there is absolutely no hiding in space unless you've got a moon or planet between you and your adversary

anything over ~300 kelvin will be visible for several months within 100 AU if we stop improving telescopes today

any spaceship big enough to deploy useful weapons warmer than 250 kelvin (the lower bound for a crewed spacecraft) will be visible within 50 AU

anything burining so it can reach its target (a missile) will be visible to laser defense with ample time to spare


it's possible that an unmanned weapon could drift slowly toward a target, never accelerating after launch, and maaaybe avoid radar and optical observation, so maybe you could bombard small outposts over the course of several years. this will never work against enemy spacecraft

accelerating loads of asteroids at a planet from far away like in starship troopers is the best cause even if theres advance warning its still gonna be a pain in the rear end to round them all up

they did this w/ stargate but it was another universe instead of a black hole and like hosed up poo poo that totally boned the other universe instead of heat.

and then later in stargate dave nelson from newsradio stole the tech and tried to use it to solve global warming but it hosed up and was gonna destroy the planet, but then bill nye saved the day.

the larger the radiator, the farther away it can be seen even if its average temperature is relatively lower

of course in my earlier numbers i'm assuming modern infrared astronomy is the peak of our advancement and we never have more than one ir telscope and no radar astronomy because i guess radars are illegal in the future thanks cyber obama

presumably by the time we're spending a trillion dollars a pop on laser battleships we'll pop 20 or 30 telscopes up in the sky for a daily refresh of objects that might try to kamikaze our space investments

not a bad idea if you think the war will last longer than it takes for the asteroids to reach the target or you keep real good records so you can help stop them after a truce is signed

maybe hollow out the cores of your weaons and fill them with a stable explosive that you can signal for self destruct when the war is over

personally i think the last big collapse will happen sometime c.2045 and then that's about all she wrote for progressive technological society

but if we somehow make it through collapse of the global food supply and the subsequent failures of the mega cities and go on to build interplanetary warships they'll obey the laws of physics so they'll be prohibitively expensive and cramped and uncomfortable but also have lots of cool lasers and particle beam weapons

If you want something done, do it yourself!
there are two ways to win at space wars:

1. be peaceful, and rely on the assumption that everyone else will be peaceful always and forever

2. annihilate enemy civilizations before they get good enough at doing things in space to be a threat


what i'm saying is maybe there's a reason earth gets an extinction level asteroid strike with such regularity

and maybe there's a really good reason that we've been really stubbornly dragging our heels re: any propulsion technology more advanced than puttering around with little dinky chemical rockets :tinfoil:

this is similar to the plot of asimovs the gods themselves where earth and a parallel universe exchange isotopes that are impossible in the other universe due to differences in physical laws and use the nuclear decay as an energy source.

USSMICHELLEBACHMAN posted:

sure

call it Senator Propulsion by Magnetic Field Induction

you're looking at a bucket load propellant coilgun so you'd get 100 pulses of thrust, each pulse would be around 1100kN

unfortunately each pulse would be fatal to the payload as each senator would be exposed to 1200G acceleration force. however, each senator would make an effective kinetic weapon, so you would have that going for you. also since the payload won't survive the launch you can make the gun relatively short (~1200m) and there's no real need to keep the engine pressurized and you can power it with a nearly unshielded fission power plant.

the weight of the coils and coolant track would preclude a high TWR, you're probaly in the neighborhood of 260 tons dry mass and 10 tons of senators. each pulse would give you a momentary acceleration ~0.4G, so you'd probably need to ferry up the rest of the congress and most of their aides if you plan on getting anywhere

it's an anthology series so they'll have new characters somewhere else. not sure if it will have the same cast

they ended the series really well, i liked that they left it ambiguous whether there was actual ~2spoopy~ poo poo going on or wether it was just ur typical, mundane crazy hick pedo-murder-rape cult

this is an engineering problem that could in principle be solved and would work to shield a non-accelerating spacecraft from ir detection by a point observer

the problem is you would need a real big real no joke heat shield that would need a lot of coolant and a lot of tailing radiators, something like a 60 km wide plate with 20 km of radiators dangling out the back

as long as you're enemy only has a single observatory you can get pretty close, but if they use radar you'd need a stealth geometry and a material that retains radar absorbtive properties at super low temperatures.

even if such a material even exists they could still just look at the sky with a regular telescope and watch for glint from the heat shield. okay, you paint it black (more work for your radiators) so they watch for unexpected star occlusions and pretty soon have a good enough idea of your cross section and speed that they are probably getting pretty steamed about your evident sneak attack
