[QUOTE="Umbran, post: 5838771, member: 177"] We are not yet at the Star Wars and Star Trek level, where space engines have nigh-unlimited fuel, and you can drive around willy-nilly. Every ounce of propellant on your ship has to be lifted from the ground into orbit - it is heavy and expensive, and so limited. [color=darkorange]First off, please leave the religious commentary out next time, thank you.[/color] Second of all, yes, heat. The Sun warms us through electromagnetic radiation. So yes, you can use radiative cooling in space. But, compared to the convective and conductive cooling options available on the ground, radiative cooling is typically very slow, and/or requires huge radiating fins Huge fins radiating heat means "huge target that is super-easy to detect in space". Not exactly what you want from a weapons platform. [/QUOTE]
