Subspace is the answer of course!
Okay just a hot take here, but I don’t think this is the biggest barrier to interstellar travel.
The worst thing about interstellar travel: no internet
Buddy can you imagine all the new alien pron in the new system though?
Also, I don’t think this is anything particularly new. It’s pretty logical of you think about it for a few minutes.
I mean space is pretty empty yea but I feel like it would be a pain in the ass to prevent a ship travelling at light speed from bumping into small to mid sized space debris. On the other hand, I am imagining with this much drive on energy techs we will be at some point able to come up with a solution to the energy requirement to power such a vessel.
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.
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.
Then we need the Tim (Allen) Taylor solution.
Moar Power! Uhh uhh uhh uhh uhh

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!For a variety of reasons, no information is actually transferred. Quantum entanglement can not be used to get around the limits imposed by relativity.
That’s what I was trying to illustrate.
So it’s not like: when I affect the hue (some attribute) of my half, the other half will change too? That has always been my understanding of it
No, measuring one particle collapses the entanglement and they no longer affect each other. It is a one time thing. You can’t modify them after they have been observed.
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.

Oh, you already know about it. No one else should bother reading then.
Why is this even an article? It’s obvious.
Somebody just watched the Expanse for the first time and thinks it’s a neat new thing to explain to the Earthers
Is it weird that I’ve only ever read the books? I didn’t even know there was a show until recently. Is it any good?
i knew the expanse would pop up somewhere in the comments! been working my way through the books and it’s great!
Also Passengers, starring Chris Pratt, has a mention of this too.
No shit.
Who would have thought that Doppler could apply to communication equipment, too! Shocking!
Next they are going to tell us that messages might take some time due to c!
Have they never watched Star Trek, subspace relays people.
What exactly is subspace anyways?
It’s a different part of the universe, separate from normal space where things like baryonic matter exists. In subspace certain of our universe’s fundamental rules as seen in normal space don’t apply or constants are different.
How much of this is based on reality and how much is based on Star Trek wanting a mechanism to be able to communicate between star fleet and the Enterprise?
I think entirely Star Trek on this one. Although, if we ever want to move* faster than light, it’ll almost certainly require a science or an understanding of nature which we don’t even have theoretical concepts of in 2023.
Space is like a rainbow, subspace is equal to ultraviolet and hyperspace is infrared. At least inmy head cannon.
Duh.
how could that be surprising??
_ /\ _
It’s not a surprise, it’s just a concern being presented because it’s not a thought for the average person.
isn’t developing light speed spacecrafts a far more direct concern?
why even concern about communications when travelling such distances isn’t even possible.
I don’t see the point of the article.
trash site
Jerry Pournelle’s “CoDominium” books work like this. The ships are FTL, but can only use the FTL drive at a certain point to leave a system. There isn’t a way to send messages faster than light, other than a ship. There is mention of “message sloops” which are small ships with high acceleration wich can move from the jump point to the inner system faster than one of the battleships.
Subspace interference.

Well since we are talking about the time when light speed is possible maybe we have invented superluminal communication
