>>18160549Not my preferable solution, just a solution I've heard of. In any case it's unlikely ayylmaos would just park just by the ISS and say "take us to your leaders" and start levitating cows.
My preferable solution would be mines orbiting the higher orbits of the solar system, autonomous "mines" that would hide between space rocks would kamikaze at anything that moves into the solar system. But that would require tech we don't have atm and so a relativistic rocket that moves at any % of c.
