Dude, North, South, East and West are not real either. Again, you need a frame of reference. Those are 100% arbitrary.

I can't tell if you're taking me seriously or not. 🤣

I am. "Halfway" is not a frame of reference. You need to arbitrarily define what up and down is. North and South is.

Why would it be arbitrary there? It's not arbitrary here.

I highly encourage you to Google this question. You don't seem to understand what a frame of reference is. At least not in this context.
