Ghosts of Space: The Loneliness of Signals
COSMIC GHOSTS: Why The First Aliens We Find May Already Be Extinct
In the vastness of space, our messages travel at the speed of light - but even that might not be fast enough. This video explores the sobering reality that by the time we detect signals from an alien civilization, they might have disappeared thousands or even millions of years ago.
Consider this: our radio signals have only been traveling outward for about a century. Any civilization detecting us today would see Earth as it was during World War I. With our galaxy spanning 100,000 light years, potential alien neighbors could rise and fall before their first "hello" ever reaches us.
What does this mean for the search for extraterrestrial intelligence? How might we detect civilizations that no longer exist? And what would it feel like to make contact with the ghosts of a species that vanished eons ago?
Join us as we explore the haunting concept of "cosmic ghosts" - civilizations whose electromagnetic echoes continue long after they've disappeared, and what this means for humanity's place in the universe.
