Is The Moon Really Hollow?
Is the moon really hollow or is it filled with fluids (like water)? All the investigations related to the moon are showing us that the moon is not really full as we thought before but instead it's hollow, which means that there's nothing inside. But I don't know about that, I thought that the moon was like earth and it had a core inside.
So what do scientists say about this? Is the moon hollow or is is composed of some element?
