But you don't feel the force of acceleration. Floating weightless and motionless in space feels the same as being in an elliptical orbit around a planet.

- lupire 3y agoEven more, accelerating due to a being in an (idealized) rocket also feels the same. https://www.npl.washington.edu/eotwash/equivalence-principle https://www.npl.washington.edu/eotwash/equivalence-principle This has to be true, because if you can't (internally) detect the difference between nothing and a planet being nearby, you obviously also can't detect how massive the planet is, so you can't know if your acceleration relative to the nearby environment is due to gravity or something else, or even how much "absolutel" acceleration you have. Standing on earth (or the floor of your rocket) feels different due to electromagnetic effects of the nearby "touching" external objects.
