Personally, it does not faze me what the scientific explanation is or if one exists at all. Freespace2 is a game, and beams had a very specific design in that game. The ball would amass at the turret point to a noticeable size, and a relatively smaller, more focused beam, would shoot out from the turret tip. The previous mediavps didn't really do much to change that design except make textures more detailed and make the weapon's overall effect larger. Mediavps3612, however, changed the design of the weapon by shrinking the warm-up bulb to the point where it's practically negligible, pretty much in my mind erasing one of the characteristic features of beam weapons. This to me is a design change, and I am not convinced by the arguments that have been presented in favor of that change. It comes off as unnecessarily moddish and unfreespace like.
