The worst thing about interstellar travel: no internet

Gravity travels at c. The Alcubierre drive tried to use bubbles in spacetime to "bend the rules" in order to result in apparent >c velocities but recent simulations indicate the bubble becomes unstable when attempting to exceed c.

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.

Quantum entanglement is like ripping a photo in half, putting both halves in seperate envelopes and carrying them to opposite ends of the world.
As soon as you open your envelope, you instantly know which half of the photo is on the other side of the planet - Faster Than Light Information Transfer!

C is more than just the speed of light. It is the speed of Causality. No information can travel faster than C in a vacuum. Gravitational waves already reach us faster than the light from events that cause them (i.e. neutron star collisions) Because small particles slow down the light over long distances, as they absorb and then re-emit the photons.

The problem with information traveling ftl is, that you're very quickly running into paradoxes. So just by logic wanting to keep intact, I feel like ftl communication will be impossible

Never underestimate the bandwidth of a spaceship full of tapes hurtling through the cosmos.

Star Citizen has a ship like that. A cabin strapped onto the largest engine that wouldn't kill you, with data storage added almost like an afterthought.

Well, star citizen has a ship like that - it doesnt have any gameplay loops that make use of that though.

The futuristic version of never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.

Somebody just watched the Expanse for the first time and thinks it’s a neat new thing to explain to the Earthers

What exactly is subspace anyways?

imo by the time we have lightspeed ships we may have faster ways to send info, imagine back 2000 years ago and we tell people we can communicate faster than the speed of sound

Yeah we solved this problem in the 50s by including a clock signal in some form with the data. Most modern digital communications use it.

If nothing else, you discovered a way to gloss over the impossible thing in a bad scifi movie. "No it works because we added a timing signal!"

Tachyons.

heh, just noticed your username. Excellent 👌

"뭐?" = "What?" in Korean.
