If all objects are traveling at different speeds do objects pass time at slightly different rates?

All science suffers from a fatal tendency: scientists desperately want to be certain, even if they are wrong. For instance when I taught electronics I told my classes that a magnetic field expanded and cut across a conductor and that induced a current. Well, that is baloney: fields don't expand. They don't move at all. And there are places where you can't measure any field at all, but the current gets induced anyway, exactly AS IF the field expanded and cut across a conductor. So we have this picture of space bending and time being a variable constant. It makes no sense, but it's certain, so nobody is looking for any better explanation.
