How about we just put everyone on the ground, attach bipedal legs to our ships and run around controlling pieces of land?

Oh wait, that game sucks.

To follow this idea them, what would stop them from using some kind of message pattern ?

If you think about TCP/IP packets, a header describes the message, but it's done in situ and, crucially, its done at the same speed as the packet.

In a quantum entangled system, perhaps you'd send a message specific to your pair that could be recognised in its own state or inverted; You'd then follow with a checksum that proves the polarity of the opposite pair, so if you get 01010101 you know that the other one is in a clockwise state, and 10101010 is anti-clockwise.

Holy ... did we just invent TCP/QP ? (Quantum protocol)

So what you are saying is that if I apply 1.21 gigawatts through my flux capacitor, normally I can travel thtough time (after hitting 80 mph of course!) But what if I apply 2.12 gigawatts through the same flux capacitor while travelling at half the speed of light AS IT EXIST IN A WARP TUNNEL DURING WARP?.............

I will ponder this vexing question for weeks now...

I know there is an answer somewhere!

This would work if at the transmitting end you could choose the state of your entangled particle to be 1 or 0, but the problem is you can't do that. When an entangled state is created the spin of the particle is random, which means the other member of the entangled pair also has random spin -- so no fancy checksumming or parity system will work. The only decision you get to make is when to measure the state (and whether or not you measured it is not something the other person can determine without first sending their results for comparison).

Here's a math analogy: Think of two people sitting in different galaxies, both with random number generators with the same seed. One of the two generators has a random pattern ("the message") XORed with its output. Both people can both generate random numbers whenever they want, but can't examine the state of the generator or otherwise communicate. Is it possible for one of the two people to determine the message? Clearly it's not possible unless you can compare the output of the two generators -- which means sending the output of one of them slower than light, and this defeats the whole purpose of your messaging system.

Oh really? You are comparing EvE to Evochron Mercenary?

Just a guess here.... but do 50,000 plus people play Evochron Mercenary at the same time on ONE SERVER?

The ISD has it 100% right... EvE is made like it is so 50,000 live internet connections can exists on the same server.... don't like the "sacrifices" in "realism" that have to be made to play a space MMO this large... go play a different space MMO that is this large..... Oh wait, that's right... there ISN'T another one....

I see what you're getting at; I guess it would depend what happens to your pair after you first entangle them and then induce a change in one's state too. After all, there is a point where they can communicate at sublight speed, and that's when they're made and tangled.

This, of course, relies on us inventing a system that allows us to induce and read a change, without breaking the existing entangled state; which I'm led to believe is also very hard at the moment.

Hmm food for thought, it's a fascinating topic!

More on this tomorrow I think, it's very very late here :)

But, regarding the other point - I know I'm being a pedant, but it depends what you define as being information?
After-all, the experiments prove that we know the state of one of the pairs ... and if we can't actually extract the specific (although i'd bet we'd just be saying that any of one rotation is 1, and any of the other is 0) we have the information that the pair was changed by effecting the first.

If we didn't know that, we wouldn't know that the experiments work!


You're right -- I should be more specific (I'm a massive pedant too!). Clearly QUANTUM information is transferred between the pair, but crucially CAUSAL classical information is never transferred faster than the speed of light.

The reason for this: Measure one particle's state and you gain some information, but until you know what the state of the other particle was measured to be your information is useless. The only way to find out what the state of the other particle was is to have the information about its state transmitted classically.. slower than light.

The tl;dr is as before, entanglement can't be used to send useful (causal) information faster than the speed of light (as far as our current understand goes).


This.

Other things can travel faster than c without transmitting information too. Example: Consider an observer surrounded by a massive sphere 3 light seconds away from them. They point a laser at the wall and spin it. The 'dot' on the wall moves much faster than c but transmits no information.

The other thing is - once two events occur outside of each other's light cones (i.e. light from one hasn't reached the other), relativity tells us that we cannot discern which of them happened first or if they were simultanous. What is 'instantaneous communication' to one observer is 'non-instant FTL communication' to another and 'sending a message backward in time' to an observer in a different reference frame. (I'm actually playing upon this in a fictional writing project at the moment)


Of course this assumes that relativity is correct. It is a theory after all (albeit one that has been very effective in making predictions including some very counterintuitive ones)


Again, however - let's suspend disbelief in the interest of game design. Instant communication makes the game more entertaining than it otherwise would be.

Relativity means that you always train at the same rate - it's other people who train faster due to lower gravity or slower due to high velocity.

Surely one of the biggest atrocities against relativistic physics in this game is the instant communication.

I can be in a station 10AU (80 light minutes) from an asteroid belt and get instant intel from the belt that there's three untanked Hulks there from a scout and assemble a fleet to obliterate them well before the message should have even travelled 1AU.



Only if You presume that communication happens via radio waves, which indeed move at the speed of light.

but as far as I understand it capsuleers use something akin to quantum entanglement for communication.

To be fair, this isn't true. Railguns, cruise missiles I believe, and some others can push almost or more than 400km.
Raven, rigs, cruise missiles: 394.9 KM
Eagle, 250mm rails, spike, 4 tracking comps, 276km max range
Rokh, 425mm rails, spike, 2 tracking comps, rigs, 413km Max range
Apocalypse, Tachyons, Aurora, Rigs, 2 tracking comps, 347km max range

So no, weapon ranges are not 250km at most, TARGETING ranges caps out at 249km.

It's still lame. I want to equip cruise missiles with warp drives and shoot them across the system.

Those imaginary ships we're supposed to commandeer are nothing less than technological marvels and we can't even get accurate firing solutions at not even more than a mere quarter of a kilometre.

EDIT: That ofc was nonsense it's supposed to say Megametre, a.k.a. 1000km.

With what shuch ships should be able to do 250km actually should be considered ultra close quarters brawling range.

The range of capital ship class weapon systems should be measured in AU, not some pansy little kilometres.

and that's almost the only thing that's bugging me in EVE.

The other thing would be that, anything bigger than a Battlecruiser is shooting stuff at other stuff that would be considered at least a city buster in our days, and still they're really really tiny... torpedoes for example have a size of 0.1m^3 it's small enough to fit into my hand, make 'em as big as real torpedoes and the can destroy stars or have a flight time long enough to be shot into adjacent solar systems?

And yet the launch bays for them are as big as my house. o_O

What did they build into those launchers? A shopping mall? can't be an ammo depot since all the ammo is in my cargo hold and the 20 rounds that fit into my torp launcher could also be stored on the desk of my first mate Joe Anybody who's name I don't even know because he's not a capsuleer and will be forgotten once I vent the atmosphere to dry clean my ships interior.

I believe the record number of people in one 200km chunk of space is around 2000, actually.

EvE is a series of interconnected instances. A very impressive method, mind you, but it's still very, very instanced.
