If the world is invaded by aliens...seriously..

I was looking at Jeff's amphibious sub fleet, with the titanic Typhoon like 40k mt subs that can serve as carriers, cargo ships, replenishment ships, support and amphibious ships, and all that can perfectly apply here.

And uh, it took 1 ferrite meteor to wipe off the dinosaurs, I don't think we'd live if the aliens did threw rocks at us [at Mach 30].

If aliens are willing to fight for this rock we call Earth, they won't be inclined to put it in an inhabitable situation. They must preserve the prize, in order to make it worth the expense of a campaign. My scenario would be limited, highly measured WMD use by both sides.

Letting loose biologicals may bite back at the aliens should it mutate, but they may introduce invasive species from their own world to ours that may end up adapting to our own biosphere and compete (eat) the local life (including us). Kind of like the scenario in the TV show "Surface".

Manipulation of weather patterns within our biosphere is something an invasive alien species may consider in order to make the planet more habitable for their own. The key to manipulating our weather, the first stage of a process called Terraforming, would lie in our oceans, especially with ocean currents. Which means the primary responsibility of defense for that would be our navies.

i maintain my view that there's only one solution, which can be elegantly summed up in two words: slimy tentacles.

you've already expressed your view in this thread so theres no use repeating it. I think I speak for about 6.5 billion people when i say that i don't relish the idea of going down on an friggin alien, which may or may not be your cup of coffee. Give then choice i think all of us would rather put up a fight.

Imagine Alexander The Great and his army fighting the full force of a modern army - with its machine guns, tanks, fighter jets - 3000 years from the future. Imagine again the world's modern army at present, fighting the machines of an alien's race with 30,000 years of civilisation and technological advancement. By the way, 30,000 years is nothing much in astronomical terms.

The only reasons they haven't attack us yet could be because they haven't found us yet, or they have the good alien sense of leaving us to boil in our primitive juices (in the words of Stephen Hawking)

If the aliens do decide to takeover planet earth, our only consolation is that they would not be very bad masters afterall, considering that they have survived that long in their own world without self destruction. Or maybe not.

I am kind of trying to imagine such races, maybe something inspired from the game Universe At War, where three alien races with distinctive technologies decided to settle their differences on Earth. Can an infantry man with machine guns and assault rifles deal with a mechanized alien in a hard suit carrying direct energy weapons? Can our modern tanks deal with Walkers spewing death from massive direct energy weapons? Can our modern fighters and ships deal with hordes of alien fighters and drones launched from massive motherships that float in the air effortlessly?

Or is it our own concept of an invading alien species is the one that is obsolete? It all sounds like Hollywood material.

A civilization that is far more advanced than ours may not view warfare as the way we view it now. We view warfare still in the hard kill, attrition and territorial take over. They may view it in more subtle terms, perhaps to even challenge their superior intellects by using strategies to force us to give up without a fight, the Sun Tzu ideal. Portraying themselves as gods and offering promises to turn the world into a utopia, and fooling the gullible to follow them would be one way. That alone would already divide the Earth population to fight one another.

OMG! it'll totally be like the goa'uld in stargate but but!...just no..-_-.

Far more believable is that we come into contact with a seemingly benevolent alien race which helps us to further develope and integrate our society only to have a dark agenda. E.G. gives us a vaccine to cancer with the slight side affect of making us sterile..BOOM! instant world take over and not a shot was fired. This idea i also got from stargate... but when one actually thinks about it, its far more credible then alexander the great coming to our rescue.

Here's an example of the kind of scenario your talking about. In the game UFO Aftermath your classic saucer releases a living fungi-like organism into the Earth's atmosphere that blankets everything, killing all exposed humans and then it starts growing, covering the Earth's surface.

Slimy tenacles?

Give then choice i think all of us would rather put up a fight.

Hail yea, just give me a F-15...er, pop rocks, dry ice, and soda.

or they have the good alien sense of leaving us to boil in our primitive juices

Say you what? What means that? Leaving us to our global warming and sterilising doom?

Looking back at history, what's the chance that 2 alien species finds us at about the same time and decide to pitch us around like the Burmese (or was it Indian?) princes?

I had actually talked to this "guy" and that will be the some of this information. But, here was the "guy" thought processes which is shared in this guys circle of knowing.

IF a Alien species has the ability to get from point A to Point B (earth) based on the the technology just to travel such a vast distance and IF these Aliens had intention of taking the earth for their own. Well, in all likelihood we would not even know we had been hit. That's how fast we would all be dead through means we can only wonder.

think about the best extermination company in the world taking out a small ant mound. thats the tech gap we are talking about.

Since alien biology is likely to be very different from ours, the solution is biological warfare. Fill the atmosphere with deadly (for them) viruses or bacteria, yet harmless to humans.

But really, the above poster is right.

Ok you asked for it.... Raptoreyes guide to creating a star spanning empire. (as opposed to terra-forming dead or pre-sentient biospheres which is more sane and much much easier. heheh

To conquer earth you will need these ingredients if doing so from a distant star. If you have a recipe book now is the time to take it out and take notes. Some of the needed things are hard to obtain. I wrote this from the aliens point of view for the sake of humor whenever I could reasonably do so.

1-- Unlike the Humans you need a culture that is very command and control based. The Zerg in Starcraft or the Formics in Enders Game would be best examples of this. These invaders could have large stockpiles the world destroying technology without the independence of mammals. Any individually independent starfareing species with faster then light travel would be very peaceful simply because any ones hostile enough to threaten other spicies would be rare. If your anti social enough to want to take another intelligent species home planet, then your anti social enough to destroy yourself with your own weapons too, in an internal conflict LONG BEFORE you become a threat to others elsewhere in the cosmos. Any wantonly hostile race would be one who was a hive or insect colony type race with one or two leaders and lots of servants lacking will of their own or ability to act with true independence.

2-- A reason to attack humans in particular. In other words any star faring race is also one that can "terra-form a planet" to the specifications of its species using space spanning technology. Humans are already talking about making Mars habitable for its species via a thickening of the atmosphere and out-gassing the water already detected on the planet. Needless to stay any member of the stellar community that could or would desire earth would be FAR MORE ADVANCED making terraforming far easier for them. Large Mirrors have already been discussed and one human Robert Zubren a noted astronomical engineer has gone through most of the math and tech needed to turn Mars into a living planet. Check out

This presents a real problem for the would be conquerers. Why take somebody else's stuff when the universe as we understand it now is very open and unclaimed. Most stellar bodies only need some "fixing up" with easy things like an atmosphere which humans can already replicate slowly on Mars. Now imagine an alien species that can have an army of nano-robots or something humans have not dreamed up yet to help you terra form largely from local resources fast and efficiently rather then the slow human method of primitive chemical engineering and mirrors and macro scale robotics that humans are now planing for Mars.

3-- Even if you had a reason to choose earth rather then some dead body you could alter.... you still need to terra-form your body or the planet earth so you can live on it.

If you wanted to conquer earth you would first introduce microbes into earths biosphere that could contend with and destroy earths microbes (but were harmless to the invading spices) Even early Sci Fi novels noticed that our biosphere's bugs would be very toxic to anything without an engineered resistance. Any Aliens we saw invading earth would likely be altered genetically to deal with known samples of microbes they might have collected in secret earlier. "War of the Worlds" after all was not won by earths military but by the cellular toxicity of its environment to the invaders. At the human tech level it would be harder for a space invader to ensure protection against earths very different single celled organisms then the aliens of a interstellar tech level would have with 5-15 Tomcat fighters, missles or ASTAT weapons the humans could launch.

Worse the Aliens might end up fighting human scientists in a battle where they had no advantage....the engineering of biological warfare organisms.

stay tuned for part 2
