03. Why does Earth have gravity and space doesn't? Is there any chance that Earth could ever lose gravity? (A K2S Question)

From The Space Library

Earth has gravity because it has mass. Space is a void and therefore has no mass, so it cannot have gravity. As long has Earth has mass, it will continue to have gravity. If Earth were to lose its mass, it would cease to exist, so there's really no way that Earth can ever lose its gravity.
