I Simulated Venus’ Past: From Oceans to Hell | Universe Sandbox

What if Venus once had oceans? In this video, I run a series of simulations in Universe Sandbox to explore what early Venus might have looked like — and how it transformed from a potentially habitable world into the hottest planet in the Solar System. You’ll see: ocean formation, the runaway greenhouse effect, and the loss of water with rising CO₂ levels. Enjoy watching! :) ━━━━━━━━━━━━━━━━━━━━━━━━ 💥🌌 All space experiments in Universe Sandbox    • Universe Sandbox   🚀🌌 All space journeys in SpaceEngine    • SpaceEngine   ━━━━━━━━━━━━━━━━━━━━━━━━ 🕓 Timecodes: 00:00 – Could Venus have been habitable? 00:20 – Early Venus: ocean formation (4.5–4 billion years ago) 02:27 – Unstable Venus: oceans start boiling (4–3 billion years ago) 04:17 – The point of no return: runaway greenhouse effect 06:39 – Orbital effects: Venus on an eccentric orbit 09:22 – The end of oceans: forming modern Venus (3–1 billion years ago) 12:58 – Conclusion: how Venus became a hellish world
