particles (not??) following geodesics in GR
In a three-month old thread

one of the tutors ("atyy") said:
"And GR in full form does not have particles traveling on geodesics..."
What does that mean? How can a free particle deviate from its geodesic?
(Or was it implied here that particles were interacting with fields other than gravity?)
Many thanks,
Michael
