These tall building structures are batteries that are charging up the portals in the sky. The portals are made to connect to various dimensions and worlds where beings can travel to and fro with ease. I wonder if we are able to create such portal technology. Instead of traveling ultra-far distances and spending light years to reach a planet. We can simply go through a portal and reappear on the chosen planet’s destination immediately. If you miss your home on Earth, you can just go through the portal again without hassle.
