In this enlightening discussion, Prof Sara Russell, a planetary science expert from the Natural History Museum, Prof Neil Comins, an astrophysicist known for his work on the Moon's impact, and Prof Katarina Miljkovic, a planetary collisions researcher, dive into the Moon’s critical role in shaping Earth. They explore fascinating hypotheticals: life without the Moon, the effects of potential dual moons, and the geological contrasts between the two bodies. Their insights reveal how the Moon's presence governs tides, inspires exploration, and preserves cosmic history.
