I mean, they have to, no? To the best of my understanding, gravity isn't a force, it's the bending of space around us caused by mass. Everything is forever moving in a perfect straight line from its perspective, but that line is curved depending on the mass of nearby objects, which affects the speed of movement (time). We're all moving around the Earth, which moves around the sun, which moves around the galaxy, which moves around the universe. This includes all particles which makes up everything. The idea that the gravitational field has no effect on them makes no sense. The question is simply "how much" of an effect.
- stevenjgarner 3y agoI struggle with this too. Is gravity a force or a geometry? (or both?)
- analog31 3y agoI have a physics degree, and struggle with it too. Granted, my degree was 30 years ago and I've been working in industry, so I haven't maintained my theory chops. The way it was explained in our graduate QM class was that certain operations in QM theory only work in Cartesian space. This is probably an over simplified statement of a Hard Problem, which is that QM and gravitation are both known to be exquisitely accurate theories, but mutually incompatible.
