>>23704776There is a world of difference for a object that is only 1/3 the size of the 32Km O'Niell 3, which when its largest chunk hit (funny how Tomino et al forgot the other chunks) was smaller than the solid iron rock that slammed into the Gulf area. Funny also that was the smallest of the three major impactors since the Haden Era.
>>23704965I mean 60 Gt I no laughing matter...
>>23704969But its a fucking joke to the Dino killers 126Tt...
>>23704972The Second Dieoffs 148Tt
>>23704977And the one that nearly ended all life that became the Verherdofort (the largest crater on Earth) that occurred 2.4 billion years ago.The impacts that happened in the Haden Era were probably far larger, but the Earth was putting itself together at that point so, really could not be mesured. Gunnms jab at what caused the fall of their Earth was always a funny shout out.
