The Forgotten Planet That Gave Birth to Our Moon: Theia

🌙 The Forgotten Planet That Gave Birth to Our Moon: Theia The Moon has been beside Earth for billions of years, but its origin points toward a world that no longer exists. Around 4.5 billion years ago, a Mars-sized protoplanet named Theia may have collided with the young Earth in one of the most consequential events in the history of our planet. The impact would have released enormous amounts of energy, vaporized rock, and thrown molten debris into orbit. From that material, the Moon may have gradually assembled. But Theia raises a deeper mystery. Where did the planet itself go? In this Snoozy Space documentary, we explore the giant impact hypothesis, the formation of Theia, the Moon-forming collision, and the evidence preserved in lunar rocks. We examine why the Moon has such a small iron core, why its chemistry resembles Earth's so closely, and why scientists continue to investigate whether remnants of Theia could still exist deep inside Earth. We also explore the mysterious structures near Earth's core-mantle boundary, the ancient planetary conditions that allowed the Moon to form, and what modern lunar science has revealed through Apollo samples, spacecraft observations, and geophysical studies. 🌌 Theia was never photographed. No confirmed fragment has been identified and placed in a museum. Yet its possible existence can be reconstructed through physics, planetary dynamics, geology, and the chemistry of the Moon. The story of Theia is ultimately a story about how planetary destruction can create something that survives for billions of years. So tonight, settle in and journey back to the earliest Earth, when the Solar System was still forming and a vanished planet may have changed our world forever.
