Right now, more than twenty billion kilometers away from Earth, something built by human hands is doing something it should never be able to do again. In the freezing silence beyond the heliosphere, where temperatures collapse toward absolute zero and cosmic radiation never rests, a relic from another era has broken the quiet. Voyager 2, a machine designed in the 1970s, officially dormant, abandoned to the dark, has sent back a signal. No commands were sent. No systems were supposed to be alive. And yet, a heartbeat appeared on NASA’s screens, steady, deliberate, impossible. Inside that signal were coordinates pointing to an unexplored region of space, and signs that Voyager 2 may not have been alone out there after all. What followed would force scientists to confront an unsettling idea: this was not just a malfunction, not just a ghost signal, but the confirmation of something humanity has quietly feared since the day we first looked into the void.
