Fdev, Y-Dwarf stars should be dark

[Shinji Ikari]

It does; the "afaik" suggests assumption, yet again. I feel like you are just arguing now to score points and to be seen to be "right". Okay, you fly safe.

You have as much evidence as I, all of what I say is from reading Elite lore or from personal experience.

Edit, sorry I already said this duh, I don't know how to delete this post. :S

Expecting a 1:1 match with reality is a bit foolish when we barely understand how even half of the technology in the 33rd century works, let alone most of it is theoretical at best at this time, most of it is unproven and never mind that most of our understanding of black holes and other stellar phenomena, whilst improving greatly over recent years, is still mostly theoretical.

We have managed to observe some phenomena that lends credence to various theorems; but it's not all completely understood. Frontier do their best, and unless they hire on a theoretical physicist, astronomers and mathematicians, this is about as good as it'll get.

I don't understand most of it. And the bits I do understand, would suggest to me that if the game actually simulated things as we believe they are, it'd be incredibly boring for the most part. The universe operates on glacial time scales, not on the rapid cycle that leads to adventure and excitement.

1º KSP is a game that has probably the most realistic physics ina videogame and it's fun if you are the right person.
2º A "theorem" is a term used in math, generally not in physics or even science in general.
3º I wasn't even talking about black holes, I was talking about the topic of the thread, the mechanics of Y Brown Dwarfs are not a subject that pops often in relativity or quantum physics and I've never heard that they are one of the issues between both models. (I watch a lot PBS Space Time).
4º Physics doesn't seem to be completely alien in Elite considering the way ships fly, the gravity in space ports, the shape of the galaxy, the stars positions and the stellar classification which is related to the OP's topic. All 21st century knowledge

I'm ok with dark systems and dark planets as long as we get some thermal imaging or something a bit better than naked eye.

I seriosuly doubt that, otherwise we would see a faint red glow on everyday objects.
"near room temperature, a blackbody emitter (such as a human body or light bulb which is turned off) will emit low power radiation at wavelengths predominantly greater than 1µm, well outside the visual range of human observation."
http://www.pveducation.org/pvcdrom/properties-of-sunlight/blackbody-radiation

We are talking about a star sized black body. There's a hell of a lot of radiation coming off these things. Only a very tiny fraction is in the visible spectrum, but in the blackness of space, you'd see it.
Also, just like Jupiter, there would be .some pretty violent weather on these things. The temperature wouldn't be constant, so some parts of it would be higher temperatures. And weather would mean lightning, some of which would be visible from space.

Maybe you could see lightings from time to time though I'm sure you would have to be very close to them, about the tiny visible fraction you mention, I'm still very skeptical it would be significant enough to be visible, even when it's night, in rural places and it's new moon we don't see any light coming from normal objects at all.
I've done a bit more research and according to "http://www.spectralcalc.com/blackbody_calculator/blackbody.php" the band radiance for the bandwith between 0.39 and 0.7 micrometers (or the visible spectrum) would be 1.33111e-23 W/m^2/sr for a 300 K object. I do know what a W/m^2 is, but I don't know what is the unit contribution of the sr or steradian in here so I can't do much with the answer I got though I know for sure that 0.0000000000000000000000133111 is a small number, very small.

Edit: Brown dwarfs are about the size of Jupiter which itself has a surface area of 6,41×10^10 km² or 6,41x10^16 m^2 for comparison.

 

[Limoncello Lizard]

True. I did say it was a tiny fraction. But a star is rather big, even a small one. And, like I said earlier, the temperature won't be even.

Even with the huge size, it doesn't seem that it would be enough to even pump a watt of visible light if the unit I got is remotely similar to a W/m^2.
I don't know how big the temperature changes could be but if I assume some areas get like 100 Kº hotter then the band radiance would be 4.94618e-16 W/m2/sr which is still very little.

Black holes aren't finished yet. They're just visual placeholders.

Not to veer too far off topic, but where did you get that information? One thing that has bothered me about this game since I got it is the poor representation of black holes. You know, the complete lack of an event horizon, accretion disks, inaccurate gravitational lensing, etc.

What exactly do you expect to see with an event horizon?

 

[LJITimate]

it would be cool to navigate dark systems. I personally would like to see the hud still display planet perimeters, orbit lines and other info like that as normal as I assume it normally figures that out through sound or something not related to light. would also bee cool to have proper dark sides of moons as it would give a use to the altimeter and stuff

 

[LJITimate]

just saw a thread on the horizons sub forum of a moon under an eclipse and apparently it doesn't have the artificial lighting, it looks so cool, they need to add dark stuff into the game

It'd also give a reason for SRV's having lights!

good point. thanks for sheading some 'light' on the situation

I'm sure it was. I remember being in the dark in my SRV. Very eerie. Unless I dreamt it!

 

[SkipRat]

Because it's kind of a bummer to go to a system where you can't see anything more than 500 meters in front of your ship.

Use your ship lights then..

Would be awesome to have some scaryass systems where you are flying blind using your ships instraments.

Oh yeah, sorry, I forgeot. This is elite wimp, where the game is developed for those who are scarred by clouds and cry about any kind of effort being implemented.

Yeah, thanks to almost no light in this planet I got some nice pics.
