Is our earth hollow?

The core of the earth is molten iron, very hot., the heaviness of it stabilizes Earth. From the core mantle to the top crust Earth is full, there is no hollow space .

No

Why do you feel the need to ask a dumb question?

No?? There is a core that is solid

No one has ever digged down to see is it really! So can't say

No. If it was hollow we wouldn't be here having this conversation. We'd all fly off into space. In fact, life would never even have existed on Earth.

Just like people's heads.

No it's flat man

No, there is actually iron in the middle which is about 15,000 degrees hot
