So then make that specific narrow claim, not your overly broad claim that there are no massless objects in Newtonian physics. There manifestly are such objects even if they fail some specific criterion that massive objects fulfill.vanhees71 said:There is no physically interpretable dynamics of massless objects in Newtonian physics.
However, I disagree with even this more narrow claim. With a massless spring we determine the spring’s motion and internal energy. What dynamics are missing? What more dynamics do we get for a massive object?
