An Advanced Civilization Could Resist The Accelerating Expansion Of The Universe - MIT Technology Review

Death, taxes, and an expanding universe. All are inevitable, but the former two are immediate threats. The last one is procrastination-worthy. Or is it? According to Fermilab's Dan Hooper extraterrestrials oughta make hay while the sun shines, or at least collect all those suns into an exastructure. It's like a megastructure on steroids, the likes of which stain Freeman Dyson's boxers every single night. Better yet, Dan lays out how puny humans can spot traces of these engineering marvels. In the meantime, we'll occupy ourselves with little things like interstellar asteroids. Or comets, as that Speeding Interstellar Object 'Oumuamua Is A Comet not an asteroid. Funny old thing, notes Jake Parks, "it’s currently traveling faster than is predicted by celestial mechanics". Things get stranger, nudging mainstreamers and mavericks to reconsider 'Oumuamua as a starship. Heck, NASA's already toying with the idea. (CS)
