Relative to what other object?
I was introducing an existential proposal. Does the definition of motion require the relativity of a reference object?
Kinda like a bird's flight. Do you measure its speed relative to the air around it, or by ground speed? My question was not if there IS another object, rather; is another object required in order to determine whether or not its moving.
I was attempting to help Gilbey narrow his scope so we can answer more intelligently in our opinions.
