If the Moon collided with Earth, it wouldn’t be a Hollywood-style instant explosion. It would be a slow, catastrophic gravitational event. As the Moon approached, tides would become extreme enough to tear oceans across continents. The planet’s crust would start to flex under the tidal stress, triggering global-scale earthquakes and volcanic activity. Instead of a sudden impact, the Moon would likely begin breaking apart long before contact, forming a massive ring of debris around Earth. Eventually, that debris would either rain down in a prolonged bombardment or merge into a temporary molten disk around the planet. The surface would partially melt, oceans would boil off, and Earth would be reshaped into a far more uniform, lifeless world. But here’s the key point: this scenario is effectively impossible under known physics. The Moon is slowly moving away from Earth at about 3.8 cm per year due to tidal interactions. That drift is stabilising the system, not destabilising it. For a c...
