PhD Candidate Talks About the Physics of Space Battles

darthvader100 writes "Gizmodo has run an article with some predictions on what future space battles will be like. The author brings up several theories on propulsion (and orbits), weapons (explosives, kinetic and laser), and design. Sounds like the ideal shape for spaceships will be spherical, like the one in the Hitchhiker's Guide movie."

The problem is that reducing the profile in one direction means you have to make it larger in a different dimension. Now, that's not much of a problem when you're fighting 2D land-battles, but zero-gravity gives you the ultimate 3D battle-space. If your enemy is smart enough to put one fleet directly in front of you while having another flank from the top or bottom, all you've done is make your ships easier to hit.

If you're looking at it purely from the perspective of presenting the smallest profile possible, your best bet would be a needle-shape. Very long, and as thin as possible. However, that runs into other problems, such as maneuverability.
