new DLC !

Inertia outside the gravitational field is also impossible! Don't forget!!! The gravity of the Sun and the Earth are different!!!! And when you leave the Earth's gravitational field, you find yourself in the SOLAR gravitational field, which holds entire planets in the solar orbit!!!!......
.. In other words: you don't know how strong the sun's gravity is until you try to get close to the sun or leave the solar system!

Bizarre ranting, we know exactly how strong the suns gravity is because we have sent a probe out of the solar system beyond the possibility of recapture by the sun, it's now beyond the heliosphere and in interstellar space, and you know how we did that, by knowing exactly how strong the gravitational effect of each body in the solar system is, including the sun, and using gravitational slingshots to accelerate it. I mean you really are ranting now, I keep suggesting taking this to a different thread if you want to continue, but here we are again. Umm, I don't really think you understand inertia either, but that's not surprising. Although I should point out that as I said earlier the attractive effects of gravity is as far as we can tell infinite so there is nowhere in the universe that isn't affected by gravity.
 
I suppose the OP understands that there is per se no gravity at all in the game, it's just smoke and mirrors and has precious little to do with reality..

In essence the game is just drawing pictures on a screen trying to trick us into believing that we are in a universe where there is gravity.

.. and also.. we live in an era when they try to hide the truth! And I won't be surprised if it becomes known that contact with this probe has long been lost and it has NEVER flown beyond the solar system))aaaahahahaha
.. yes! It's time to stop ranting! ED is just a game that simply invites you to DREAM about space exploration. And nothing more.
 
Funny, a definition of gravity would need to account for everything we see in the universe, the accelerating expansion of the universe is certainly not accounted for by any current definition of gravity, loop quantum gravity and non-contiguous spacetime are two theories competing to explain it but are still not there. Dark matter that supposedly explains the incorrect rotation of galaxies that should be covered by gravity but isn't, has not yet been observed to exist, and dark energy is supposedly a quantum effect, at least that's the general idea at the moment. We still don't know exactly how Higgs field gives objects mass. A definition should account for all these things. To claim that the only thing not accounted for by gravity is at cosmological scales and therefore don't count is just begging the question.
[Cold] dark matter postulates that there is more matter than we have yet observed or inferred, and if there is indeed more matter, then gravity's just fine thanks.

Similarly with dark energy; if vacuum potential is higher than thought or empty space holds energy through some other mechanism (moduli or whatevs) then gravity's just fine because that there 70% of matter-energy that shows up as dark energy is the right amount for gravity to work.

So really no-one is questioning gravity, they are questioning either the fundamentals of QCD and QFT, or proposing an alternative to it like LQG, or wondering whether discrete time might be the issue (I've started Carroll's book, it's mindblowing), or whatever. It all amounts to "there's a bunch of energy hiding somewhere, but where, and if some of that energy also has rest-mass, why the hell can't we see it?"

But those are all changes to other theories so that spacetime can stay the same shape and gravity can still work like what it has since 1915.

Not saying that's going to stay that way forever, but the vast majority of current thinking is about changing other parts of the total modal of the universe so that gravity can stay the way it is now. No-one's taken the MOND guys seriously for a while now.
 
well luckily for me you quoted all of my post before I could change my mind end edit it :D. It's just not woth the hassle to discuss conspiracy theories. You can only lose.

And the Earth is flat.

(wrongly depicted in this game, but hey, they didn't want to alienate the prevailing round Earth conspirators)

Oh yes of course, problem is no-one has yet detected dark matter in any form apart from that it could exist because it appears to be exerting gravitational effects on things like galaxies, scientists currently postulating a theoretical particle called an axion, WIMPS are just about out of the running now. Cold dark matter could account for it, but we simply don't know.

As far as dark energy, current proposal is a form of energy field that doesn't get weaker as the universe expands, in other words even if the space it occupies grows the level of dark energy per given volume remains the same, so it increases to fill the space created, and so the total amount of dark energy increases as the universe expands, thus driving the accelerated rate of expansion of the universe, but again it's something we simple don't know yet.

Lots of people working on this stuff, and new ways of measuring and observing may give clues as to what exactly dark matter and energy is, new detectors being built and observations using gravity wave observatories and new ones proposed for the future, it may be one of the these will finally have a major breakthrough, here's hoping it's soon, would be nice to see these things discovered in my lifetime at least.
