Allow me to preface the following with an apology if the question I ask sseem a bit off.
While reading Coming Of Age In The Milky Way by Timothy Ferris I came across a line in which he states:
"Earths gravitational force extends from its center point"
My understanding of gravity is that it is nothing more than curved space-time. The mass of objects warp the space-time and that warping is what produces the attractive force. Why would the Earth's gravitational force extend from its center point. How can the center of the Earth warp space-time unless space-time exists within the Earth at its center? Wouldn't the outer edges of Earth's surface be the source of the space-time warping since that is the area which comes in "contact" with space-time?
