Being in outer space.

    It just got me thinking, if I were to be in outer space, and assuming there's no gravitational pull from some other mass, or it's negligble, then to what would I fall, and I don't see how I can move cause I wouldn't have any leverage.

    Wouldn't I be at constant rest?

    I would say yes.

    Well, you have the right idea, except that "constant rest" implies absolute velocity (of zero in this case) which does not exist.

    That is, there is no such thing as "absolute rest" which I interpret to be what you have to mean when you say "constant rest".

    No matter where you are in the universe, including where you are right now OR if you were in intergalactic space well away from all gravitational bodies so that their attraction on you is negligible, you would STILL be traveling a speed N relative to other bodies, and "N" can be anything from zero up to almost the speed of light.
