ED does not do what Newton's Laws say......
- Thread starter Cmdr BrinBrown
- Start date
to an outside observer space ship earth spins at 1000 mph whilst maintaining a rel velocity of 67000 mph
but we feel nothing but 1g which we barely take notice of
do you know what its like to fly through space the truth is you have never known otherwise

ED's flight model is one of the best with FA off, imho. I've played several of the recent space "sims" listed previously especially X4, Spacebourne2 and Everspace2. One game I did not see mentioned was Evochron.
It was my favorite space game until ED came out. I liked its flight model better than I-Wars or any other space games from those early years. Evochron was great in many ways; lacking in others but still one of my favorite.
I can attest to the difficulty chasing a ship down in space using Newt Flight was with Pioneer. I never caught a ship that had even no advantage in speed but after turning and burning to match their vector, I was way behind ... gave up after a ridiculous amount of time ... I just knew I could catch that thing. live and learn
edit: Oh, by the way has anybody played Flight of Nova ? Its a pretty game
Have a nice day

Oww, my ears! Is that the PC version? That kind of proves my point though. For the combat to happen, both parties have to 'agree' by going to a 'relative' mode. If one party does not play, what are you back to? Zipping past each other at significant fractions of C.
Ooh err, we're going there are we?
Newton's Laws of motion are almost entirely wrong, but they are close enough to what we actually observe that they can be uses to predict behavior within a certain acceptable parameter. Their advantage is that they are simple to apply, their disadvantage is that once you get outside of a certain level of application they start causing issues, this is why the GPS system has to be adjusted for relativistic effects or it quickly loses accuracy. Under Newton's Laws this wouldn't be necessary. They are good enough for most uses is about the best that can be said.

swirly thing alert!
spacetime and quantum gravity
and as for dark matter well erm it's dark but i bet that swirls too so hats off fo kepler
the answer to all of this i am sure is just at the top of my head but i just cant see it

GLFrontier, which is based on the Atari ST version of the game.
Did anyone read EE Doc Smith Lensman series?
They had an interesting solution to jousting in space which was the ability to engage an ‘inertia’ drive.
So full Newtonian but when near enough to another space vehicle, you could pull your vessels to share the same relative speed so that then it would be possible to do the pew pew like planes and not joust.

This is not my idea, it is physics.
I'm talking about the torque that is required to generate angular momentum, the faster that you are traveling in a straight line, the more thrust is required to deviate from that line. Clearly the main thrusters have far more thrust than any of the boosters, so beyond a calculable velocity the directional thrusters would no longer have any effect. Currently in game the ships nav computer slows the ship when you reach a set velocity or speed, no idea which though, and so If you want to remove this in game, you could do so with engineering and applying what would most likely be illegal firmware patch to remove the limiter that has been placed by the ships constructor on the thrusters.
Laws and rules are made to be broken, that is how science ~ the rule book ~ evolves using the method to insure a lucid rational.
Are you familiar with the eccentric orbit of mercury, the orbit that does not fit the newtonian algorithms? Rather fitting, as Mercury is often caste in lore as the cheeky devil, bending or modifying the rules!
Addendum:
The crossover between law and lore is rather more fused since Godels incompleteness theory blew up Bertrand Russels teapot having located it in orbit by a process of logical construction, rather than the laboured process of deduction. Have you read about or come across constructor theory? If not you might consider doing so, it is capable of some considerable feats yet is completely different from anything in the current rule book.

You make a good point, perhaps even some DNA test that reveals its age, I think there could be some interesting uses for DNA after long distance space travel, that the aging process in organic compounds could have some markers that differentiate it from local DNA, and this provide some sort of scale!
But also, what might it do to the Brandy! The mind shudders like a fully laden type 9 under flight assist!
Think you are going at cross purposes here, the direction in which you are traveling will be difficult to change rapidly, but the direction you are pointing is trivially easy to change, therefore this;
Is entirely correct, you can point in any direction you want with very little effort,. Also regarding deviating from the straight line, no, if you want to move 2 meters to the left it requires the same force stationary as it does while moving, it's just that the change in location will be expressed as a curve and not a straight line.
These two things are both correct at the same time so this doesn't apply, rotate away all you want;
It will take the same amount of force to rotate the ship regardless of whether you are stationary or moving extremely fast in a particular direction. Of course rotating the ship will change the vectors of force being applied by the main thrusters thus changing your vector. In fact this is one of the principals of changing the direction of an asteroid that is in collision course with the earth, the further away you apply force the less you need to apply to get the same effect at the end point.
In fact in Einsteinian Physics, as opposed to Newtonian the amount of force required to change direction is different, mass increases with velocity so the faster you move the more force is required to change direction, but in Newtonian it's not the same because Newtonian mechanics doesn't take into account relativistic effects.

For a generally realistic combination of current-to-plausible-future technology and 3-law Newtonian mechanics then Kerbal Space Program (the original) is very good. There are some concessions made to gameplay and available computing power (e.g. the effects of gravity are restricted to nested two-body problems) but it's sufficiently well-simulated to get the idea across.
At lower realism (comparable or greater than ED) there are quite a few games (going back to old 2-D classics like Lunar Lander or Thrust on the various 8-bit platforms) which implement some level of "there's no drag in a vacuum" while allowing somewhat "traditional" space combat.
I was thinking too that DNA would have different markers depending upon where it is aged, but that is highly speculative, quite right that the back ground radiation in any one point would be very different, and leave a trace for us to examine in relation to our time.
Well spotted! I do tend towards thought that is in relativistic terms; Thank you for the insight.

DNA testing is better suited to confirming its origins grape wise assuming DNA survives the distillation process. This also assumes it is made from Earth descended grapes as if it is an alien plant material DNA as such is astronomically unlikely.
It would be much more straightforward to confirm the age of a spirit as they do now by regulation, bonding and labelling.
What would stop me from taking a vat of freshly labelled Lavian brandy, that has not been matured, and then traveling to some system that is a good 20ly vintage away, and then bring it back again to sell it on as a vintage?
Addendum:
Toying with the notion that faster than light travel, is reflected in DNA is not so far fetched an idea, when one considers the complexity of the epigenome, and how little we know about it. DNA as examined by our computers, is perceived as a block that exists outside of time, so I gather, I'm no expert but do currently understand this to be so.

Well if you are going to buy illegal goods right at the start then nothing.
I would point out that as nothing in the game now travels at sublight speeds why would anyone think that the fact it had been on such a trip make it 40 years old.
light from our sun takes less than ten mins to get here but it is in fact ancient by the time it escapes gravity & collisions
a fine vintage today

Background radiation is unpredictable and probably not useful for dating anything, unless one has precisely measured and logged the exposure.
Overall decay of radioisotopes on the other hand, is extremely predictable, and only needs a reference sample to compare to get very accurate results for sealed objects.
Assuming you're traveling that 20ly at relativistic speeds and not some fantasy FTL velocity that doesn't result in relativistic effects, this would make the brandy younger, not older, than the sample that remained on Lave, or was otherwise kept at lower relative velocities. Even without deliberate tagging, carbon-14 ratio comparisons between a source sample and the sample that was on relativistic ship for even a few decades would show a difference. Using precise amounts of isotopes with shorter half-lives could improve dating accuracy from years to days, or even better over shorter durations.
Bypassing relativistic effects with FTL travel would mean it aged more or less normally and storage temperature would trump any other potential environmental effect. It could still be tested against a sample batch to prove it's authenticity. Beyond that, normal tamper/counterfeit protections would still be in place.
Spoiling wine by exposing it to whatever radiation one thinks would result from FTL travel (provided it was within any limits humans could be expected to tolerate) wouldn't be any more severe than leaving a bottle exposed to sunlight or on an overly warm shelf instead of a cool and dark wine cellar...that's a quality problem that can be identified by seeing how much of the sample has turned to vinegar, not something more complex.
