The Terrifying Truth About the Voyager Journey | Brian Greene

Описание: 40,000 years later, we know it. Right now, as you read this, two small spacecraft are hurtling through the darkness of interstellar space at over 35,000 miles per hour. They've been traveling for nearly five decades, and they've crossed a boundary no human-made object had ever crossed before—the edge of our Sun's influence, the border between our solar system and the vast emptiness between the stars. Voyager 1 and Voyager 2 have revealed something terrifying about the universe we inhabit. After 47 years of travel, moving faster than any bullet, they've covered less than 0.1% of the distance to the nearest star. At their current speed, it will take 40,000 years just to pass near another stellar system—not arrive, just pass by. The data they've sent back has shown us that interstellar space is stranger and more hostile than we imagined: higher radiation, unexpected magnetic fields, cosmic ray storms, and a void so empty it defies comprehension. In this video, I explore what the Voyager journey has truly revealed—about the terrifying scale of cosmic distances, the loneliness of our position in the universe, and the haunting beauty of two small machines carrying the sounds of Earth into an eternal silence that may never be broken.
