Interestingly, however, is that it is possible to pick a frame of reference such that gravity disappears, so it too is a fictitious force in a way.
I am not a physicist but that seems wrong to me or at least imprecise. You can select a frame of reference that makes gravitational forces disappear locally but there is no frame of reference that makes them go away globally.
