We all share some common-sense notions about the world. One is that a second in London is a second in Melbourne - time passes at the same rate for everyone. Another is that the length of a rigid object such as a car, does not change. The truth is that space and time are not absolute but they stretch and warp depending in relative viewpoint. What is more, the presence of matter distorts BOTH space and time. If Earth wasn't where it is then there would be no GRAVITATIONAL PULL present. Look at it this way, SPACE IS A GIANT BLANKET AND STARS AND PLANETS "dent" this blanket when present, this "dent" is their gravitational influence on space and time.
