No shit.
It might become like the days of sail. The fastest mode of communication might actually be the speed of ships. In order to get a message between earth and alpha centauri you might have to actually build messenger ships.
You might have to build small automated FTL capable ships with massive data storage capacity and then download all of the data you need to send and then set the ship off on its way.
Never underestimate the bandwidth of a spaceship full of tapes hurtling through the cosmos.
The futuristic version of never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.
Uh, no shit? That’s how light works once you’re able to travel at relativistic speeds - communication over interstellar distances using light is going to take ages.
Even within our own solar system interplanetary travel will have significant communication time delays.
Edit: also, we already know that matter and light can’t exceed c, but I wouldn’t be surprised if we discover that other forces (gravitation, or another that we haven’t understood yet) can transmit information at speeds >c. I wouldn’t be surprised if we turned to quantum entanglement for instantaneous communication over extreme distances either.
My first thought was ‘no shit’ as well. There’s a horrible heartbreaking anime about that… Voices of a Distant Star.
other forces … can transmit information at speeds >c
I sadly disagree. Even if we figure out a way to instantaneously transport ourselves across the universe, there will be some shitty clause in fine-print that says we can’t go back, or it took 0 time for us but 1 billion years for everything else.

or it took 0 time for us but 1 billion years for everything else.
That’s just time travel with extra steps!
It literally is time travel.
We are all currently time-traveling at a ratio of (edit: roughly) 1:1
Quantum Entanglement
Why dont they just get an astropath?
Because they’ve already got ansible.
This is why Jesus invented ‘two cans and a piece of string’.
Dammit, I’m not even a trained physicist but I still have to do all the thinking around here.
Jesus Christ, why’d this get so downvoted? Do people not get sarcasm?
I was actually wondering what would happen if you would just put a big rod of metal in 0 g and pushed it? If one end shifts 1 cm, how long would it take for the other end to also shift? Wouldn’t that be instant? Well, apparently the signal would travel at the speed of sound. Which is weird, right? It makes sense but it’s still weird.
