At least, this is my not-particularly-knowledgeable understanding of the issue. | |

In particular, when falling directly towards the center of a massive body (so, for example, excluding being in orbit about the body), two objects falling together will tend to approach each other, whereas in outer space they'll remain the same distance apart.
