What do you mean?

What’s “Forward Secrecy”?

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.

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

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

That doesn’t really tell me anything, haha

I don’t understand why people are downvoting this, but up, down, left, right all depend on your frame of reference.

Up in space is nowhere, but at the same time it is everywhere. Those are not physical concepts and they require necessarily a frame of reference to even make sense.
