Dark Matter race

Postby May Player » Thu Sep 20, 2012 6:33 am

Dark matter is estimated to constitute 84% of all the matter in the Universe (as per Wikipedia and NASA).
Dark Matter race would be able to phase-in to our visible spectrum. A race like in Babylon V; the Shadows helpers. Very nasty, very strong and secretive. They would work in shadows, trying to avoid direct contact with formidable empires, they would prefer to attack lonely or damaged after some battle ships, kidnap crews, pillage weakly defended outposts and colonies of all races. They would have secret agenda, maybe preparing ground for even nastier, bigger enemy of all..

Using actual science, a dark matter race wouldn't be able to interact with or be perceived from the perspective of light matter races except through gravitational influence. Schlock Mercenary has a good and well implemented dark matter race, but it's only able to be relevant because gravity manipulation is one of the biggest technologies in that setting.

Right, but the actual science limitation we impose on ourselves has more to do with the need to stick with what is 'save and known' rather than something what is possible :) I've read recently on one of NASA websites, that most of the sci-fi technologies are very possible even with today's knowledge, we just don't have the proper materials to build it with..
What caught my attention was, spaceships powered by mini-black holes, dark matter propulsion which is everywhere, creating time bubbles where time runs differently than in normal space. Yes, the real scientists do not say big fat NO to such things anymore. Just such a short time ago nobody new Dark Matter or big black hole in the center of the galaxy could exist. Only 10, 20 years ago any respectable scientist would laugh it this :lol:
Ie. Leonardo DaVinci designed a helicopter, but could not build it in his time. Want M.O.R.E.?

I couldn't agree more.

Here's another interesting article on the relevant topic.

On the same note, do yourself a favor and watch this science approach on Alien civilizations:

Science-fantasy approach at least. I can think of any number of reasons the aliens aren't responding (if they're even picking up), that they're not sufficiently advanced enough to pick the signals up, that they're so advanced that radio to them is like light-telegraphy with torches to us, that they're simply not monitoring on those frequencies, that the signal attenuates to the point of being indecipherable at that distance, that the signal has yet to reach them, that the signal isn't headed at them, that they're too busy dealing with their own situation to bother about us, etc.

However, time travel and limitless power could really screw up game balance.

Now I'm not against interesting ideas, but they do have to fit into the game, so they have to live on planets and fly around in ships.

You are probably talking about real communication issues ;)

Time travel-i am thinking about propulsion, the ship would be enveloped in a time bubble to allow slow passign of time for the crew, so the ship would be with the same crew not a generations-based crew
Limitliess power?
Black Hole - would not be really limitless as it would be tiny (just right to control and power a ship)
Dark Matter - not limitless, just use a scoop to gather it while flying

It's all just fancy names, pretty techs to develop and not by any means limitless. All of it would be really hard to control in large quantities; one mistake could destroy a solar system.

May Player, generations-based crews are not necessary if you have enough energy. The more you accelerate, the slower time will pass inside the ship due do relativity.

Take a look at this site:

http://www.desy.de/user/projects/Physic ... ocket.html

He says: "So in theory you can travel across the galaxy in just 12 years of your own time. "

Also:

"Here are some of the times you will age when journeying to a few well known space marks, arriving at low speed:

4.3 ly nearest star : 3.6 years
27 ly Vega: 6.6 years
30,000 ly Center of our galaxy: 20 years
2,000,000 ly Andromeda galaxy: 28 years"

These calculations are based on a acceleration of 1 g, very convinient for humans. Assuming you had the energy, you would also need reliable engines that would not stop working or you would be unable to stop at the destination... :lol:

In theory we can do anything and it's nice to bounce around ideas. The devs will see what they are able to implement in the game so we all have some fun. ;)

Not really :? . In the case of dark matter for example, the properties of dark matter flow straight from unbending logic:
1. The universe acts like it has too much mass.
2. Maybe there is mass we can't see.
3. Why can't we see it? It is only governed by gravity, not the strong / weak nuclear forces or electromagnetism. Otherwise we could see it.

They're picking & choosing carefully then, or talking mostly about things like high-specific-impulse rockets, laser weapons etc.

May Player wrote:spaceships powered by mini-black holes

Won't work all that well: the amount of Hawking radiation you'll get is determined by the black hole's mass. The best bet I've seen would be to use a rotating black hole's magnetic fields... which of course requires a rotating black hole.

May Player wrote:dark matter propulsion which is everywhere

It's only affected by gravity. Unless we can make gravity as easily as we can electricity, that's right out.

May Player wrote:creating time bubbles where time runs differently than in normal space

If you can muck around like that you can probably make an Alcubierre warp drive that runs on a reasonable power source anyway :P .

May Player wrote:Yes, the real scientists do not say big fat NO to such things anymore.

I think you're confusing "we can't rule it out" or "the theory says it's possible" with "the engineering is possible". Ie even if rotating black holes exist, until you can (1) make them to order and (2) build the rest of the machinery around them, they're no use as a power source.

Like that thing above about travelling across the galaxy in 12 subjective years. Sure, but the trouble is we don't have a power source to let us do that, never mind deal with collisions or course adjustments at c-fractional velocities etc. In other words, it's just a nice way of showing you how even low acceleration figures can quickly result in very high velocities.

May Player wrote:Just such a short time ago nobody new Dark Matter or big black hole in the center of the galaxy could exist.

People have thought about there being something big at the centre for ages (eg Doc Smith's Skylark books had the Green System IIRC, and even a "dead star" that is extremely black-hole-like, long before black holes were theorised to exist). Once black holes are theorised to exist though, one in the middle of the galaxy is a perfectly logical conclusion. As for dark matter, see above.

May Player wrote:Only 10, 20 years ago any respectable scientist would laugh it this :lol:

1971 was when a supermassive black hole in the Milky Way was first really considered; it was discovered 3 years later. And in the early 1930s astronomers began to notice that distant objects appeared to have huge amounts of "hidden" mass.
Clear ether!
