I want an alternative to the Alcubierre drive. Also I want to be able to FTL within the solar system regularly. There should be many methods to FTL, especially if there are multiple different civilizations around the place.

Any reason why you want an alternative tot he Alcubierre drive? And there's nothing from keeping you from FTL within a system with the Alcubierre drive. And once again I disagree, its more than likely that the different civilizations would have made major items more or less the same way, i.e. gunpowder, petroleum powered engines, and nuclear power, FTL would most likely be the same way.

@ Mal: Halo's slipspace is hyperdrive with another name.

Just a thought: Since all of these technologies are purely theoretical, wouldn't any one of them do?

Yeah I want multiple techs that do the same thing

[Surdra]

says the guy that just suggested that we do that

[Mal]

Sorry. I meant couldn't different interstellar powers use different propulsion methods. I think in Star Trek, the Romulans use a different method than the Federation.

I was just trying to find a middle ground is all.

[Surdra]

ya we could use different engines and fuel but I highly doubt that any FTL systems would be so vastly different.

For example, different nations build their jet engines differently, but when you get down to it their use the same theory. Air forced in, compressed, mixed with fuel, ignited, and then shoot out the back producing thrust.

[Surdra]

were tabling FTL talk for right now and we'll pick it up later.

So who wants lasers like in star wars and star trek?

on a another topic we have artificial gravity, I think we diffently need to have this. Not only does it make it so our guys can walk around in their ships it also opens the door for some cool things to be made.

Artificial gravity is a must. If we stick to no-gravity ships, we are heavily limiting what is possible within the spacecraft of the time.

[Surdra]

agreed and there is a claim that it might be done with spinning superconductors at super high speeds, granted they only were able to create on millionth of a G, but it gives us something to base it off.

[Globexanter]

We can say that, shove it in a box and then try to avoid talking about it too much

[Surdra]

yup. On another topic Bolotor, Nox, and I we talking last night about our top sub-light speed. So how long do you think it should take to transit the distance from the sun to earth or one AU? We talked about it taking just under three hours at top speed. (Not this doesn't include the time required to build up speed and to slow down or anyother factors that would increase the transit time.)

Not that anybody would want to travel to the Sun...

Three hours is good; that's 180 minutes compared to the 8 minutes that sunlight takes to reach the Earth. So we're still 22.5 times slower than light, which is not bad. ;D

I'll leave the technical aspects to you guys. I'm not very good in science, much less theoretical science.

[Surdra]

well to put it another way at the same speed its 4.5 days from the sun to pluto, a very respectible time I believe.

[Kannex]

Interstellar travel will involve faster-than-light travel, correct?

Yeah

Yeah

Thought so, a 90-year trip to Alpha Centauri doesn't sound very convenient.

[Surdra]

well keeping with speed how fast do we want out FTL to be? On average stars are about 4.5 light years apart.

[Bob10101010]

So are we useing hyperspace drives and hyperspace drives.

[Surdra]

we decide to table that for right now and pick it up later.

Hmm I would prefer days to a week.

1 LY/1 day=365.3 c (about warp 6)
1 LY/1 week=52.17 c (like warp 3.5)

SPOILER: Click to show

For comparison Star Trek speed. To nearest star is 5 LY on the tables.


Key
*:400,000 kilometers
*2:12 million kilometers
*3:5 light years
*4:20 light years
*5:100,000 light years

[Surdra]

I think warp 5 or around 214c will be right on the money

[Boltor]

Well I think the speed should really depend on how far the edges of the star map will be and our relative distances to each other. Going to the next star in 9 days is okay , but someone 5 star systems away can be around 40-45 days which is kind of ugh. Not to mention not every adjacent star will have habitable planets/colonies.

[Surdra]

well unless we are all going to have like 150 systems from the start I don't see our first map being that big and we can always increase the top speed as it gets bigger.

[Surdra]

speaking of which I guess I should get started makign the map. Arould how many systems do you guys think we should start off with.

so far my idea is to let everyone design their home system how they like (with in reason) and from that point on every other system will be made at random by a generator I found.

[Kannex]

Let's start a conservative 3 or 4 (including the Solar System).

Do we have a date for our Sci-Fi A setting?

[Surdra]

thats what we were figuring for brand new guys, for us that the launch we were thinking a bit more

I was thinking 2500 to 3000

[Boltor]

Nox liked 2750, I'm more a 2751 kind of guy ;d

[Surdra]

ugh

[Surdra]

extra planets would be listed afterwards along with things like asteroid belts. Moons and other major satellites (like space stations) would be listed after the object they are orbiting.

For example, Mino's moon (if it had one) would be listed as #1.1.
