What would happen if the moon was split in half?

If the moon were to be split in half, it would likely have several significant consequences.

1. Change in gravitational pull: The moon's gravitational pull on Earth plays a significant role in ocean tides and the stability of Earth's orbit. Splitting the moon in half could alter its gravitational influence on Earth, potentially leading to disruptions in tides and changes in the Earth's axial tilt or rotational speed.

2. Debris and impact: Splitting the moon in half would release a large amount of debris into space, potentially leading to an increased risk of impacts with Earth or other celestial bodies in the solar system. This could have consequences for both Earth and other planets in the form of impacts and potential changes to their orbits.

3. Effects on Earth's climate: The moon plays a role in stabilizing Earth's axial tilt, which helps regulate the planet's climate. Splitting the moon in half could disrupt this stability, potentially leading to changes in Earth's climate and weather patterns.

Overall, splitting the moon in half would have far-reaching and potentially catastrophic consequences for both Earth and the rest of the solar system.
