Once you fire a rifle, everything is also Newtonian and deterministic. You still have to move into position, decide which target to fire at, with what ammo etc What you describe is quite close to an actual weapon used in WW2, the SG 500: http://en.wikipedia.org/wiki/Jagdfaust

All of those things have mathematically optimal solutions given known information. It should be trivial to solve the system.

That does not follow. See TSP.

If I could create wormholes at will, I wouldn't traverse the wormhole with the whole ship - just the bombs would suffice.

If you can create wormholes at will, you don't need bombs. Put one end of the wormhole in the target and the other in the center of the sun.

Any guesstimates on how large the wormhole would need to be for it to be a doomsday device? Two estimates, one for a wormhole on the surface of our sun, and the other for its core. I'll try to post my results sometime later.

What about a neutron star? It's probably too exotic to consider how a wormhole would interact with a black hole.

Why waste bombs. If you can create wormholes at arbitrary locations just teleport piece of a star into a planet.

If I could position both ends arbitrarily, a better approach would be to connect the planetary core with a black hole.

There are three fundamental problems I see here: 1) Why put humans on warships at all? Algorithms are probably better at it. Computers would obviously do the heavy lifting anyway (calculating burn times). An algorithm knows no fear, shows no mercy, and does not flee or surrender unless programmed to do so. The only thing left is target selection, and it doesn't seem worth bringing a human along just for that. 2) If y…

I think they main reason the author 'puts' humans in ships is because of when the article was written - 2005. Simply put, drones are a new idea that hadn't really crossed many peoples minds until they started popping up in the military.

Beyond that I think it's a pretty well reasoned piece.

Where is anyone talking about conflicts light-years away? I think we may be discussing different things. The article itself concentrates on intra-system conflicts, primarily because it is trying to deal with realistic space combat using current technology. FTL drives are not part of that paradigm. Yes, obviously if something is light-years away you would need to develop general purpose AI to make those decisions or s…

> The article itself concentrates on intra-system conflicts Neptune is more than 4 light-hours away, and the Oort cloud (discussed as a possible source of projectiles) a full light-year further. So I don't see how anything short of general purpose AI can be tele-operated for intra-system conflicts.

Again, why does it require general purpose AI?

The two examples you cherry-picked are the furthest objects in our solar system. You've literally picked the outlying examples and made them the rule.

The same "problem" could be solved by sending a bunch of what are essentially missiles-carrying-missiles with algorithms that boil down to orders to shoot at any objects that are hot or fast moving or match certain radar signatures. This technology has been in place since the first heat-seeking missile... 1956! There are plenty of other solutions that do not require a general AI (such as sending command ships out).

I postered a comment on the essay, I'll repost it here: You assume the interstellar species will be living on a planet . What if they hollowed out their planet of resources long ago and now live in a cloud of asteroids instead? Asteroids are hollowed out as giant fortresses in space, and a bio dome sphere thingy built inside. As they are living in an asteroid cloud, to prevent impact they would have to attach thruste…

What about a shotgun approach? Take a comet, accelerate it up to a significant fraction of lightspeed (after all, you you have lightyears in which to do so), and trigger a bomb in the comet to blow it apart into a few smaller pieces, each traveling at a significant fraction of c . Rinse and repeat.

That's probably the best suggestion here. Not as easy to deflect something like that.

The point is that the 10-20 seconds latency that was mentioned is not even close to covering the next planet, much less the entire solar system. Yes, you can send off a bunch of heat-seeking missiles, but, as I mentioned in my original post way up this thread, these missiles are routinely defeated by counter-measures even when seconds away from the target. So, in the absence of strong AI, it's vastly more efficient to actually have a few humans on board the ships.

Space combat seems pointless to me. What exactly would they be fighting over? Presumably you want to reach space for resources, so asteroids, planets and moons with minerals, stuff like that. You might also want planets/asteroids/moons that are 'good' for colonization (easily terra formed or already life sustaining). You probably wouldn't see many fights where you are firing at the resource itself. No one with the mo…

You can argue this over in your head a lot, but it's really quite simple in my mind.

If we assume space travel becomes relatively easy (that is to say it is used for more than initial colonization) there will be interstellar commerce. If there is unprotected commerce, there will be pirates. Any time there are pirates, protection will develop. Let us call these peace-keepers the Navy.

If you engage in commerce and you have a powerful Navy, you can influence or even control commerce.

Do you see where I'm going? Most wars are about resources. Commerce is about resources. Anywhere you have commerce, you are liable to develop conflict.

People have been making the argument that war makes no economic sense, and therefore won't happen, since at least 1898:

Sixteen years later, they had the first world war.
