Actually going to catch up to Voyager 1 before it gets very far, at its current velocity, it's 40,000 years to the next star for Voyager 1, which would be at least four complete human civilizations back to back, very likely to pass it, even after a contervalue nuclear exchange and prolonged recovery in the wake of it, could probably have several nuclear wars, and still recover in time to catch Voyager 1 before it actually gets anywhere.
Eleven billion miles away is basically the same place for all intents and purposes astronautical, in cosmic terms, Voyager 1 hasn't really moved at all.
I mean, there are over seven billion people on earth, could wipe out a billion and barely even notice that anybody was missing, a nuclear war would only be about one hundred fifty million, which wouldn't even put a dent in it. As recently as 1850 there was only a billion people on earth, you'd have to have two dozen nuclear wars just to get back to something like that.
Bear in mind, Fermi was a non hacker, he was "appalled" at even the idea of a hydrogen bomb, so he went peacenik on you, can't trust his calculations, it's all tainted by ideological bias, as if all the alien races in all the galaxies couldn't have survived the relatively minor in the grand scheme of things impact of some sort of global thermonuclear war, get real, Enrico, ya fuckin' bolshie sympathizer.
I mean, fuckin' Manhattan Project, it was a buncha commies, foreigners, and Jews, can't rely on anything they said after the war, they all went Beatnik and started shilling for the Reds, "ZOMG hydrogen bombs, quick, let's all capitulate to the Soviets to save the world from the Fermi Paradox!"
I see what you did there, Enrico, ya fuckin' turncoat.
