What sort of scenarios do the defense ministries and departm

>>33732218
Kill it real good, if that don't work then fall back and ask science dudes how to kill the green dudes and do what the science dudes say.

>>33732218
IIRC they have some system through NASA or whatever.
In the event of an invasion, you better fucking hope you can shoot down their ships because if they get complete control of the space surrounding earth it's gg.
It's like a siege but they can fire on you from anywhere and you can't do anything about it.

A lot of money would go to better missiles.

>>33732294
Anything that has the energy to get out of their own star system can glass planets. There would be no battle to take place. It would be no more of a battle than you spraying raid on an anthill.
Luckily for us any being capible of exploring beyond their own solar system would more than likely be non interventionalist, and if for whatever reason they did want to make contact, would more than likely be very peaceful.

With our current understanding of physics we will never leave the solar system. Meaning 1 of 3 things.
1) Our math is shit and we don't understand how shit works
2)We need to somehow break the very laws of physics
3) (most likely) we will simply never leave the solar system. We shot the voyager probe in the 1970s, and it just passed Pluto recently. That fucker is hauling as at several hundred miles per second and it won't reach our next door neighbor for a few thousand years.

>>33732395
we could build a generation ship at our current technological level, it just costs too much.

Lmao. Take that shit back to rebbit.

>>33732494
I agree. Whilst they may not be the sort to go full retard and wipe us out, I'm sure if they needed supplies, or samples, they wouldn't exactly feel the need to ask.

I think the story "The day the Earth stood still" is a likely way shit would go.

Remember, going full retard on humans only, is not exactly a bad thing for this planet, or every other lifeform.

>>33732395
Not saying you're exactly wrong here but your logic is deeply flawed. Just because something has the ability to go faster than we believe is possible doesn't mean it's equipped to fight a war or destroy a planet (outside of ramming it at extreme speeds).

The scenario you're describing (they would be too technologically advanced for fighting back to be useful or meaningful) is not necessarily the case, as history is full of instances where an exceedingly advanced civilization lost to a primitive one for any number of reasons, distance from support usually being the primary one. Of course,>>33732395
if an advanced civilization targeted Earth for destruction, it could easily just destroy the planet with a relativity-based weapon.

>>33732603
if they just managed to get a colony ship to a planet they had detected had a livable atmosphere at massive political and material expense and found there to be some spear throwing savages on the surface do you think they would turn around and go home?

>>33732218
It doesn't matter what plan any defense ministry comes up with because a war with aliens won't be a war it would be a one sided slaughter. A hypothetical alien invasion of earth wouldnt play out like any Hollywood alien invasion movie where the aliens have a unique weakness, capital ships flying at low altitude, a single command center behind the moon or other dumb crap like that.

To be able to achieve interstellar flight be it through faster than light speed, warp technology, etc their technology would be so advanced we might not be able to even comprehend how it even begins to function. It may even appear as "magic" to us. They would've spent years doing reconnaissance of earth's culture, technology and political structure so they'd know which countries are allies, which ones aren't and what's their overal military strength letting them come up with a plan on the best and fastest way to cripple Earth's combined military might. They'd identify and quickly destroy any military bases, industrial complexes, naval groups and other assets before we'd have a chance to retaliate and they won't do it from any low altitude slow moving flying space cruiser either they'd destroy all or shit from beyond orbit and maybe even beyond the moon using whatever crazy destructive weaponry they have. They don't even have to use weapons they can just redirect a bunch of astroids from the asteroid belt and send them to earth that alone would fuck our shit up so bad.

It would be like when the European colonized first came in contact with native Americans. Hope you're ready to see our women get culturally enriched as they steam roll our military

>>33732862
Depends on a few things:

The expense of said ship related to their "GDP". Such a ship may be of trivial cost. Think of an '82 Corolla... now think anout said car appearing in 1904.

Resource pressures in their home world (s).

Overall goals (colony, or just exploration).

Im sure they'll take what they need without our say so, but it may not be much/everything, based on what they actually need.

Unless they have some magic propulsion, they'll need to orbit. If they have to orbit and don't have magic armor ASATs fuck them up.

Orbit is not the "ultimate high ground", orbit is silhouetting over a hilltop the size of the horizon with no cover.

>>33732395
Only if you consider humans with nukes as a species able to glass planets.

If we had some desperate pressing need to leave Earth, we could absolutely leave the solar system. We could get to Alpha Centauri in a generation - parents and grandparents would be alive that remembered Earth.

But we don't need to leave, and nobody wants to go on that one way trip. Its Ideological, political and sociological issues preventing it. Not technological.

A long lived species, or one that had to leave their home planet might not have those issues.

>>33734674
>We could get to Alpha Centauri in a generation

Please dont make me elaborate on why that is a retarded statement, for your own sake. Even IF we had the technology to make that a reality(which we dont) it would take decades to build such a massive and complex vessel, let alone man and train a crew to operate the fucking thing. The best working concept we have is to build a giant ass laser beam in orbit to power a solar sailship that would take years to get up to speed, and the massive amounts of thrusters it would take to make course corrections, right there you are talking about a vessel capible of supporting hundreds of thousands of people, let alone the food and resources needed to sustain such a crew, maintenance personnel, and so on. With current technology you are literally talking about AT LEAST two extra atmospheric COUNTRIES.

>>33734916
Nuclear Pulse Propulsion can achieve 0.1c. Generation was the length of travel time, not to build it.

It'd expensive as fuck to build and destructive as fuck to launch but we don't have an existential threat causing us to focus on the manufacture of such a thing. There's no technological reason we could not if we had the impetus.

>>33734989
So you're honestly trying to tell me that we could literally source hundreds of millions of skilled tradesmen, engineers, scientists, biologists, military personnel, doctors, physicists, and so on... easily 1/10th of the earth's entire population to commit to a one way trip? What you are talking about is sending CONTINENTS into the void. Not to even mention the unimaginable amount of resources aside from human lives this would take.

>>33735302
Not that anon, but I don't believe he said anything about fitting 700,000,000 people onto a spaceship. That's just fucking absurd.

>>33735302
1) What part of existential threat do you not understand.

2) >>33735502 <- This. A very large ship can be built with NPP. A city sized ship if you like. But I was talking about an interstellar ark at its most grandiose, not an evacuation of an entire planet.

3) This is moving away from the original point - there is no technological reasons why you couldn't build an NPP interstellar ship with humanity's current level of technology. Only Sociological, Political, Ideological - and by extension of those 3, Economic issues prevent it. Issues that may or may not apply to aliens of an unknown culture and disposition. May not even apply to humans under extraordinary circumstances.

Therefore, no it is not an autowin, because no they do not necessarily have the technology to glass the planet by virtue of being able to get here.

>>33735302
What the fuck are you on about? Where did you get continents?

>>33732476
The nearest system that could have garden/golden worlds is Tau Ceti. 12 light years away.
Proxima Centauri B in the Alpha Centauri could be colonized but the odds of a planet in Tau Ceti approaching earth conditions are good.
As for our own Solar System it pretty much looks like Jupiters moon Europa is near habitable enough. Temps are near earth cold but o2 is low - atmosphere could be developed but it has been theorized that all one would need to walk around on europa is winter clothing (not even arctic tier) and a respirator. In Comparison it would take 1000 years+ to terraform Mars

>>33732395
>Implying Earth doesn't have any resources space hombreys would want
>Implying space hombreys would treat us any differently to how we treat ants

>>33735769
To elaborate Proxima Centauri is the closest star to our solar system, Proxima Centuari b is 4.2 light years - but Honestly Alpha Centauri is probably going to be a bust save for small outposts and mining - it's a 3 star system and Proxima Centauri is a flaring red dwarf

>>33732476
Anything in Alpha Centauri is going to be a complete bust for a generation ship - it's a 3 star system, any planet in it is getting roasted.
A generation ship is going to need near earth like conditions. Literally the only thing that comes close to earth in any degree that we have confirmed is jupiters moon Europa

>>33735302
6,000-10,000 people genetically prescreened would be enough to ensure enough genetic diversity for the generation ship to survive, provided it makes it to it's destination and the destination isn't a bust.

That said I think any generation ship is going to have the expectation that the home system will eventually burst though the limitations and hit FTL within 500-2,000 years of departure and reunite - saving them from genetic problems that could occur over millenia.

A generation ship is too risky at this time - it has to find a habitable planet and colonize with the limited resources it brings along.

The best thing we can do is push towards Europa right now

According to what natural law?
