I think this has already been done.
The majority of us would probably resist and we would be crushed like bugs.

 

Course we wouldn't surrender. Until it was too late. Too many pansies around to say fight to the end - and they would be the ones who be around at the end as well.

 

If the Imperium found us as we are now, they'd probably declare exterminatus on us purely because of Justin Bieber. Wouldn't want that taint to spread any further than one planet.

 

I would rather hope the Nids invade Earth before the Imperium. They only have to eat France to take up the surrender gene and were as good as dandy.

If the Imperium landed here they would declare us traitors for moving around little figurines of themselves around tiny tables.

 

If the imperium landed on earth...... where did they come from?

The most likely thing is that (unless they just open up on us and decide to wipe the planet out) we would be annexed into the Imperium and after recieving the advanced weaponary of the imperium the majority of the soldiers in our armies would be sent of the proove themselves, considering the current tactics and thinking of the main powerfull countries armies, they would be used as more elite forces than just cannon fodder, Although some still will.

Considering that the main commonground that anyone could have (other than being human) would be that both cultures mainly worship a singular god who is the father of mankind. Unfortunately some other religions would be wiped out or driven underground, pretty much any that polytheist ideas.

Actually, the Imperium was based on the Roman Empire before christianity took hold; so they were actually pretty lenient on religion. As long as you do not hold your god higher than the emperor then your religion should be fine. That's why christians and jews weren't treated so well in the early days of the empire.

So I believe it would be the other way round. Jews, muslims and Christians are going to be the ones wiped out or driven underground.

 

Didn't the Imperium absorb parts of the Interex, which was a technologically advanced human empire? I don't think we'd get Exterminatus. Rather I imagine we'd try to establish "diplomatic relations" with them at first, to which the Imperium laughs at the very concept of diplomacy and proceeds to forcibly assimilate us. We'd all be on some frozen hellhole clinging to our lasguns in a never-ending war against Orks a few years later.

 

If they did come and destroy us the Imperium would cease to exist since they just killed their ancestors. [Especially since they live on a renamed Earth and they live in the 41st millenia] They would HAVE to come in peace.

 

Terra is just the latin name for earth. Latin is most likely what is commonly reffered to as High gothic.

And dammit toalewa850, that was the point i was waiting to use on someone who would argue that the "imperium comes from terra"

 

High Gothic isn't Latin. It's an amalgam of various old earth languages, but with a heavy emphasis on latin.

He is not saying they we are the terra that the imperium spawned from. Merely that we could be a long lost element of humanity that came to believe this was terra.... IOW, stupid.

 

So theres alot of planets called Terra, all orbiting different stars but still called Sol and with a solar system identical to our own?

 

No, a world called earth which is similar in every way to the one we have now. Now quit nitpicking and get one with the mans question.

 

What I meant by saying Earth was that Terra and Earth were seperate. As if The Imperiums world (Terra) is a completly different one than our own (Earth)

 

I think in some respects our technology surpasses the Imperium. I think modern main battle tanks would compare well to a Leman Russ, the latest fighter craft, while being slower if you go by the FW stats for thunderbolts and lightnings, don't seem far off the capabilities those craft. I think if it came to a straight fight we'd do pretty well, but then you factor in the orbital support available, never mind SMs, it really flips it on it's head.

However, I think once the various governments realised just how badly out gunned in that regard we are, and that we wouldn't be wiped out if we just fell into line, they would capitulate. There would of course be pockets of resistance, but they wouldn't last long.

 

If we resisted, we would be fucked... Our governments would never understand what we could gain from joining the Imperium of Man... They would resist... And lead us to our doom...

But that can be prevented...

There is a reason why I should be the leader of this planet...

 

I guess we know when Doelago has accomplished his latest task of being leader of planet Earth when he addresses us as a Grey Knight!

 

Moment they were detected in orbit the pres would be in a bunker. Don't know about your queen, not like it really matters much, but the US president would be safe.... for a short time anyway. US and Russia would probably just nuke the bastards. Well, they would try at the very least.

 

Royal family would be in Pegasus along with the PM and Cabinet.

I've only ever seen 1 reference to nuclear weapons in 40k, how would the shields on a imperial cruiser fare against them?

 

Idk. One? Probably do ok. 10? Guess is that it wouldn't do all that well against them.

 

It would be cool to watch the drop pods fall lol

 

Well, there would be resistance at first. We might do pretty well nuking them at he start, but when the SM come down, they'd probably decimate a major country or something. In the worst-case scenario, either we go all up against them and they declare us heretics and spawn of Chaos and Exterminatus us, or just denounce us as heretics straight away and Exterminatus us. Assuming this doesn't happen or they don't Exterminatus us, (they'd probably recognise the galactic coordinates of Holy Terra, and therefore want to preserve it) then any long wars would be doomed to failure. The Imperium has 1,000,000 Space Marines and hundreds of thousands of millions of billions of trillions of Imperial Guard. This wouldn't be a war we'd get out of easily, and the situation here would be like on Cadia in the sense of these two quotes:
"The birthrate and recruitment rate on Cadia are synonymous..."
"Any child on Cadia who can't strip, reassemble and fire a lasgun before he can read was born on the wrong planet."
Even with this, we might end up barely coming out, not just because of the Imperium's far superior numbers but also because of CREEEEEEEEED! (Though it is possible we could match Creed, since modern tactics are far superior to 41st Millennium tactics and our tacticians would be tactical geniuses by 40K standards.) However, most of the IG will be up in their ships for most of the time so a few nukes and missiles into the Imperial Navy could tip the balance in our favour.
Eventually, we would probably still end up losing (damn you Space Marines and your overpowered statlines and special rules!) and we would have to accept the God-Emperor as our rightful saviour and protector before he's even saved us. Life as usual, 40K style, and we both contribute something to the other. The Imperium gives us Warp travel and the opportunity to ply the stars, we give the Imperium better tactics and some scientific innovation. A couple of revolutions will spring up, and I know for a fact that one will end up being quite large and then execute Robin Cruddace and Mat Ward for making IG and SM so amazingly overpowered. Others will probably have someone come in and say they're actually the Emperor, since for all the Imperium knows they could be as this is the distant past and the Emperor is probably among us somewhere. These rebellions would fail whenever they sprung up.
In a few millennia we would get up to the Dark Age of Technology, as our top scientists and the Adeptus Mechanicum finally manage to reverse engineer the weapons and technology of the Imperium and use this knowledge to pioneer the things that were left behind and not yet found in the 41st Millennium. Thus, we enter the Dark Age of Technology and we encounter the races that also exist in 40K. We reign supreme for another few millennia, then become like the Eloi from H.G. Wells' novel The Time Machine, or possibly more like the humans from Wall-E as our great technologies drive us into decadence and laziness. We fail to notice the encroaching threat of the xenos and Chaos, and then we are dealt a great blow. We enter the Age of Strife, and there would have been rebellions going on for all this time. At the end of the Age of Strife, one man is successful in his claims that he is the God-Emperor. By this time, many have forgotten that he existed, and the rest is history.
Thinking realistically, we see no threat in the large armies of 30cm tall metal and plastic miniatures, and after some petitions to the governments of the world by wargamers and hippies, we allow the Imperium to live, and we get one of the High Lords or Tigurius to tell us where they came from and how they got here. We then manage to get all the other armies out of the 40K universe, and after some persuasion (e.g. capturing major gods and leaders and keeping them in underground facilities) we get the armies to submit themselves to the service of wargamers, dividing them out between us. A rewrite of 40K is then put in place, a cloning system based on Dark Eldar technology is developed to make sure miniatures which get slain in your battles can come back, and also so that armies where there are not many warriors to go around can be given out to everyone. And 40K is now a lot more awesome.
If the Imperium is at real scale, and they're accepting diplomacy from us, then after a few weeks, maybe a month or two to give our answer to the Imperium's ultimatum the governments of the world send wargamers who play Imperium armies to go up and send our message and to swear oaths of fealty to the God-Emperor on behalf of the human race. In these few months, every wargamer has wisely switched to an Imperial army and we become the world leaders and generals in a new Golden Age of Humanity. 40K is reinvented as a means to test out tactics for battles and campaigns against xenos.

 

In all fairness, if it was a case of fighting on the ground only (no orbital stuff) we would win. the Imperial guard wouldn't be to happy when they see that our tanks (Challenger mk.2, Abrams m1a1 and the leopard II for example) can hit their tanks from outside their own range, are less of a target due to their smaller build and have stronger armour.

The guard would win battle due to massive numbers, but they would take some pretty damn heavy casualties due to the weapons we use combined with out tactics. And seeings that our planes would easily beat the imperial flyer, we would own the skies, so with the support of planes and helicopters ground battles might actually swing our way.

As far as space marines go, If a lasgun can has been seen to penetrate a suit of power armour, a normal 5.56mm round might strungle, but any of the bigger calibre ammunition wound probably get through, so 12.7/ .50 cal, 40mm grenades, 20mm & 30mm cannon etc. would probably do the damage. Besides, we have neutron bombs specifically designed to kill the people inside the armour.

The elite troops we have would be better than the elite troops that the guard have, sostrikes from them would be pretty effective against any groud based targets that the imperials would have, that combined with our arial support, naval capabilities and extreme long range smart weapons their supply routes and command structure wouldn't last to long once it has been located.

It would be most likely similair to the Halo universe in which mankind can win almost every ground engagement but almost always loses in the space battles.

Which is why it's unfortunate that the Imperium would be coming from orbit.

What do they care? They have more tanks than we have people. And really why are they deploying so far away from us? Drop it on their heads I say.

And seeings that our planes would easily beat the imperial flyer, we would own the skies, so with the support of planes and helicopters ground battles might actually swing our way.

Again, what do they care? The guard would be willing to blanket this world with their corpses if that was what it would take. They are perfectly willing to take these kinds of casualties. We are not. As soon as casualty reports start reaching civilians (which they will) you can expect massive backlash and a crumbling political will. They can and will sustain damages that we will and can not.

As far as space marines go, If a lasgun can has been seen to penetrate a suit of power armour, a normal 5.56mm round might strungle, but any of the bigger calibre ammunition wound probably get through, so 12.7/ .50 cal, 40mm grenades, 20mm & 30mm cannon etc. would probably do the damage. Besides, we have neutron bombs specifically designed to kill the people inside the armour.

Lasguns cannot penetrate power armour. Boltguns cannot penetrate power armour. Nothing shy of a hellgun (that word is better) can penetrate power armour. Guardsmen can occasionally kill marines by hitting them in the joints enough, unfortunately we don't have the numbers to just keep shooting at them while they butcher us.

The elite troops we have would be better than the elite troops that the guard have, sostrikes from them would be pretty effective against any groud based targets that the imperials would have, that combined with our arial support, naval capabilities and extreme long range smart weapons their supply routes and command structure wouldn't last to long once it has been located.

Why do you assume our special forces are better? No offense but how many of them have been raised from birth to kill? My money's on not very many. The Imperium breeds psyco-killers and super humans. People living on Catachan, Kreig or Cadia would all be superior (physically) to modern-humans. Thousands of years of selective breeding will do that.

Tactically we may be better but reading some BL stuff (Gaunt's Ghosts in particular) I get the impression that tactics aren't always that simple in 40k. Not to mention the fact that they have more tactical options than us, including another theater of war (orbit) that we can't even enter.

And as far as shooting nukes into orbit goes, good luck with that. We do not have the capability to launch nukes beyond our atmosphere. We do not even have the capability to go to the moon anymore. All the Imperium has to do is sit out there and occasionally shoot at us. Plus, I'm pretty certain that nukes are the standard in ship-to-ship combat in 40k (not certain on this) and so void-shields are perfectly capable of holding off at least a few. And if nukes aren't the standard than that means there less effective, because it means the Imperium rejected them as a weapon.

In conclusion. We'd be pooched. We wouldn't stand a chance.

 

Ah, about time I saw one of these.

I'm in complete agreement with Hoobit. Except that when the tides of war turned against us irrevocably -- we'd, the stubborn little bastards we are, would sooner send our world into nuclear holocaust rather than submit to non-democratic government. So the Imperium would win and inherit a radioactive wasteland and the millions upon millions, and thousands upon thousands, of Guard and Space Marine corpses.

On that note -- this is actually my 2012 Conspiracy theory, a long shot I know, but its unique. I do not believe the Imperium will find us -- but rather some other Human Empire with him we lost contact with hundreds of thousands of years ago.

Now ... how that particular exchange goes, it anyways guess.

 

Whatever happens, we (the 40k fluff fans) are all fucked, we have waaaaaaaaaaaaaaay to much information the inner working of chaos, xenos and the Imperium in general, including events they would rather us not know or have forgotten ^^

We are all doomed to spend our lives in some Inquisition cell, giving them all our info. Sucks to be us

 

"You say the Emperor is real? I don't get to be a Servitor do I? No? Cool, sign me up."

 

Space Marines teleport into the bedrooms of every major leader on Earth... the spinless, corrupt tramps immediately capitulate. The world’s armies gear themselves up for a big scrap... see ten Legion's of Titans striding across the battlefield surrounded by 1000,000 IG, 100,000 tanks, the skies full of Imperial battle cruisers... crap pants, lay down weapons. All Hail the God Emperor!

 

Space marine teleporters arn't that accurate. #And the world leaders owuld already be in their bunkers.

 

OK, teleport into the bunkers then! Problem solved.. :victory:
