You might be thinking of aliens stealing the stuff, or as NASA thinks, the rock had a chemical reaction in a way that made it disappear. It was a hard solid core that needed a […]

What is Earth’s Likely Construction?

This is tricky, as there are various views on the subject, but have settled down to a consensus. The traditional layered view may not be accurate though as when you get down close to the earth’s centre a lot of the force is not just downwards, but outwards too. At the very centre of the […]
