EVE Physics

Most of this stuff can be explained away with some creative technobullshite. Let's blame everything on the warp propulsion physics.

Suppose the the normal subluminal movement of your ship involves your warp drive modifying its effective mass. If you are moving at speed X due to having Y amount of kinetic energy and you turn on a device that discombobulates the Higgs field in such a way as to make you mass "seem" less, then you will be moving through space at a higher speed without having gained any real kinetic energy. This may be how such tiny ion thrusters are able to make your huge heavy ship accelerate at such fantastic rates. It also explains how ships are able to smash into each other at several kilometers per second without breaking anything: the real KE is negligible.

But apparently this technology has it limits. The faster you move relative to large nearby masses (planets, moons, asteroid fields, even the stellar nursery we seem to inhabit) the more difficult it becomes for your ship to decouple its mass from its momentum. As a result you are stuck in their reference frame. [*shrug* Sounds good enough]

And the max-speed of your ship is the speed at which the tiny push from you ion thrusters is balance out by drag. This drag may come from the ultra-ratified gases, dust, and plasmas in space. No space is truly empty. Or a better explanation is that there is an "etheric drag" from your ship's warp drive that exists whenever it's spooled up (even if not at full power). This happens due to gravitational interactions with the nearby celestial objects and a coupling of KE to and from them.

Combine this slow bleed of KE with the difficulty or breaking out of the stationary reference frame (increased difficulty cheating at higher relative speeds) and you have a situation that requires continuous thrust and has speed limit that you reach fairly quickly.

Anchoring can be the same technology, but in reverse. The effective mass is made so great that significant amounts of KE imparted to an object result in motion too small to be perceived. And any such KE is rapidly (and intentionally) coupled to the surrounding celestial bodies.

The airplane-like turning is a bit trickier to explain. Let's imagine that these effects are produced by coils within the ship (with a specific orientation to the hull and presumed direction of motion) that create a toroidal vortex (think smoke ring) of gravimetric energy around the ship. This swirling energy can be perturbed by asymmetric pulses from the drive coils to make it gradually shift its orientation, and with it the ship's orientation. And lets suppose that such movements slightly unbalance the gavimetric vortex, cause field-lines to breakout, and these reach out to push/pull on the surroundings in such a way that your ship's KE is redirected in a new direction (thus maintaining conservation of momentum). I'm sure the artsy people could produce some fantastic imagery of this.

The only thing that would need to be changed is to call MWDs "Microwarp Enhancers" since the micro-warp effect is always in use whenever you're flying any ship. And from here it's fairly straight forward to rewrite the ship movement code with modified Newtonian equations describing force, mass, acceleration, "mass modification coefficients", and "grav-interaction drag coefficients". Ta-da! Basically the same game-play (I foresee subtle differences) accomplished using quasi-realistic physics.

Wow, When such techno BS flows this easily it's a sign you've watch waaayyyy too much Star Trek. Lol Maybe CCP's lore folk could whack their seal of approval on this, or use some of these ideas when writing the official cannon.

If you value your clone step away from the red shirt..

and yes, there really is no point talking about real physics in a game like Eve. The limitations of the code and servers dictate what's possible or not regarding this, not actual physics! Also the techno-bullshit is strong in this one...

Guys, you're all missing the point of this post. They are just ideas. We can all speculate if it is possible/better, whatever. The idea was to post my concerns in a way that they could maybe be visible to developers. If they like it, they'll implement the ideas, if they don't like them, then they wont.

And for the ones that reject all an every idea that doesn't conform with you views of the game: Who hurt you? Are you ok? Do you need a hug? I like eve because its a really immersive sandbox, so immersive in fact, that some people really take it too serious. Guys, chill. It's just a game and I'm just giving my opinion. Don't be dismissive. Just dream of the possibilities :)

Finally, I don't know if you're up to date with eve development, but they have quite a large amount of resources invested in physical based rendering, new ship models, new structures, and basically a lot of eye candy. So I can see them investing resources in more realistic flight animations and movement. (The tecnomumble was all and good 10 years ago. Now, not so much. I think they can implement some of these changes if they want :D )

Dude can you hear yourself?

"convinced you know nothing of which you speak of" ... really? Do you talk like this? Are you trolling me?

What do you mean I "know nothing of which I speak"? What is it that I "don't know about"? My own opinions about what I wish EVE was?

Nothing I've said was false. Star Citizen is making MILLIONS because people want to play it, desperately. That is a fact. I BLATANTLY said I don't care about how the two games compare, the FACT is that people want a MODERN SPACE GAME. THERE IS A DEMAND FOR IT. You're trolling right?

Recoding EVE might has well be making the whole game from square one


I just said thats what I would wish for. And you keep trying to argue that recoding all of EVE is impossible/bad idea because it would take recoding all of EVE. Are you trolling me???

no owner of a MMO would do that thanks to the amount of time and money that already went into making in the first place. Common sense dictates to patch the old code rather than remake it.


No actually, common sense dictates this is how a game will eventually die, because it becomes completely outdated and surpassed by everything else. I don't know about everyone else, but I have always hoped EVE would update and evolve, not stay the same old game 20 years from now, trying to hold on by being this "cool", "retro" game that people still play ironically and just for the nerd-factor of the interesting stats and game mechanics.

Currently... your Space Engineers and your Elite:Dangerous are your generic, probably failed, space games. Star Citizen is shooting for the gold, but might fail as well, maybe it's ahead of it's time. Or it might be as INSANELY awesome as it's claiming to be... but no matter what, eventually technology will reach a point where even the BAD, failed, lamest Space games that come out will be better than EVE in every way... and the good ones??? They will be make EVE look like Asteroids.

CCP's stated intent is for EVE Online to go on "forever". There are certain aspects of its current physics model that I don't see remaining "forever" without soon becoming quaint and dated. There are some things that were quaint and dated five years ago.

Sooner or later there is bound to be a total overhaul of the flying-in-space physics. It might not happen for a rather long time. But if CCP is even marginally successful in their highly ambitious mission of "forever" then it will happen eventually (but not necessarily the OP's vision).


^ this guy gets it, but unfortunately I don't see CCP's actions reflecting those sentiments. I think CCP is stringing us along, with new gimmicks and barely balancing things, to collect subscriptions as long as possible, before EVE just dies. Based on the way they run and update this game, I don't see any indication that they care about the future of it, or want to ever bring it into the modern age with a new game engine.

Guys like Madd Adda, probably 80% of the playerbase, are all so averse to change that I don't think EVE will ever become a modern game. Most likely CCP will go under and EVE will die completely, or maybe they'll stay up and the game will slowly die as less and less people play, years and years from now, until CCP becomes a company of a few dozen people, barely able to support an MMO, let alone update it. And it will just be this weird old space game, with laughable basic physics and barely fun gameplay, just some cool space ship stats to play with, and LOL at the cool "oldness" of it.

I share that sentiment. Too much eye candy, not enough mechanic. But I'm realistic about how much can be changed without it breaking EVERYTHING else. You can't just add hybrid turrets and stasis webbers to KSP and expect to get a playable game. Every single aspect of EVE's combat system is based in limited velocities and acceleration. Space needs to remain gooey. The point of my techno-BS post was to find a middle ground where everything "works" and in a way that's somehow rationalizable. Indeed, there are aspects of the physics could be upgraded without it wrecking the gameplay. Station sizes, tighter collision meshes, ship orientation and rotational inertia, F=ma, the inelastic collision math, etc.

EDIT: And cargo mass affecting acceleration. It has always bothered me that empty freighters cannot accelerate to warp faster than fully loaded ones.

forget it Reina, you can't be reasoned with. I'm not averse to change, just aware of the price tag attached to it. EVE was a modern game in its time and maybe it will again, but on its own time NOT on your time schedule. I am aware that EVE's physics don't match up with reality, but I let that stop be from enjoying the game.

LoL I tear apart everything you say with logic and facts...

What reason are you trying to enlighten me with? I'm not denying the things you're saying... yes building a new game from scratch would be difficult and expensive and time consuming...

And I point out all the brand-new, from scratch games that CCP is trying to build over the years, instead of updating their space-ship engine... and you, what? Have nothing to say to that because it's true.

I give you reasons why I wish EVE would be updated, and you just cry "NO!" "Impossible!" "WHY would you even want it???" "Nobody else wants it!"

Yea well... Star Citizen's hundred million dollars in crowd funding stands to disagree with you.

"tear apart everything you say" more like you adhere to your logic like a christian to the bible. nothing I say will move you and nothing you say will alter my thinking, so i'm just backing away from this before we both get banned.

The point i'm trying to make is that CCP is a company that is in charge of its own finances and its own IP. Complaining about them making an entirely new game set within the EVE universe is futile at this conjuncture. Continuing to compare EVE to Star Citizen makes me wonder why even bother remain here. It's nice they got 100 million from a crowdfunding campaign, but EVE didn't do that, so kindly deal with it. There is one more reason: My computer is pathetically old and i can't afford another for quite sometime. Updating the graphics of the game might make it unplayable to me.

I have a feeling that the changes to deployment method and gradual changes in game mechanics are a means to pull out chunks of functionality and improve them. Once the remaining core code gets small enough they can replace it entirely.

By your logic maybe we should revert the EVE graphics back to what they were in 2003, right?

I mean there's lots of people probably still on old Dell towers running XP and onboard video cards... and they played EVE in 2004 so why should EVE's graphics be updated?? That might render the game unplayable for them!

You really should duck out... you can't make a good point to save your life.

Kindly deal with it?? Dude I AM dealing with it. I play the game...

and then I come to F&I to talk about what I wish the game would be someday...

YOU on the other hand... come to F&I to cry "no no no no no" at visionary ideas to improve our beloved game. What is your purpose here? What are you trying to convince me of?

I'm trying to convince you that EVE would be AWESOME if it was rebuilt with a new, better game engine. As long as you keep responding with blanket "NO THAT'S DUMB" statements, I'll keep trying to change your mind.

I deal with legacy coding regularly, and it is a PITA.
Newer coding is often modular parts working together, and is much easier to patch and modify the bits you need to change.

I hope this is the way CCP is going. Change is good.

My dream update would be real orbits and rotations in solar systems. Every day that planet, moon and station would have moved slightly (in their orbits/periods), Asteroid belts would physically be in motion all the time (you would have to track them like a ship to mine them). That 'old' suggestion of adding comets would be a nice perk too.

Today I learned that ships in eve turn like large flat grasslands and display animations when they malfunction or are broken into pieces.

CCP has already said that the physics model is staying because of gameplay reasons. If you want Newtonian physics, go play Elite: Dangerous and turn Flight Assist off. It's ... an experience all its own, trust me.

EDIT: In EVE, an unfitted interceptor at maximum warp speed without implants is traveling at approximately 1.2 billion km/s, or roughly 4x the speed of light. By way of tangentially related trivia, 1AU/sec is approximately 0.5c.

1AU/s=500c, rounded. It takes sunlight about 8m 19s to reach earth.

Collisions. Bouncy ships?! Come on CCP! Ships should be able to crash into one another! (I know I’m asking for too much here).

PROPOSED SOLUTION: With basic physics and a simple function that converted momentum to damage you could easily have collisions. You can make it so that a frigate crashes a big ship’s shield like a mosquito in a windshield, but a Titan ramming into another would be like a catastrophic event.
GAME MECHANICS CONSEQUENCES: You could ram titans and supercaps into one another! Possibility of adding ship formations and more useful divisions between squadrons and wings since now you have to be aware of where you are related to the rest of the ships. So, you would have your FC commanding the whole fleet calling targets and warps and everything, while the WCs would be responsible for moving the actual wings keeping formation. No more “all ships anchor to the FC crap” now anchor would mean keep formation with the WC with some kind of automatic system like in Age of Empires. The WC would be the one moving the fleet while the FC calls for targets. This means that the only job of regular line members would have is to target and shoot, so… basically the same as now. Also, to prevent collisions on dock/undock you make a (visible in the UI) radius around each proper scaled station where the docking system takes control of your ship and moves it to one of the docking ports. For gameplay’s sake you can’t take damage when you are inside this radius. On undock the same system takes you out of the automatic docking radius.
ADVANTAGES: No more immersion-breaking bouncy ships. No more “swarm” of ships just moving chaotically, this would mean the space battles would look 1000% better than the crappy mess they are now. No more stations spewing stacked ships.



This has been asked for, repeatedly, for the past decade or more. CCP isn't interested. They LIKE IT that small ships can intentionally bounce big ones in complete defiance of all known laws of physics without taking any damage or even raising a criminal behavior flag. They LIKE IT that npc corp characters can use this mechanism to aid ganking in high sec by preventing that valuable target from warping.

It would be fairly easy, imho, to create a lockout zone within 5km of stations and gates in which the docking/undocking mechanism takes over and exempts collisions between ships under its control but leaves alone collisions between a ship not under its control and all others. [same applies to other objects at which a ship can be docked or undocked, perhaps with lesser radius of action]

obviously, the proper physics is: [imho]

a. collisions create damage proportional to the relative momentum of the ships involved [mass times (1 * velocity/c)]

b. a collision that does NOT go beyond shield damage to a ship does NOT change its course

c. a collision that does go beyond shield damage results in criminal flag and CONCORD intervention if in high sec

d. if a collision results in sufficient damage to alpha the ship, it is instantly destroyed and killmail results as usual


This wouldn't change null sec much at all except that your Daredevil couldn't successfully bump a carrier -- it would self-destruct.


BUT -- CCP continues to listen to the ganker community and support this bogus physics. We have to assume that, in CCP's opinion, gankers pay in enough real life cash each month that they NEED this revenue (or they buy PLEX from others who do pay in RL cash).


Just because I think that's complete BS doesn't mean that Iceland is going to change anything.

The technology is only part of the problem. I have no doubt that the servers currently running could easily support a modern multi-threaded code base. However Eve is a currenrtly living and evolving Live system, thus any changes must be iterative and relatively small in nature to allow for easy backout and/or repair in the case of failure to apply.

I get the feelingthat this is what's going on right now with the 6 weekly changes and the download on demand launcher. Once that's all working reliably they can strip out/replace bits of the underlying architecture in nicely manageable chunks until the remaining legacy code is small enough to replace in one go.
