Instead, different areas – like an ocean inside the Earth – can change how strong that structure is. As a result, gravity can have an effect on the Earth’s crust by changing these structures ...

This is where it leaves a tangible imprint, evidence that there exists a force more powerful than gravity at work within the Earth whose influence extends very far. Way back in the earliest ...

Isaac Newton - isn't he the guy who discovered gravity? Great! So, what's gravity? Aaaah, gravity is the force that makes objects fall towards the ground. And, without gravity, we'd all float!

It is as big inside as a house with five bedrooms ... pulling all objects with mass toward each other. The Earth's gravity is what keeps you on the ground and what makes things fall.
