Rules Questions


Okay.......heat and cold transfer very slowly in space (you can't freeze to death ,your body freezes long after death) you might cook from infrared and other radiation if you in the wrong spot ..but actual heat transfer if you were in a hot spot would happen much slower ....conductive electricity doesn't travel threw a vacuum (magnetic waves and photoelectric only) ...sound doesn't transfer either .....so that leaves laser and maybe plasma and projectile(if they all use the right explosive) and a couple others like infrared heat weapons and radiation weapons ....any rules on this ? I'm guessing no


oh yea forgot acid which would just evaporate in the vacuum ...i guess nanites would work


No, no rules on this. The weapon types all work in space.

Because science. :)


yup ..figured as much ....lol tell me about it...maybe my follow up question should be... why is the mass of my planet x5 but the gravity is x1 ...unless it meant the whole system ....but there are like 9 planets in the Veskarium so that just raises further questions


Actually, there isn't a hard connection between mass and surface gravity. It depends on the radius of the planet, and thus indirectly its density. Assuming a constant density, gravity at the surface will vary roughly with the square root of the change in mass, so a planet of mass x5 would have a surface gravity of about x2.4.

( This is why the moon still has 1/6th Earth gravity, despite being only about 1/36th the mass of the Earth. Smaller radius. )

So, a planet being mass x5 and gravity x1 is not that horribly implausible. It just means the thing is fairly low density, and so larger in radius than an Earth clone. Now, whether this is actually possible in reality, I can't say off the top of my head, but its certainly nowhere near the most impossible bit of astrophysics in the setting.


all true but it's very unlikely it would be 1 G unless it was almost entirely water...lol and I had to biotech my swimfins...still good point though... "chuckles" maybe styrofoam is a naturally occurring compound on my planet (WOW.. and now my brain jumps to that slow lizard man chucking rocks at Kirk)

i think globs of acid would work just fine in space in the time it would take to travel and hit the target. If it missed then yea solar wind might evaporated in some time.


It's more that things that are liquid at normal earth pressure sublimate into vapor in a vacuum.

Moot either way, since there's no rules saying it doesn't work in space.

I'm trying to figure out the Cathode Cannon (in space and in general). In theory it would basically ONLY work in space, but it gives no indication of that. But more important to me, what color lightning does it shoot? It would probably depend on the elemental makeup of the air it's shooting into, which would depend on the atmosphere of that particular place.


Leave realism at the door. The only thing that matters are The rules regarding the items in question. If the rules say it works, it works. If you get hung up on attempting to compare a games mechanical system with reality you are in for some rough times at the table.

Don't attempt to rationalize. Just enjoy the rules. Kinda like Star wars and all the laser sounds in space. Apparently, in Lucas`s world, space isn't a total vacuum. Pew pew pew


thistledown ...The basis for a Cathode Cannon is a electron gun like in the back of and old TV ..It would likely have a vacuum tube inside it for concentrating the electrons as an electron gun does and an element to accelerate them ...and most likely you can't see the shot at all, also damage from it really would be more like radiation damage from accelerated particles (electrons in this case) ...and said elections pass right threw thin pieces of metal air wouldn't be a problem and in this also probably would work in space (falls under "and a couple others" in my original post)


probably shouldn't be a electricity damage weapon...but that would confuse many


And It does appear there is nothing covering energy damage and by the rules they all work, not debating that or anything ......I was just wondering if the addressed it in a faq or something ........

Hey Magyar ...want a starwars question no star wars trivia buff can ever answer "can ships with their shields up fly threw the shields of other ships " why ? because sometimes they can and sometimes they bounce off and explode ...either that or there is a lot of raising and lowering of shields going on that no one ever talks about


It has to do with the resonant frequency of the shields of the ships in question. If they are are too similar then they bounce off one another. Especially since the frequencies are modulating to ensure that energy weapons can't alter the frequency to bypass the shields.

;)


actually that's the best answer to that i have ever heard ...I'm gonna have to give you the points on that one

There are no sounds in space, not even in Star Wars. Ship sensors detect events around the vicinity of the ship and create audio feedback to the pilot so that they can maximize their reaction time using their natural senses.


I dunno. Every time I watch a Star Wars movie and the camera is in space I hear all kinds of sounds. Especially if it's a shot of the rear engines of a big Star Destroyer. Or like that time R2D2 got out on the wing of the ship to repair it. Them dying drones were making all kinds of death sounds as they got blasted into smithereens.


As a matter of fact. The more I think about it, the more it makes sense that space in George Lucas`s world behaves more like an atmosphere than it does space. The fighter jets have wings. All kinds of dying sounds. Barrel rolls are a thing as is crazy atmospheric based maneuvers.

If you think about it. Shooting things in space would be super easy. Nothing makes sudden movement changes because there's nothing providing resistance to be leveraged for such maneuvers. Of course... then the action would be boring.


Yea.. space battles would be dull and quick if physics in space were realistically considered. I prefer Lucas`s version of space. Now if only the bad guys shot red lasers and the blue guys shot blue lasers it would be the perfect blend of GI Joe in space

Lots of sci fi has shooting things be super hard, because you engage at distances with enough light speed sensor lag (or projectile/missile travel speed lag) that that the targets can constantly burn attitude thrusters to jink side to side and up and down on their mostly straight trajectory.

Donaldson's Gap series uses light speed lag (and near light speed weapons) plus "particle sinks" that absorb a lot of the impact of the light speed weapons so that you need to land most of your shots.

The Expanse uses projectile/missile speed lag - against long range missiles you can burn hard to extend the range and adjust your angle so that your point defense weapons have a better chance at shooting them down, and you try to avoid short range where rail guns can hit you faster than your random turns can escape the firing solution.

I believe that's one reason the timing and hex distance of space combat is left vague in Starfinder - you can flavor it as one of these options. You can even consider the "swooping" and maneuvering around each other aspects a false abstraction of long range combat where the actual maneuvering is in the short term to dodge projectile and rotate weapons' facings against particularly vulnerable parts of the opposing ship during their own dodges, while in the long range you are adjusting range to maximize or minimize certain weapons effectiveness and adjust ranges between multiple combatants to focus or evade fire from individuals.

Depending on their engagement vectors this can be several short engagements where they cross paths (followed by hours of turning around to reengage or pursue in a tail chase), one short engagement after which one ship has no chance to catch the other one, or a long drawn out combat at long (and slowly decreasing or increasing) range when vectors are approximately matched.

Expanse and Gap battles can last hours between two ships. (And also minutes.) There's plenty of maneuvering to dodge and bring weapons to bear, but they don't have to and often don't get close to each other.


Yeah, you usually get one of 2 things in sci fi space battles.

Either there’s widespread inertial dampening technology, in which case you get those close up battles with fighter dogfights and capital ships that see each other with the naked eye while they trade shots.

Or

‘Realism’ shows up and battles take place with hundreds, if not thousands, of kilometers between the ships, and you need complicated math to get your munitions to intersect with where you think the enemy ship will be in 50 seconds. Your missiles need the best on board computers, and your target will certainly have an outer layer ECM defense and an inner layer of point defense weapons.

If you all haven’t yet, I really recommend the Honor Harrington books for neat space battles. They run basically like wet navy fights in the age of sail.

Two anime that surprised me in how they portrayed space combat.

Infinite Ryvius goes the Realism route. Space battles are a lot of slow maneuvers and calculations. Even when they bring the giant mech into it.

Crest of the Stars has very nice fleet maneuvers, but the battle of the Geshpent near the beginning of the show takes it for me. When your main offensive weapon is a rail gun that only fires along your keel (though it CAN do for AND aft), it takes time to swing the ship around. And when you're surrounded by multiple attackers...


All I know is that physics is a harsh mistress. I tried to juke gravity the other day when I misfired taking 2 steps at a go while chasing the cat up the stairs. My knees and ankle decided that it takes very little force to rethink my assumption that I'm still as young and spry as I was 20 yrs ago.

Here's an interesting little tidbit of knowledge related to space. We know more about space than we do the intra-uterine (that's where the baby grows in the mommy's tummy) environment. And we know very very very very little about space.
