Quantum communication

Yes, but cause and effect would still be in place, we just wouldn't know it.

Yeah, it's not just you who feels profoundly uncomfortable with the loss of causality. A number of physicists do too, and they're trying to come up with ideas for a causal physical system from which quantum behavior emerges naturally. It's all theoretical at this point, and plenty of other are just happy to accept that the quantum world just is what it is.

One thing for sure, this universe is strange, nothing you would have ever guessed at!

One way to look at it is that our brain has evolved and learned to intuit things in a causal world of large objects moving at moderate speeds. Since quantum and relativistic effects never enter into things, we have never been able to reach a point where they make intuitive sense to most of us.

The wonder to me is that, despite that, we've been able to figure out so many of the rules.
