There is definitely discussion going on about the type of relationship you mentioned and others types as well.
Example A Russian Oscar submarine is a cylinder meters long and has a beam of 18 meters, which would be a good ballpark estimate of the size of an interplanetary warship. If it was nose on to you the surface area would be square meters.
If it was broadside the surface area would be approximately If the Oscar's crew was shivering at the freezing point, the maximum detection range of the frigid submarine would be If the crew had a more comfortable room temperature, the Oscar could be seen from even farther away.
To keep the lifesystem in the spacecraft at levels where the crew can live, you probably want it above K where water freezesand preferably at K room temperature.
Well I'll just beam my heat the other way! Glancing at the above equation it is evident that the lower the spacecraft's temperature, the harder it is to detect.
To actively refrigerate, you need power. So you have to fire up the nuclear reactor. Suddenly you have a hot spot on your ship that is about K, minimum, so you now have even more waste heat to dump. This means a larger radiator surface to dump all the heat, which means more mass.
It will be either a whopping two to three times the mass of your reactor or it will be so flimsy it will snap the moment you engage the thrusters. It is a bigger target, and now you have to start worrying about a hostile ship noticing that you occluded a star.
John Schilling had some more bad news for would be stealthers trying to radiate the heat from the side facing away from the enemy. Besides, redirecting the emissions merely relocates the problem.
The energy's got to go somewhere, and for a fairly modest investment in picket ships or sensor drones, the enemy can pretty much block you from safely radiating to any significant portion of the sky. And if you try to focus the emissions into some very narrow cone you know to be safe, you run into the problem that the radiator area for a given power is inversely proportional to the fraction of the sky illuminated.
With proportionate increase in both the heat leakage through the back surfaces, and the signature to active or semi-active reflected sunlight sensors. Plus, there's the problem of how you know what a safe direction to radiate is in the first place.
You seem to be simultaneously arguing for stealthy spaceships and complete knowledge of the position of enemy sensor platforms. If stealth works, you can't expect to know where the enemy has all of his sensors, so you can't know what is a safe direction to radiate.
Which means you can't expect to achieve practical stealth using that mechanism in the first place. Sixty degrees has been suggested here as a reasonably "narrow" cone to hide one's emissions in. As a sixty-degree cone is roughly one-tenth of a full sphere, a couple dozen pickets or drones are enough to cover the full sky so that there is no safe direction to radiate even if you know where they all are.
The possiblility of hidden sensor platforms, and especially hidden, moving sensor platforms, is just icing on the cake. Note, in particular, that a moving sensor platform doesn't have to be within your emission cone at any specific time to detect you, it just has to pass through that cone at some time during the course of the pre-battle maneuvering.
Which rather substantially increases the probability of detection even for very narrow emission cones. Somebody suggested using a continuous blinding barrage of nearby nuclear detonations in order to hide thrusting.
The timescale of the radiant emission from a nuclear detonation in vacuum is measured in milliseconds. The recovery time of a good CCD array is measured in microseconds. You'll need to detonate nuclear explosives at a hundred hertz, minimum, to cover an accelerating ship.
That's going to get expensive. It also rather clearly indicates where the enemy should start looking John Schilling The problem with directional radiation is that you have to know both where the enemy sensor platforms are, and you have to have a way of slowing down to match orbits that isn't the equivalent of swinging end for end and lighting up the torch.
Furthermore, directing your waste heat and making some part of your ship colder, a related phenomena requires more power for the heat pump - and every W of power generated generates 4 W of waste heat. It gets into the Red Queen's Race very quickly.
Imagine your radiators as being sheets of paper sticking edge out from the hull of your ship. You radiate from the flat sides.
If you know exactly where the enemy sensors are, you can try and put your radiators edge on to them, and will "hide". You want your radiators to be degrees apart so they're not radiating into each other.
Most configurations that radiate only to a part of the sky will be vastly inefficient because they radiate into each other. Which means they get larger and more massive, which reduces engine performance The next logical step is to make a sunshade that blocks your radiation from the sensor."Ain't No Sunshine" is a song by Bill Withers from his album Just As I Am, produced by Booker T.
Jones. The record featured musicians Donald "Duck" Dunn on bass guitar, Al Jackson, Jr. on drums and Stephen Stills on guitar. String arrangements were done by Booker T. Jones, and recorded in Memphis by engineer Terry schwenkreis.com song is in the key of A minor.
Perhaps the most surprising thing about AMERICAN VI: AIN'T NO GRAVE isn't that it was released (we love to exploit our deceased talents), but that it is such a solid album.
First off, as Ken Burnside explains, there is one major way that detection in space is different from detection on Terra's surface: There Is No Horizon. Since Terra is a sphere, the curvature means if you are of average height, the fact your eyes are about meters off the ground means anything much further away than kilometers will be invisible.
Background. The song's beat is produced by Big Jaz who samples "Seven Minutes of Funk" by the funk band The Whole Darn Family. The song's chorus interpolates "Ain't No Woman (Like the One I've Got)" by The Four schwenkreis.com "Ain't No Nigga" single goes under the clean alias "Ain't No Playa".The music video of the song, which was shot in Miami, starts with a scene similar to a scene of the film.
