    if proven beyond a shadow of a doubt, then all of humanity kinda ceases to host large scale conflicts among themselves. sure people go crazy for a bit and ape out but 50 years is a long enough time to think rationally and prepare. We will see the fastest technological growth and R&D program our species has ever seen. The most logical and cost effective method for fighting interstellar aliens is to probably attach gigantic rocket boosters onto asteroids and try to steer them into any oncoming vessels before they get past Pluto. we would mine the moon dry of helium 3 to use as fuel, our nuclear stockpiles will go to space and propel half mile long tungsten rods at .25 the speed of light. So long as our understanding of physics is correct then there is absolutely no reason why this would not be an extreme threat towards a soacecraft, especially one travelling conventionally. if that doesn't work then we're basically fricked.

    Space Based N-2 mines from Evangelion. I know, it's an anime, but it was a pretty concise example of what I'd use. Produce hundreds, thousands of them if able. Scatter them around the asteroid belt and/or the zenith and nadir points of Sol, depending on what their vector is. When their fleet is roughly center unleash a nuclear hellstorm.

    If that doesn't stop them we are not capable of doing so, and the only option is surrender and hope they didn't come all this way to eat us or some shit.

    Make gigaton level nuclear weaponry/railgun technology based in space and pray they dont have some kind of deflector shield or something.

    Turn a suitably dense solar object into a giant frickoff casaba howitzer. Grab a near-earth asteroid like Eros, carve out a couple kilometers of empty space inside it and fill it with thermonuclear material. Not weak ass lithium-6, the D-T reaction is a pitiful 80 kilotons per kilo, this will be a stellar nuke which has twice the power. Use antimatter as your implosion device to kickstart a stellar reaction. Fill the hole with lighter and more porous material than the surrounding stone so your hundred-million-megaton explosion will have a preference in which direction. Top it off with a blasting cap, which will weigh millions of tons and be travelling at more than 1% of lightspeed. Fake surrender as they entire your solar system, with no space fleet in orbit, and then fire off your moon killing casaba howitzer at the fleet as they enter gun range.

    We have to assume worst case scenario which would be von Neumann devices in which case our only hope would be to eliminate them before/immediately after they gain purchase on any mass in our solar system. Detection systems and nuclear launch capabilities for anything inside Neptune would be a minimum. Jupiter and Saturn with their associated moons /rings would provide many footholds into our system. Solar wouldn't provide much power that far so radiant reactors are more likely power sources, making detection a little easier. Once they're in the inner system we've already lost. There's too much mass and too much free solar energy to compete. The first priority would be launch vehicles. We're gonna need a lot of stuff outside our gravity well.

    Well then I assume they have found a way to break into another dimension so they could make a worm hole to get here. Unless I'm to believe they have traveled a few million light years without wormholes which would be even less believable than worm holes.

    Anyway our best defense with current tech would be to gunk up lower earth orbit with as much space debris as humanly possible so they couldn't make entry. When it comes to fancy space shit us humans are lacking hard. Then we just fight it out indefinitely on earth until we end up nuking everything in a zero sums game.

    >Aliens from another planet are coming to earth with hostile intentions, but do not have FTL.
    To cross interstellar distances in anything approaching a reasonable time (by sublight standards that means hundreds OR thousands of years instead of millions) you would need a drive system that is basically on par with a machinegun that fires thermonuclear bombs for months. This is physically possible, but not for us at this time. Any hostile alien that had that power could curbstomp the whole planet without even slowing down or curbstomp us by slowing down with their exhaust aimed at us. Our most advanced weapons wouldn't be quite as bad as spears vs tanks, but also not as good as a medieval army vs automatic grenade launchers. Aliens with the capability to travel interstellar distances are likely a once in a galactic lifetime event because once you cross that last boundary you gain access to the material wealth of your entire home galaxy.

      Pellegrino's "ship on a string" with pure anti-mat engines is probably the functional limit of what thermodynamics is capable of, being very optimistic on how efficiently energy from antimatter reactions can be captured. It inspired the ISVs from Avatar actually. Even if you manage stellar fusion (particle velocity of 12% of c), don't add any reaction mass, and have a really ugly mass ratio, you're never going to get faster than 20% of lightspeed, and you will accelerate VERY slowly. Antimatter (or blackholes maybe?) is basically a prerequisite to interstellar travel if you don't have some kind of FTL method.

      The dark forest theory only makes sense if you imagine everyone is confined to a single planet. As soon as a species is spread across multiple star systems, the idea of "detection = extinction" stops making sense, because everyone can't be wiped out at once, and anyone who did commit such an act of war would eventually get located and stomped by the survivors (or by whatever second strike systems they left running in deep space), making the whole "ree I destroy your home system" thing suicidally stupid.

      There is no particular reason to hide your presence in that case, either, because any intelligent life would reach the same conclusion (if I blast this source of communications, I am NOT getting rid of their civilization but merely provoking them into a war of extermination with me).

        How do you figure? Dark forest strikes leave no traces pointing to their origin, and even if they did, they seem to usually be fired from stealth, self-propelled weapons platforms. Only a stupid civilization leaving curvature trails in close proximity to their bases (either from a supraluminal projectile or weapon) would be at risk.

    Flawed unrealistic premise.

    They can't care for our planet because our biology is alien and worse than colonizing a random moon.
    The technology needed for manned interstellar imply they can live literally anywhere they want.
    The only hostile intention that would matter is extinction of other race, which can be done much easier without leaving your system.

    Also "kill everything that differ from you" is not a viable strategy, as survival require multiple individual and making more colonies to avoid extinction.
    A survival strategy which, without FTL comm is not available for an hostile race who would want to preserve their unity.
    You could try a Berserker killer swarm strategy but without FTL comm you will lose control and plain mutation will result in the killing swarm killing you (or you running out of resources in the home system).
    Or maybe the swarm going sentient and deciding they want to be benevolent pacifist instead.

          Assuming the universe doesn't want to let go of either relativity or causality, a warp drive is going to have issues if you run it into your past light cone (aka a place where you can effect your past). I wonder what happens when you do that.

            Alcubierre Drive mathematics don't seem to effect the past, they imply warping the universe's fabric in front of you. I'd be more concerned with what that effect does to things like planets with a large enough drive unit. Also, buildup of X-rays at the front of the wave may sterilize solar systems but YMMV.

    WW2 style anti aircraft fire into space but with nuclear missles

    If we know the direction and speed, begin making a bunch of mass drivers on the moon or other relatively low gravity body. Start taking a bunch of stone, put a small explosive in it on a long timer with a nuclear battery or other long-lived power source, and fling them out on an escape trajectory (rocket assisted if need be) to detonate just slightly in front of the incoming fleet. A flak wall traveling at relativistic speeds is going to make anyone upset no matter their technology level.

    basically if that's the case we just shoot them as usual after 50 years and the government goes back to its usual job of raping and pillaging the middle class. out of the news cycle in under a week. actually, adjusted for attention span deflation, it'd be out of the news cycle in 30 minutes if we look 50 years ahead

    Give them Mars or Europa, help them set up the colonies and start trading. The Solar System is big. With hundred of mineral-rich dwarf planets and asteroids and hundreds of places that you can harvest and filter ice and water. We don't have any actual need to take an offensive stance. If they can make a interstellar habitat that is good enough, they can make a swanky stationary colony, or even a really really good planetary colony.

    We have made wolves, cats, even crocodiles into friends before. Apex predators that in any other curcumstance find us better as a meal than as a friend. A species that can do that would be able to reach out to the stars and find friendship among those who have found their way to us through the dim and loneliness of the void with ease. We will find friends.

      Alternative:
      They take every other planets/moons because we don't have the technologies to stop or hinder them.
      They are vastly smarter than us and will quickly and easily find reasons to not share technology with our warlike species (unlike them we aren't unified).
      They will pretend to come as friend, they will suggest plenty of way to disarm ourselves & fix our planet, it will only be a side effect that our technology stagnate or become overly reliant on stuff they produce but we cannot retro engineer.
      They will understand our biosphere, cure everything, show us how easily they can sniff out our entire civilization with a virus without ever endangering themselves.
      Any act of rebellion against them will be shown as proof of our warlike tendencies that need to be curbed.

      Eventually Mankind will have to be fixed before they are allowed to go into far in space.
      However this happen, the alien will be in control of the process, it will be gradual and we will be made to believe we are happier having them do it.
      Any idea that they might be manipulating our genome to be in thrall to them will be openly discussed and lead to the conclusion we human are not yet smart and organized enough to prove it is happening, and if it was, wouldn't it be the best path for mankind?

      Beside, Mankind was clearly wrong with their "Fermi Paradox" since they exist, even if somehow mankind were to kill the savior handing them help, they are way too late to survive the others alien.

    Can't you just make large projectiles with nuclear propulsion? You can probably slingshot them around the sun with solar sails for even more speed. Hundreds of 100 ton DU rods orbiting around the sun with nuclear and sail propulsion before being hurled at absurd speeds into the approaching craft should be damaging enough.

    largely depends on the aliens defense systems

    like what are there navigation systems? Can they avoid debris?
    do they have defense against rockets?
    do they have to come down to earth to fight us, or can they just fly over and destroy / control everything?

    They easiest way is probably just to build a bunch of humongous hydrogen bombs and prepare them in orbit for a launch
    hydrogen bombs have no theoretical upper limit on their size
    the tsar bomb had a destruction radius of like 20km
    it's almost impossible to build large scale, economical protection against nuclear bombs
    and making stuff radiation safe is another challenge - we could just make it a dirty bomb too

    but 20km destruction radius is plenty
    and 50 years are more than enough to get a few 100k bombs into orbit

    Next time, try to be an adult and keep the discussion on the right track. If you sprinkle “btw leftists are traitors” when you don’t actually want to talk about politics… you’re even dumber than you sound.

      >hate aliens
      >know that aliens would only enslave humans in order to simply kill off all the humans efficiently by using the race-traitors against the other humans before ultimately liquidating the political prostitutes after the other humans are extinct, instead of enslaving them perpetually, besides, humans make better bosses anyway
