Title: Need a Black Hole Background
Post by: Noise on April 01, 2003, 06:21:04 pm
Part of a future chapter in my Into the Depths of Hell campaign is a battle around a black hole.  I was wondering if anyone has a good background that I could use?:)

Um...Make a multi-colored, amphorus disk in PSP or Photoshop and stick a small black circle in the center.  Then when we put it into a mission, have all the nebula seeming to be flowing toward it.

You probably don't want the battle to take place too closely to the Black Hole or we will have to alter your plot to take into account the temporal flow differential.

or make FS ships fast enough to escape the event horizon :D

It is just annoying that some people notoriously steal my coolest, top secret, unpublished ideas ! ;)

:yes:

Anyways, how about this piccy courtesy of Google Image Search:

pfffffffff

why do you think I did this (http://www.3dap.com/hlp/hosted/ott/renders/ottbh.jpg) render a while ago?
lots of blackhole everywhere :p

Not knowing precisely how a Black hole should look, the best I can offer is this:

make the core pure black, and you'll have a nice scifi black hole :)
knowing how a blak hole reall looks like wouldn't help you much, it's weird and doesn't look as cool as the "multicolour light spiral phreakazoid saucer" thinguy ;)

i think a BH should look more 3d black wolf...something like venom's... with a deep (black:rolleyes: ) hole in the middle of a colored vortex. The point is that the hole should look mmm like the cone of a tornado seen from top
and the vortex should become darker and darker as you get near the center

The hole was black once, but somewhere between finishing tyhe image and posting it here (ie - decreasing to 256 colours and jpegging) it turned that sort of grey blue. Fixed in the final pcx though.

As for getting darker, scientifically I'm about 90% sure it'd go the other way - get really bright in the centre, then a point of absolute blackness in the very centre... but I'm not certain.

If it's not accurate enough, just don't use it. I'm still pretty happy with it as just some sort of vortex, if not a proper black hole.

Looks cool !
But how come the fighter did get out of it ? :rolleyes:

Problem is that you could only look at the BH safely from another star system (or at least from a similar distance), where you would not see it from at all.

Apart from that I would put a giant star on the pic, the material from which is sucked into a dark point on a swirling route.
A good example for this can be seen in one of the FS2 cutscenes, where Bosch is standing in the Iceni's window.

That's not a BH in the cutscene - I think it's called a neutron star - when one star in a binary system is superdense, its gravity sucks stellar matter from the other, causing that phenomenon.

FS2 ships have pretty good radiation shielding (witness how the entire crew doesn`t get killed off by gamma rays whenever an antimatter bomb goes off) so there wouldn`t really be anything to stop you getting close enough to a black hole to observe it.

Getting close is not a problem. Getting out is what I would be anxious about. :)
Concernig radiation, a BH is a safe place cos' it emits nothing.

Neutron star: Isn't it the thing which turns into a BH ?
I suppose the effect is similar. Enormous gravity which sucks in material from close stars.

anyway, the matter sucked is from a nebula, not from a star.

Okay we have a case here where an example would prove useful.

Suppose tomorrow the sun magically (and it would have to be magically since it couldn`t occur naturally) turned into a black hole. What would happen to Earth.
 The answer is surprisingly little. The Earth wouldn`t go spinning off it's axis and flying towards the sun like most people think it would. In fact the Earth would continue in its normal orbit with no new effect whatsoever from the black hole. (of course life would be wiped out due to the lack of a star etc)

The reason for this is that gravity is a function of mass. A black hole in the same place as the sun with the same mass as the sun would have exactly the same effect on the Earth as the sun.

So since a black hole has no more mass than the star that created it (in fact it has less since it loses mass during the supernova) it can`t really affect objects far away any more strongly than the star it was created from did.

However once you get within the radius of the original star then you get problems. 5000 miles into the sun the gravitational pull is actually less than on its surface. This is because the gravity inside a sphere actually gets less and less as you approach the centre (since some of the gravity from the mass below you is cancelled out by the gravity of the mass above you).
 In a black hole you don`t get this effect. The gravity just keeps on increasing until you reach the singularity. That's what makes a black hole so dangerous. The closer you get to it the more strongly it pulls you, but as I said this effect only makes a black hole dangerous once you`re within the radius of a star of equal mass.

As for radiation black holes do in fact emit large amounts of gamma and x-rays whenever they eat something. (can't remember if they only emit from the poles or just mainly at the poles though).

This was actually quite a good lecture. :)
The only thing I would add to it is that it is not the BH which emits X rays but the matter falling into it:

OK, OK.
So here is a psychedelic "concept work" I did last year with my daughter (4). She started with spraying red dots on a black background in Paintbrush and I drew inspiration from it.
;)  Haven't worked on this since then.

lol
sorry but I keep telling people "yeah, I mihgt help you" but finally I don't/can't. Had to resign from the SC conversion already, can't join something else.
And to be honest I think I'll turn to FL in a very close future ( well, when the game is out in France and I've completed it:
I can make the ships in 3dsmax, convert them to 3ds, open this file in milkshape where I'll place gunpoints and stuff, and convert them directly to the game. Nothing like all the hassle to make a pof with truespace and **** ).

That's actually quite a nice site. I`ve sent in a couple of more advnanced questions when I`ve had problems and they've generally sent back an answer within a couple of days.

As for the short lecture it's better to correct a few misconceptions quickly before this ends up like the "No G-Forces in space" thread :D

You people are aware that if one were in the "system" of a black hole, one wouldn't see the accretion disk, aren't you?  One would be in it.   If one wants to simulate this properly, one needs a black spot in the sky about the same diamater as the usual sun would be, and nebulae all around, not an outside shot looking in at the accretion disk.

Unless of course you are above the plane of the system. In which case you should be able to look down and see the whole thing :)

Hollywood spruces them up a bit.. However you would see the disk IF it ws in the process of eating another stellar body (ie close by planet or gases, ect...) at least until it reached the event horizon.

I guess, but in that case the image had better fill up fully half the sky, and have some good perspective rendering in it.
