Break it out. I have no issue admitting when I’m wrong. I just genuinely do not see what y’all are talking about in saying that faster than live travel, simply by existing, manages to violate the order of cause and effect.
I love it when sci-fi teaches us about real stuff. The problem is that when you mix instant and classical (non-instant) communication channels, you get situations where information time-travels, and the receiver gets information from the future. This breaks causality (present based on future events), and so nature rightfully abhors it.
The closest we’ve come to instant communication is the use of entangled particles, but we can’t make practical use of the phenomenon. Touch one such particle, and it’s pair instantly changes to the opposite state. The catch is that you can’t know when to observe the particle, nor can you know what the original state was, via the same mechanism. So you still need to use normal photons moving at slow-ass light-speed to communicate that meta-information, thereby undoing any attempt to exploit it.
Bonus points for starting with the point that forget warp, subspace communication breaks causality already, so you don’t even need to boldly go anywhere for any of it to be kinda busted.
If that’s a bit too dry you can search for a similar subject line, there are TONS of explanations like this one out there.
Anyway, none of it makes sense, it’s all for funsies anyway. Suspend disbelief, ye nerds, and enjoy your sci-fi.

I’ll help out. Here you go: https://www.askamathematician.com/2012/07/q-how-does-instantaneous-communication-violate-causality/

I’m falling apart right now because I’ve not been sleeping properly but I wll 100% look when I awake. Thank you <3
Ah… ok, wow, that’s a lot of relativity to explain from scratch for a non-physicist. There must be someone else…
Here, this one is a bit dense but it addresses Star Trek by name, so:
