Light travels at one hundred eighty-six thousand miles per second. Fast enough to circle Earth seven times in a heartbeat. And yet, across the galaxy, it is painfully, hopelessly slow. A signal from the nearest star takes over four years to reach us. A ship moving at light speed would still need one hundred thousand years to cross our galaxy alone.
Tonight we map the cold engineering truth behind alien silence. The crushing fuel math. The dead worlds between stars. The reason every civilization, theirs and ours, may be quietly trapped. If you want to know why nobody has come, hit subscribe and stay close.
Strap in. The mission begins now.
