The graphics of the Suns in eve has always been a thing that bothered me. I hope they update it at one point.

I fully support any effort to make EVE feel more real!

Wow. That was really arrogant and condescending.

Did you actually look at what you linked? The author isn't talking about angular (apparent) size, he's talking about a point source's apparent magnitude from Pluto. So, yes the Sun would look like a pinprick from Pluto. A magnitude -19 pinprick on average, but a pinprick nonetheless. As for seeing your hull, you would be able to see your hull, I think, at Pluto's distance (which, I might add, is only ~40AU, compare w/ some eve systems 200+AU across... ) but the light would be so low I don't think your brain could make out the colors. We're talking ballpark 80lux @ 40AU (simplified for quick/dirty/bad math). ...get out to 100AU and lemme tell ya... it's gonna get dark.

I think the level of science knowledge players have is pretty damn good. [emote:middlefinger]

oh this is fun. thank you.

this is a direct quote from the article i linked to my OP (mind you, the line of text was in bold in the source material as well)

--
From Pluto, the Sun is fainter than it is from Earth, but still can be 450x brighter than the full Moon.

Well, let’s compare that to how bright the full Moon looks from Earth. To us here at home, the Sun is about 400,000 times brighter than the full Moon, so even from distant, frigid Pluto, on average the Sun would look more than 250 times brighter than the full Moon does from Earth!

now here is what you wrote in response to having read the above text:

--
"but the light would be so low I don't think your brain could make out the colors"
--

quick/dirty/bad math time:

lets say you are 100+AU from the sun, it would still be something like 100 times brighter than the full moon appears to be on earth. dig it?

You should add to your list:

Why can we warp directly through ships, stations, planets?
How can anything exceed the speed of light?
Why don't the planets orbit their stars?
How can a tiny ship bump another ship of insanely bigger mass?

The answer to the above questions, as well as your own, is that this is a computer game.

Post with your main, like a BOSS!

And no, i don't live in highsec.  As if that would make your opinion any less wrong.

What is this hip-shot math you are using? Yes it has a much lower magnitude than even the moon, but magnitude is determined by point brightness... or brightness over a given area (watts per square meter). If the source is a point, despite being of a low magnitude the overall brightness of the area is not significantly increased. here.

No dude. Inverse square law... as a point of light low magnitude but the actual light per unit area reaching Pluto or whatever is JUST the light PER UNIT OF SQUARE AREA is arriving at 39.whatever AUs. If you think a POINT source of low magnitude is significant, you better chickity check your denominator, before you wrickity wreck your self. Yo. ..and watch them exponents.

edit: in truth there is brightness coming from the sun which is why the light in the area is around 80 lux, and that's b/c the sun isn't technically a point source. It has a small albeit significant cross section. That with the low magnitude gives it some output even at pluto's distance, but not much.

dude you dont need to do math to figure this out. you said you wouldnt be able to make out color. the article clearly states otherwise, describing the light level as being similar to moonlight here on earth...which we can all see in last time i checked.

just read the article. if you dont understand it i cant help you any more than I already have. Im not a teacher.

frak it lets do this, i like arguing:

"Firstly: eye sensitivity (according to this: http://www.lifeslittlemysteries.com/2426-human-eye.html and wikipedia). The least amount of light detectable by our eyes is at around 140 photos at a frequency of 587.8THz. From E=hf (Planck's relation) we have each photon carrying 3.9*10^-19 Joules of energy, hence a bundle of 140 of them would carry 5.46*10^-17 Joules. The "response rate" of the eye is about 1/10 seconds (http://en.wikipedia.org/wiki/Frame_rate#Background), so we would need this bundle of photons to hit our eyes once every 0.1s for us to detect anything at all. IE we would need 5.46*10^-16 J hitting the area of our pupil per second. Now a fully dark-adapted pupil is around 9mm in diameter, which is an area of 6.36*10^-5 m^2.
Soooo to get a detectable amount of light hitting our eyes, we would need at least 8.58*10^-12 Joules per second per m^2 hitting the surface of whatever planet or spaceship we happen to be on.

Now we need to calculate the light falling on Pluto from the sun. According to Wikipedia, the average flux of light from the sun at the distance of Earth is 1360 J/s/m^2. From this, we can derive the flux from the sun at pluto (the ratio of the squares of the distances to earth/pluto times the flux at earth): 1.23 J/s/m^2!

This is way more than our supposed limiting flux of 8.58*10^-12 J/s/m^2! So at Pluto we'd almost certainly be able to see things around us.

Now for 2 light years away, the same applies. 2ly = 126 482 AU, therefore flux at 2ly from sun = (1/126482)^2 * 1360 J/s/m^2 = 8.50*10^-8 J/s/m^2. Again over our limit, but only by a factor of 4 now. It might start getting a bit tough to make out anything meaningful, but theoretically it is possible."

He was talking about the magnitude. The lower magnitude = incidental light received from the sun, not total light. The total light received per some area at a distance of pluto (the light you see around you sitting on Pluto mid-day) is exponentially less the further out you get. It gets dark as you get out there a ways... it's not really bright out there. Unless you're in a star cluster or something...

the article clearly states several times what the light level on pluto is. ive linked you the article, ive quoted here for your convenience the key sections, and ive found an interesting little bit of math that proves my point in a different way. if you cant grasp that....im sorry!

you can see stuff on pluto. get over it.

While it has never bothered me, it would be something i would like to see implemented in the future.
Also i would like to see a wide variety of stars including;
-Pulsars
-Magnetars
-Actual Binary systems
-Binary systems that have gone supernova
-Stars being assimilated by a black hole
-Red Giants
-White/Brown Dwarfs
-Quazars

Also assuming the New Eden is a Galaxy, Where is the Super Massive Black Hole at its centre?

So let me get this straight. You have no problem with the jabberjaw doubletalk pseudo-scientific and physics-breaking underpinnings that make up this economic simulator we all enjoy so much, but you very much have a problem with the apparent size and constant illuminative qualities of the stars and suns?

Some small notes here,

- Pulsars or spinning neutron stars have a much stronger gravimetric pull on anything and would squish us in close proximity (1ly at least)
But I will make cake for anyone who comes up with one system that has one (and they look cool)

- Magnetars, while being the coolest of the bunch, could rip the iron particles out of your body and "spaghettify" you at 100au distance to them, so warp to zero is a clear no no (but they look cool too)

(One the other hand if we could experience a star quake from a magnetar...)

- Quasars are large (and I mean very very very large) galaxies with a giant black hole in the middle that spit out "jetstreams" of enery out of them at the speed of light (up to 2 million lys) from both poles of the black hole so that would very much only be something you would want to look at from a great distance.

Though I guess as backgroud image or appearance with some tiny slow movement can be done (make the art developers watch all the cool "The Universe" and "How the Universe works" documentaries of youtube to get ideas).

Remember we "live" in one galaxy or the bigger part of what we know about it.

And since all we do is kill each other in different ways nobody "investigates" (but I'd love to)

- As far as binary system go, I thought they were the common "thing" in the universe and single star systems are the rare ones.
And didn't they say that our gates were "powered" by the companion stars for the gate network to work and our gates could only work in those binary systems?

- Black holes would also be bad since nobody can see them, because they are black and slurp even light.
What we could see is a star or more that "orbits" (well the orbit wouldnt have to be a circle) a black hole.

And I would recommend a security distance from at least 1 lightyear away from it unless your jumpclones are cheap Lol

- Red Giants, agreed that would be really cool to look at and shouldn't be too difficult and what about the white/blue (more focus on the blue-ish look) stars?

This has been the one visual oddity driving me nuts since I started playing. The size/brightness of the stars based on the distance travelled never seems to change (unless you warp directly to the star).

Our Sun from Neptune (~30 AU), for example, is practically a small dot in the sky.

Yet anywhere you seem to warp within a system in EVE, the star is always the same. It would add such a tremendous sense of scope/distance to warp away from a star and see it shrink to just a burning dot in the sky.

(And for that matter, where are the double binary systems and red-colored stars and brown dwarfs and other fun stuff? Screw the science I want to feel like I'm zipping through exotic solar systems of all types and colors.)


What you hear and what you see in EVE is a simulation made by your ship`s computer. You aren't a floating entity that always stays behind your ship zooming in and out. You are inside the ship, plugged in, inside your capsule, which has no windows, floating in a liquid.

Everything you feel is a simulation. That warp tunnel, also a simulation, that sun light, also a simulation. In theory you could fly a space dildo through pinky clouds, but you have chosen to mimic the reality. Thus your board computer gives you accurate information regarding the shapes of the environment, so that you can take swift decisions. The "image" of the sun is only in your mind, augmented by a soft, so that you will always know where you are in the system.

The warp to 0 sun, is a software limitation Your are most likely warping to 1 AU.

Hope this helps with the immersion.


People seem to have missed the fact that this guy pretty much answered the question flawlessly.

Also enjoyed the poster above who did a fantastic job destroying the guy who tried to claim that it would be "too dark to see" 40 AU from a sun.

I always like the "science" posts that address the EVE universe; partly because of the idiots who come up with easily answerable questions (makes me feel better about myself) but mostly because a few players really ARE smart, and come up with great answers :)

how big something appears in the sky has no direct on how bright it makes the space around it. at least not in the way you are thinking. yes we get it, the sun would look like a large star. a pin prick. but that pin prick lights up pluto enough for you to see stuff pretty clearly.

simple logic, take a strong LED and place it next to a weak traditional bulb.
