    An atmosphere is not absolutely necessary. Just have a look at the design of an fusion bomb. The nuclear warhead evaporates the styrofoam and you have your shockwave.

    The problem is still that the warhead will vaporize the balls too, and even if it didn't the shockwave produced wouldn't impel the balls outward with enough velocity to make them a universal hazard. On top of that, even if you could set off a shockwave that would drive steel balls outward fast enough to do damage, by the time they got far enough from the blast that the radiation wasn't the main damage effect, they'd be so widely scattered that the odds that they'd hit anything would be remote.

    Still not efficient. Each beam would radiate directly outward from the core, and if a ship was far enough from the core not to be damaged by the radiation from the nuke, the odds that a given beam would hit the ship is very small. At a mile from the bomb (which is how far one would have to be before the x-ray beams would be a bigger threat than the radiation from the reaction itself) the gap between x-ray beams would be more than a hundred yards, so even if you got lucky and hit a ship, you'd hit it with one beam, which is a very inefficient use of that much energy. You'd be better off building an x-ray cannon and using it one shot at a time.

    I have a question about the Nukes in space thing. I know that, without an atmosphere, you don't get the massive shockwave which causes much of the damage that you see in atmospheric detonations. . . but, wouldn't the Nuke still generate several million degrees of thermal energy? Wouldn't it tend to vaporize anything nearby, and melt things that are a little farther away, but still within like a mile or two? Wouldn't it also release a massive amount of Neutron radiation? (I'm not sure - could you effectively shield against that much neutron radiation? I know that space craft have to have a certain level of shielding just to remain safe from 'normal' Solar radiation, but could you effectively shield against the radiation released from an H-Bomb?)

    You're right about how an H-bomb would generate a massive amount of radiation. The problem is that getting a bomb within a mile or two of a ship isn't easy. The most important part is that the bomb can't cover that kind of distance really quickly, in terms of detection. Sure, you can shoot it at your opponent at high rate, but remember that in space you'll probably be considered "engaged with the enemy" from hundreds of miles out. They'll see the nuke coming, and can easily take measures to shoot it as it approaches. All they'd have to do is damage it and it won't detonate. If you could get it close it would certainly damage or destroy a ship, but in space it's the "get it close" part that turns into the challenge.

    I disagree that nukes wouldn't be useful. Put enough tiny metal balls on it, send it into the middle of a fleet of ships and detonate. It will tear everything to shreds.

    No, it wouldn't. Without an atomosphere there's no shockwave to propagate outward, and with no shockwave there's nothing to push the balls. A nuclear detonation isn't like using an explosive that creates an expanding ball of gas. In space it would just be a huge ball of heat and hard radiation, which would melt the balls without motivating them outward at any real rate of speed.
