To launch "3 Body Problem," the new Netflix series depicting humanity's battle with a cosmic threat, we recreated in real life the hack executed by the aliens to communicate their message to Earth's inhabitants. But we didn't do this on just any screen. We chose the trendiest and most buzzed-about screen on the planet: the Sphere in Las Vegas, packed with Easter eggs for fans (and even one for Morse Code experts!). And to top it off, we even CRACKED the Sphere.
