(I should probably have said "causal loops" here - loops inconsistent 
with causality.)

Well, there are - but that's not what I was  talking about. I'm not 
competent to judge how serious they are.

It is just my understanding that the interpretation is still debated by 
some. Specifically, what does causality mean in a Minkowski space?

And my point was that if you still believe in causality, you have a 
partial order. Well, at least a directed graph. If you believe causal 
loops are impossible, you have  a partial order. And all partial orders 
can be embedded in (possibly many) total orders.

By the way, I am not a serious scientist, and I don't deny the 
possibility of space-like intervals. I am 100% on board with the idea 
that there is no absolute time.  I am not a ROD (Relativity Orthodoxy 
Doubter).  I am a QUOD (Quantum Orthodoxy Doubter).  I made a mistake in 
mentioning QUOD, when Terje was only referring to relativity.
