What If You Kept Getting Older and Couldn’t Stop?

What if you never stopped aging and could never die? You're 25, standing on your street, and every second a year goes by. You watch the future of Earth unfold year by year: flying cars, robot cities, AI replacing humans, an asteroid impact, a world reclaimed by nature, a new intelligent species, and finally the death of the Sun billions of years from now. This is a 3D animated "what if" timelapse of the next 14 billion years, seen from one street: what happens if you live forever and watch time pass at full speed. Have you ever wondered what Earth will look like in 1,000 years, in a million years, or in a billion years? What happens to cities after humans are gone? When will the Sun become a red giant? This video answers those questions, one second at a time. How old would you want to get? Tell me in the comments. Subscribe for more "what if you couldn't stop" videos.

The asteroid that ended the dinosaurs (Chicxulub) was about 10 km wide; its impact caused global fires and years of darkness and cold. The Sun slowly gets brighter; in roughly a billion years Earth is expected to lose its oceans. In about 5 billion years the Sun becomes a red giant, swallowing Mercury and Venus, then sheds its outer layers and leaves a white dwarf. New stars form from gas and dust enriched by older, dead stars. The universe is about 13.8 billion years old. The future scenes (flying cars, AI and robots replacing people, the orbital ring, the new species, the passing star) are imagined. More from this series: What If It Kept Raining and Couldn't Stop?
