Let’s say someone invents a ridiculously high powered projector. With this new tech, Coca-cola decide to do a Christmas publicity stunt in which they illuminate the face of the moon with their branding.
Is there an international law that would stop them? What would the penalty be?
Optional extra question: how close are we to the technology needed to achieve this? I’m guessing out powering the sun would be pretty difficult but of course there’s always the new moon.
