If the moon suddenly split in half what would happen to people on Earth?
If the moon split in half, it would have catastrophic effects on Earth. The gravitational pull of the moon is responsible for the tides in our oceans, so the splitting of the moon would most likely cause massive tsunamis that could wipe out entire cities and coastal areas.
The sudden change in the moon's gravitational pull could also have effects on our planet's rotation, causing earthquakes, volcanic eruptions, and changes in the climate.
Additionally, the debris from the split moon could rain down on Earth, causing widespread destruction and potentially leading to the extinction of many species.
In short, the splitting of the moon would be a catastrophic event for life on Earth.
