Black holes, quasars and other stellar oddities
« on: June 29, 2010, 04:07:28 PM »
I'm sure the reason that they're not in the game is because Steve has not thought up a use for them. Post any ideas you might have on the subject.

My ideas (I'm sure you guys can do better)

Black holes: Due to their mass, grav survey would take an extremely long time. That combined combined with their tendency to have no/dead planets would make them undesirable expansion prospects.

Quasars: The same as black holes, only they might emit EM bursts that make sensors go wild, like making "ghost" ships appear.

Well, Black holes could function as extremely heavy stars without light, effectively making for a huge amount of jump points in an otherwise totally dead system.

I'd love to have those in, but I honestly don't expect it.

Edit: They also occasionally emit jets of Gamma rays from their poles.

Quasars could have a very bright EM signature, with the proper maths, you could write up a formula that any EM signatures within x degrees of the star under x% of the signature strength at that distance would pass by undetected, making quasar and black hole systems nightmares to defend, and the wet dream of a Space Rommel trying to sneak behind enemy lines. You could also simulate the extreme EM signature by having a danger zone around the star doing constant EM damage to any ship passing through.

I think this is a (rather common) misconception re. black holes.

Yes, you need a certain mass to form a black hole  (2.3 sun masses, I belive), but the stars, that blew up and thus created the black hole were a lot (and I mean A LOOOOOOOOT) more massive than the resulting black hole. blowing something about 90+% of its mass away when it goes supernova. Only the (relatively) small remaining mass is left concentrated in the black hole. I seem to remember a number of 50 to 100 sun-masses in order to form a 3 sun-mass black hole (All those numbers are from the top of my head, so might be a bit off, but not by an order of magnitude)

Also, black holes are not the "oh, a black hole in 30 lightminutes, we are doomed!" phenomenons, often described in fiction. If our sun would suddenly turn into a black hole, it would be night on earth some 8 minutes later and all life on earth would die some time later for lack of light/warmth, but the earch would continue on its path around the "sun", the moon would continue to circle the earth. A black hole is only mass, just concentrated so much (forming a singularity), the escape velocity is higher than the speed of light.

I'm pretty aware of the properties.
A black hole is likely to result of a super-massive star, and as such, there will be a lot of potential jump points, assuming they appeared before the collapse.
They would probably also hinder Active sensors.

They could be handled like stars, with a minimum size of three solar masses, and and number of Jump Points between one and double the normally allowed amount for that size.

Wasn't Quasars very, very,.... bright cores of very, very,... distant galaxies?

The nearest one is a little over 2 billion light years, so it's pretty far.

But they're just the accretion discs of black holes, not necessarily at the center of galaxies.

I was aware of how they formed, but I made the unintentional assumption that they gain in mass over time(due to "sucking" stuff up). :P

I know how you feel, we watched Armegeddon at school last week.
I spent the whole time trying not to wince.

Yes, that plus too many ideas and not enough time. Any good, workable ideas in this area are very welcome.

waresky, would you PLEASE STOP going to EVERY thread that is even remotely connected to suggesting something and ask for the Army system to be revised?
I've read it about a half dozen times by now, and I'm sure If Steve actually wants to do it, he'll have it on his list already and will get around to do so eventually.

That movie was a great comedy.

I especially like the scene where they are standing outside the vehicle on the asteroid and they are backlit.  If you look down, you can see that they are standing on grass.
