Forget "Armageddon" and "Independence Day"! In Roland Emmerich's "Moonfall," aliens simply steer the moon onto a direct collision course with the Earth. Aliens or not, this raises a number of scientific questions: Could the moon really be moved out of its current orbit (or be moved) so that it crashes into the Earth? And if so, what would that require? Jack Pop clarifies this in this episode together with physicist Sina from the channel @SonneTodSterne #moonfall #rolandemmerich #sciencevsfiction Sina is a physicist and has a very cool space channel on which she plays out all death scenarios in space.
