To orbital nukes, actually you should look up how ICBMs work. Most folks think we just fire them straight across and no, we don't. Not only that, but like you just pointed out, it would be pretty easy to rig up weaponized stuff to shoot into orbit if we didn't have it already. We've been to the moon already, I don't see why we can't just launch a rocket with a bomb.thaluikhain said:In atmosphere, yes, in vacuum, not so much. I'm led to believe that we don't have missiles designed to reach orbital targets that are designed to carry nuclear warheads, as there is currently no use for them, but possibly some could be modified for that role.
On the other hand, though orbit capable weapons aren't that common, they can be launched from surface vessels, submarines, planes or large trucks more or less anywhere on the planet. The target is sitting there in orbit with nothing to hide behind.
On the other other hand, the technology to travel interstellar distances, they might be able to intercept and destroy missiles at extreme distances, and definitely won't need to be in orbit to attack.
Kinetic bombardment doesn't have that issue.Torkuda said:Well one would assume that blasting the sh** out of us with an alien version of nukes would actually be incredibly stupid if they wanted our land. Unless they live in radiation, and even then the results of their attack would probably be pretty unpredictable even for them. War is almost never that straight forward.
Now, certainly, there may well be issues that prevent that, which a writer could use, but it's very annoying when they don't bother.
Also, as a race we've always been capable of traveling great distances, but that has nothing to do with the range of our weapons. Just because aliens can travel over light-years, doesn't mean they have missiles that can be fired from light years away from a target. I guess that would finish us off... well... actually we could just shoot the missiles down... and also if they started firing at a hundred light years out right now, I'm not sure if that would work several centuries from now, after all, the missiles could only travel so fast and by the time they got here, it would be at least 100 years later.
I even had one person ask, "hey, what if they shot down every missile one hundred feet after it left the silo?". My response was something along the lines of "we could only hope they would be that stupid". Then we could just launch five hundred missiles, only twenty of which are actually a threat, and watch these little micro managers try to figure out which ones to shoot. He even countered with "what if they knew how our nukes read on radar could read all the missile trajectories?". Response, "And we're back to aliens are gods". How exactly would they know all of that, they're aliens. Sure they might have done SOME research, but the settlers probably did SOME research on the natives when they landed, but that precise of intel is pretty impractical.
