[00:00:00]The sun would seem to keep shining for 8 minutes and 20 seconds after it vanishes. For almost 9 minutes, you'd have no idea the world was about to end.

[00:00:10]That's because light travels at the speed of light. 300 zillion kilometers per second. And gravity? It moves at exactly the same speed. So, the sun's ghost would keep sitting in the sky while we drift free. The moment the last rays arrive, Earth's untethered. We'd shoot off into the void at 30 kilometers per second.

[00:00:32]No impact. No warning. Just cold silence in every direction. The moon would vanish from the sky seconds after the sun. Photosynthesis stops in an instant.

[00:00:42]No more new food for anything alive.

[00:00:45]Within 1 week, global average temperature drops below minus 20° C.

[00:00:51]Within 1 year, minus 100°. The surface of every ocean freezes solid. But deep below, kilometers down, hydrothermal vents keep pumping heat. There, in total darkness, ecosystems of tube worms and blind fish hold on. Not for years. Not for centuries. For billions of years, life doesn't need the sun. It just needs a little warmth from deep inside the planet itself. That ghost of the sun in the sky for 8 minutes and 20 seconds, that's the closest thing to a goodbye the Earth ever gets.
