Science Question

posted by .

Our class is studying the concave earth theory, which are our teacher suggests is the most viable theory for understanding the composition of the earth and the universe as a whole. However, I am having a difficult time comprehending the concave earth theory and how it would impact gravity. Can anyone help me grasp what the concave earth theory is and what scientific evidence it has in its favor?


Ask your teacher for reference material. If this is a new name for the Hollow Earth theory, it has a following of several thousand nut cases.

Huh? No, that's not exactly it, but close. It's the theory that we actually live inside the earth, and that the entire universe is contained within the earth. That's as far as I understand it, at least.
