What Will Happen in 1 Billion Years?

From 2100 to 900 million years ago: cities, supercontinents and the slow end of life on Earth.

This video is a journey through the future on a human, geological, and cosmic scale: the population peak around 2100 and the changing urban landscape, structures designed to last millennia like Longplayer or the Pyramid of Time, and a sky transforming with new guiding stars and unrecognizable constellations. As the millennia advance, climates like a tropical Sahara return, rare but inevitable threats appear—supervolcanoes and asteroids—and an Earth unlike anything we know takes shape.

Then the clock speeds up: moons colliding, Betelgeuse exploding as a supernova, continents breaking apart and reassembling into a new supercontinent, and a planet increasingly constrained by the Sun's growing luminosity. Between the end of eclipses and the collapse of CO₂, photosynthesis ceases to sustain the world, and life fades away until only microorganisms remain. Thinking about all this doesn't change the planet's fate, but it does make us acutely aware of the true weight of our present.
