What would happen If the Moon Crashed Into Earth?

The Moon is falling toward Earth right now. It has been falling for four and a half billion years. That is not a warning, it is simply how orbits work. Earth's gravity pulls the Moon toward us every second, and the only reason it never arrives is that it is also moving sideways at just over one kilometre per second. It falls, and misses. Falls, and misses. An orbit is a fall that never ends. But what if it did end? What if the Moon lost its orbital velocity in a single instant and began dropping straight toward us? In this documentary we run that scenario properly, using real physics. You will find out exactly how long the fall takes, why the first day is almost silent and the final hour is catastrophic, and what those five days would actually look like from the ground. We explain why tidal force grows with the cube of the distance, and why that single relationship reshapes the entire planet long before impact. Halve the distance to the Moon and tides do not double, they increase eightfold. You will see what that does to the oceans, to the solid rock beneath your feet, and to every fault line and volcano on Earth. Then we cover the part most people have never considered. The Moon does not arrive intact. It crosses a boundary called the Roche limit, where Earth's tidal forces become stronger than the Moon's own gravity, and the Moon begins tearing itself apart in the sky. We break down the impact itself, an event releasing energy on the order of ten million times greater than the asteroid that killed the dinosaurs, and answer the question people always ask: does the Earth survive? The answer is surprising. And finally, the twist. Something almost exactly like this has already happened. Around four and a half billion years ago a Mars-sized planet called Theia struck the early Earth, and the debris from that collision became the Moon. The scenario in this video is the Moon's birth played in reverse. So should you worry? No. The Moon is not getting closer. It is dr
