Postcard From Earth At spherevegas #SpherePartner Sphere is the world’s most hi tech entertainment venue, built with 22nd-century tech and the largest LED screen on Earth. Inside, you can experience “Postcard from Earth,” a multi-sensory film shot in 40 countries. Say hi to Aura, the most advanced humanoid robot, and hear it all through the world’s largest concert-grade sound system. My wife and I had an incredible time, we were genuinely blown away by the quality! What stood out the most for me was how insanely clear and sharp the sound was. Definitely something I’d recommend adding to your list the next time you’re in Vegas.
