If we're assuming that they think in a relatively similar way to us, then no, there really isn't a lot of reasons for them to invade in an ideal universe. Basically any resource you can think of could be found in near-infinite supply around the various stars of our galaxy, and I like to think that the *really* bad species just wind up nuking themselves into oblivion shortly after learning to split the atom (we sure almost did). Short of them just being assholes, or having some sort of religious reason behind it, I don't really see reasonable aliens finding the need to hurt us. It's entirely possible that they could be indifferent to us, but indifference doesn't mean malevolence.KyuubiNoKitsune-Hime said:This is something that comes to mind to me from time to time. If extraterrestrials discover the Earth, do you think that they'll invade the planet?
Personally I'm rather optimistic on the subject, being of the mind that any species that can make interstellar travel won't really have an intention, or a reason to invade the planet. Partly because there's a chance that they won't been keen on the idea of disrupting a species that's barely space faring. There is also the thought that they'll be advanced enough that they won't need to invade the planet. If they need resources it'd be easier for them to take the materials from asteroids and other planets, probably avoiding human attention entirely. Even a species that travels long distances at speeds slower than light will more than likely have the ability to support themselves, with out need to exploit Earth.
So that brings up the question of first contact, will they come to invade us? I personally think that if an advanced species ever makes contact with us, before we get to any sort of interstellar travel, it'll be for different reasons. For instance humans as we are might be more creative at figuring out uses for technology, so first contact could come because they want us to develop new applications for their technology. It's also possible that some of the things that we've invented are things they haven't, leading them to want to trade technology.
Still we might be the only advanced civilization in our galactic neighborhood, if not the entire galaxy, so it's possible we'll go visit other civilizations before they can reach us. It's also possible we might be the only intelligent life in our area, or galaxy, in which case we'd have pretty much free reign.
So Escapists, what do you think?
U-235 (ie the stuff you'd make a weapon from) has a half life of 700 million years. Pu-241 is 24,000 years. Neither is likely to decay any time soon, but taken on an interstellar scale...Strazdas said:Depends on material used. for example Uranium that was used in Chernobyl nuclear plan has a half-life 3.5 billion years. Though yes, pretty much 99.9% of current nuclear weapons would degrade before reaching the target. But one should never forget a dirty bomb.
This is, unfortunately, a load of rubbish. If you asked someone in the middle ages, they might well tell you that by the time we learned to fly, walk on the moon, hold conversations with people on the other side of the planet, build computers and robots etc that we would have learned to stop killing each other. This hasn't happened, and there's no reason to think we won't get to space travel and still be killing each other.Seraj33 said:My thought about this has always been that if aliens were ever to reach the technological and social level to be able to space travel, they would have to have ascended all the negative sides to humanity. They must have learned not to war and therefor reached world peace. They must have learned to maintain their own planet and resources. If they are warring and throwing their own planet into the garbage bin like we are doing, they will never EVER have reached the point of intergalactic space travel.
We've got better toys than we did back in the Middle Ages. If we don't stop killing each other, we'll never reach interstellar travel. You can only play with matches so many times before you get burned, and the way we're headed, even stateless terrorists will have access to a lot more than just matches.Bad Jim said:This is, unfortunately, a load of rubbish.

An individual might get mauled by bears, that doesn't really motivate us to go purge the bears from the Earth, at least not anymore. Any extraterrestrial species is going to know this planet is inhabited before they establish a parking orbit, that means they'll be aware of us before we are of them. This easily translates to an idea of any weapon we have, is probably something that's far to primitive for them to consider a real threat.thaluikhain said:Define "threat", though. People get mauled by bears.
The problem is that long term exposure to deep space would cause any atomic bomb's mechanical detonation method to fail. So the weapon wouldn't survive the trip. There's also no guarantee we could hit an extra-stellar planet anyways because we're just now learning how to spot planets around other stars, we spot where they were in the distant past. We can't even be sure at that point any planets we spot are in the same orbit as they originally were. Again in deep trans-stellar space we'd also have to compensate for the gravity of all near by stars, which isn't something we can quiet do yet.Strazdas said:Depends on material used. for example Uranium that was used in Chernobyl nuclear plan has a half-life 3.5 billion years.

We consider cockroaches and ants to be pests, not actual threats, there's a difference. We only really exterminate such things when they're somewhere we don't want them and it's impossible to eliminate something that's measured in metric tons per acre, because to do so we'd have to seriously damage the environment.Strazdas said:you dont have to be on same technological level to be a threat. cocroaches can be stamped on easily, but we still consider them a threat when we find one. they may not be able to destroy humans, but they are still a nuisance. as a result, we have invented and used variuos ways of killing them and we keep devising more and more efficient ways to do it. somone else made an allusion to aliens seeing us as "ants". we have killed forests ants so much that they are not considered endangered species. i wouldnt want to be an ant in a human world.
Not entirely, any aliens could be dogmatic about something, or want to take control of us because they see value in us, but countered by the possibility that we could kill our selves off. So there might be extraterrestrials that would invade and rules with the idea of it being for our own good.IOwnTheSpire said:One of the poll options is weird; invading our planet to save/better us seems contradictory.
These are mere technical constraints with technical solutions, like having an onboard factory that mixed the chemical explosive on approach, or better AI that can analyse planets as it gets to them and head towards the one with the Klingons on it.KyuubiNoKitsune-Hime said:The problem is that long term exposure to deep space would cause any atomic bomb's mechanical detonation method to fail.

I think that Calvin and Hobbes quote is probably the closest to true. Not that we're likely to be particularly horrible life forms, but because we're just not worth bothering with, at least not yet. There is also the possibility that any intelligent extraterrestrials don't want anything to do with us, because of the potential of our hostility. Furthermore there it's always possible that we're still so primitive any extraterrestrial species doesn't consider us intelligent. Aside from the possibility that we're so primitive that dealing with us would be dangerous just on principal.Marik2 said:Aliens would probably be closer to what these guys are talking about

I think we're thinking too small when we imagine aliens investigating planets using actual living explorers. Bostrom posits that von Neumann probes - self replicating spacecraft controlled by an AI program - would be the most likely method, and obviously these drones would be able to cover the galaxy a lot faster than individually manned spacecraft.KyuubiNoKitsune-Hime said:I think that Calvin and Hobbes quote is probably the closest to true.
