I don't understand something about Stellaris's hyperspace tech

[Geodynamis]

Being as it facilitates FTL telecommunications and transportation, how does it avoid breaking causality in a galaxy thousands of light-years across?

e.g. Sol and Alpha Centuri are approximately 4 light years apart, which means a UNE colony ship on Alpha Centauri III had landed sometime before the order to build said colony ship was issued to Sol Starbase shipyard (from the viewpoint of the Alpha Centauri system). Without an absolute frame of reference, how do objects in different star systems know when "now" is and not accidentally go back in time?

 

[RabbaDooDabba]

Easy answer, time dilation is not part of the game's mechanics.
Stellaris is just a game and not an acurate reflection of reality.

It's because of the Transmoglifyer, a sufficient level of Moglification is achieved by shooting Charged Kroutons at stabilized molecular chains of Googliguzonium.

Without an absolute frame of reference

There are several ways to figure out the "absolute time" (edit: at least in reference to other places) when you know where you are. You can look at the spin positions of neutron stars, every single one of them has a specific rotation time, if you know hundreds of them you get the exact time by comparing their relative difference until their next "ping". Of course you have to take your position in space into account

Other way would to look at the temperature of the background radiation, but this requires requires really exact instruments.

But this is not the same as the question in your topic, here is a video by Neil Tyson about this:

In short, if wormholes do exist then our understanding of causality and gravity is at least incomplete

 

[WalimWTo]

It's simple (and physically "not impossible"): hyperplanes.

They exists even when we don’t use them and forms shortcuts, so Sol and Alpha Centauri are not 4 light years away but one day (or something like that) - and always have been. One synchronization route is enough.
Its valid even with different FTL methods, as long as you are visiting only systems in hyperplane web.

i'm advocate of the fact that if you are not in africa and you hear hoofs , you say horse not zebra .

timetravel doesn't exist in our reality , as such you simply have a distance of 1 sec from the starsystem the moment the travel was made . the only thing that will have to "cach up" is light , that will have to show the starsystem pre-occupation for evry other system for the time light will take to show it.


as a side note, the rule of casuality doesn't realy break for FTL travel, as there is always a reason for it to happen .the fact that we considerate light or our reality as an absolute and only doesn't mean they are .

 

[Olterin]

We-ell... first off, this is a game. Where somehow every species lives in the year 2200 by their calendar. FTL possibly breaking causality isn't the biggest worry...

Second - for FTL to allow time travel, you still need two frames of reference moving relative to each other. As far as that goes, look at your galaxy map, all the systems are stationary on a 200-year-timespan. There, problem solved

That's not how time works.

If light takes 4 years to travel from Sol to Aplha Centauri thenit would take 4 years to SEE what happened on Sol if you had a telescope strong enough to view the system.The event it self would still have happened 4 years ago.Being able to see something does not mean that it is happening at the same time just like hearing something doesn't mean that the sound was caused at the same moment.

There's no universal time. Being able to see something happen is being causally connected to it.
This guy explains it better than I could

i .... will need to watch the video when i get time. i don't know how what he is basing things , but we have already hint at things moving faster than light at a quantum level, "instant travel" is something that seems to happen alot , and there is no "time travel" in it or casuality breaking .


there is no proff that traveling faster than light will make you travel time, as we don't realy know if time is something that "travel" . we can observe that energy alter time and time act on anything and evrything , at least that travel slower than light for now.

so in my opinion is better to think that traveling faster than light is simply traveling faster than light , and so you can see your "past" by simply outspeeding light . but you don't actualy travel time, you simply see the light that was reflected by your body when you started.

Occam's Razor, put simply, states: “the simplest solution is almost always the best.”

General relativity, he's basing it on modern physics. This is normal university level physics. The obvious but boring answer is that faster than light travel is impossible, or if it is we don't have any physics that would allow for it. And likewise we don't have any physics to understand the breaking of causality. Nor do we have any reason to think it's possible. The only examples of faster than light travel are cosmic expansion (distant galaxies receding faster than light), black holes and cosmic inflation (big bang), the problem with all of these is that none of them allow travel from point A to B, only separation of point A and B. IE it's not possible to travel to anywhere using FTL.

If you want a math-y answer for why FTL is time travel the here you go

How anything faster than speed of light travel back in time?

I know about this theory but I cannot get the picture that how moving faster than light even 100.01% of light-speed would make universe run backward.

physics.stackexchange.com

If by "things moving faster than light at a quantum level, "instant travel" is something that seems to happen alot" you're talking about quantum entanglement AKA "spooky action at a distance" (as Einstein put it) then that's not actually FTL communication, it's a byproduct of the fact that quantum entangled particles will have opposing or complimentary properties, so if you know one has spin up the other must have spin down. Your observation of the spin does not cause spin up in one and down in the other, you observe it.

Quantum entanglement faster than speed of light?

Recently I was watching a video on quantum computing where the narrators describe that quantum entanglement information travels faster than light! Is it really possible for anything to move faster ...

PBS Spacetime also explains it (this time using the standard model)

 

[Scyobi_Empire]

Well, there is this thing called an 'Engine' it handles the barebones of the universe. Gods then add stuff onto it like the recently discovered Spies.

We live in a simulation, don't listen to them you know it to be true!

The Stellaris universe does feature an absolute frame of reference: the hyperspace network. Gateways could bypass this but they're also synced to hyperspace time. All stable wormholes are also synced to hyperspace time. Presumably all unsynced wormholes destabilise or are destabilised by forces unknown (after spitting minerals at you for a decade). If the stars in stellaris moved or someone invented some form of warp drive we could be in trouble but we all know what happens to empires who invent warp drive.

well, before even starting to talk about the system he created... you should know that math is a extraordinary language , but thats it , it is a language , not science .

now, the system he created say nothing , he still follow the illusion that for some reason there is timetravel because there is an observer that SEE something happening before something else happen .

take this as example, i'm at a distance with a bigarrow telling you to go left. then i travel at ftl(EDIT i wrote lightspeed)at a shorter distance with a new arrow telling you i was wrong, and to go right .



since light will always go at lightspeed ( this is one of the reason we are convinced there is nothing that go FTL ) you will always see first the arrow telling you i was wrong and to go right BEFORE i'm telling you to go left. SO FOR YOU i timetraveled , NOT BECAUSE I ACTUALY timetraveled but because you can only observe the light reflected on me after i moved before the light before i moved.

but for me , i didn't timetravel . i can see me behind me with the left arrow , but it is nothing but a immage , not reality .

this is a concept that is realy hard to explain to ppl convinced that what they see is what is reality , LIGHT IS A GREAT way to observe the world, but once you assume FTL is real , light become the BIGGEST ANTAGONIST in your understanding of reality .

its like using sound as a way to see the world when you travel faster then the sound .
edit: you can hear yourself if you travel faster than sound and stop AFTER you reach your destination .

well, we can call it however you want . sound "travel" by vibration and has a speed, light travel on waves and has a speed. this is simply another speed that we don't want to recognize as FTL because we still think there is nothing FTL . this is why they call it something else as " entangled particles" and not a speed .

If I show you two cards, a king of hearts and a queen of hearts, I put both in identical bags and shuffle the bags such that you can't tell which is which. I then keep one and you keep one. Neither of us know which we have. Then I travel to Mars and I'm 20 light minutes away from you. You open your bag and see that you in fact have the queen of hearts, you know that I therefore must have king of hearts. The information has traveled instantly. But it's not really FTL communication. That's what quantum entanglement is.

Since nobody else points out the obvious answer:
Perhaps the Worm loves us, and perhaps we could love the Worm.

Thats a very simple to the bone explenation . you forgot to add, that once you watch your card that change and so does the other one , at the same time invery different space, meaning that they TIMETRAVEL OR they can exchange information FTL .

i would have used our immagination . we can immagine to go FTL . thats doesn't count as speed for how we define things , or yes?

we attribuite to sound speed, we attribuite to light speed, we attribuite to wind a speed. all those are very different way of having a "speed" .

the solution that there is timetravel , is quite romantic , but is jumping to zebra before considering horses.
at best there is lost-casuality , where the information for the cause of a event is lost . thats the closest thing to time-travel , and is theoricaly achived by blackholes.

That we use light to see has nothing to do with it. C is the speed of a massless particle and light is the massless particle we're most familiar with so we call it the speed of light. But it's not "seeing" things that's the issue, it's how the behaviour of matter with mass when approaching C interacts with objects traveling faster than light.

Here's an old but good walkthrough:

Why FTL implies time travel (tachyon pistols)

Of course the simplest explanation is that stellaris is a non relativistic universe. You can go as fast as you like with hitting relativistic effects and the hyperlanes are just very efficient modes of travel. Light travels instantaneously and FTL stands for "Faster Than Lasers", which are surprisingly slow and dodgeable.
