Where am I challenging it?making that statement supports (1) as opposed to challenging it
All I have asked you to do is define your notion of "motion" - which I note you have singularly failed to do. Please have the decency to now define what you mean by "motion".
Then, once you have defined that - please indicate the reference frame that you are using.
This latter request in no way supports (1). You claim ALL objects are in motion.
My comment is that ALL MOTION is relative.
So please indicate where the commen that ALL MOTION IS RELATIVE supports your claim that ALL OBJECTS ARE IN MOTION.
You fail in your logic again, LG.
Now please just have the decency to answer the questions asked of you.
