Also in space there is no real above or below.
any direction would pretty much be the same no matter which way you are facing. also cordnating a fleet of ships shouldnt be to hard if they have been around long enough. The navy sure can command their fleets well, and thats because years of perfection. Space stratergies should exist after means of space combat are achieved. |

Not to mention advances in computing will make coordination in that regard much easier. But truly realistic space combat will probably look nothing like anything we've seen in entertainment.
It would take place at far beyond visual range, involve missiles and point defense, and maybe a laser or two. And be pretty slow, with exchanges taking minutes or maybe even hours.

You do know what zero gravity means, right? No gravity? No force pulling stuff down or any other direction, hence allowing you to shoot really far without angling in any way to try to compensate? And you know that cold vacuum is VACUUM for a reason right? No air? No air resistance or friction? All of which allow anything in space to travel farther and faster than in air? Close? Do you have any idea how fast a space shuttle orbits the Earth? Last I recall it was 90 minutes per complete orbit, and that is HELLA faster than your car or mine. Wanna try fighting in space at those speeds? Pfft! You'll be passing by each other faster than your eye could catch. Maybe with a computer you can hit stuff, but most likely space combat will involve ships sitting or strafing at thousands of kilometers apart from each other, lobbing missiles and lasers at each other. There's a better chance at dodging incoming fire or out-ranging each other. The most common munition will likely be nuclear weapons, and fighting at point-blank range with these is stupid. Quote:
You only start to lose light at huge distances like light-days or light-years, and I hardly doubt, without some extreme tech, that space battles in the foreseeable future will take place at those kinds of distances. There is so much wrong with what you just posted that..... just go brush up some physics, okay?

Comets have been doing so for ages, why wouldn't shells be able to go long distances, even when out of fuel they would keep going but I do agree that the effective range of weapons can only go so far: "....Incoming missle, ETA: 4 days, 6 hours and 12 minutes..." "Game over Man! We're done for!"

Gravity is just another force. In terms of the planet earth, it's a force that's pulling (although every force is really a push, never a pull, but for the sake of simplicity...) everyone to the ground. If you tossed a ball upwards, it would come back down. In space though, the force of gravity is so negligible that if you toss a ball one way, it's bound to keep going for who knows how long until something stops it. That's why combat range in space will be very very large. It doesn't take much force to accelerate something in an environment where there is very little other force acting on whatever you're trying to propel at however-insane-velocities-you-want. And since any object in deep space is likely to keep going that way, you don't need any more force to keep that projectile going as well.

Now, what is light? Light is basically a photon or collection of photons. These are sub-atomic particles. They are NOT molecules. So how exactly could you cool down or heat up light? Light can heat up stuff though since those photons bounce into the molecules of an object and get them moving, hence heat them up. Therefore, all the heat you may feel in space is either through light, or through radiation. Or if you're touching a warm part of a ship's hull. Or another person. Whatever. As for rockets, yes they get cool, but not cool enough to freeze them or anything.

Anyway, yes, there has to be something else for there to be something new. I never once said that the laser came from nowhere. Obviously it needs a source of energy. Surrounding heat however has no real effect on it. And for the second part, I never said anything about the sun. You're trying to make me out to be saying something that I didn't. And both sunlight and lasers heat up stuff, simple as that. One does it better than the other, but overall the main point still rings true.

(sorry i take long time to reply, my homeboy just chirped me) and as you know the laser is heat. it heats stuff up because its traveling heat. i cant imagine how far a high power laser can travel with no temperature ^^;;. |

As for infrared, just as an aside, that's also not heat itself but simply a wavelength of light that is emmitted in the presence of hot objects. Infrared is not heat itself. Since it's present near hot objects we typically assume it's a sort of "heat sensor" but we're not actually sensing the heat, instead we're sensing a specific type of light that is given off by a hot object.

You could possibly make a warship that could survive near-miss nuke blasts, but your ships are going to have hull thickness in the tens of meters. Think a solid tube of titanium. Even then, most of the exterior systems are going to be destroyed. Once you start slinging nukes about, space combat becomes a zero sum game. Once you are detected, you launch your long range nukes - expect that weapon travel times could take days, and that your target is going to launch nuclear countermeasures to destroy your nukes in transit. Space combat could start to look a lot like submarine combat. Lots of stealthy designs, doppler radar to determine relative speed and heading (so you know where to launch your missiles to intercept), towed array (your active sensors dragged 30/50km behind you) and advance intelligence (UAVs etc.). Quote:
An ideal laser weapon would not 'cut' a hull but dump as much of its energy in as concentrated a spot as possible in as short a time as possible. Instantaneously boiling off a section of the hull and causing a surface explosion that would cause more damage. 'heat' is a property of matter. In order to transport heat from one ship to another you would fire a plasma (very hot gas). THough a favoured staple of science-fiction, plasma isn't that effective as a weapon really. Slow, by comparison with light, which limits its range, its charged, so its trajectory will be affected by magnetic fields (thats its countermeasure right there) and the one thing a hot gas won't want to do is stay in a nice coherent beam. |
