Interstellar war

[1] The concept provides a common plot device in science fiction, especially in the space opera subgenre.

[5] Writers such as Larry Niven have developed plausible interplanetary conflict based on human colonization of the asteroid belt and outer planets by means of technologies utilising the laws of physics as currently understood.

However, now that the other planets of the Solar System are believed to be devoid of intelligent life, sci-fi writers generally posit some form of faster-than-light drive in order to facilitate interstellar war.

In the 1980's Ace Books published a 3-volume science fiction anthology called The Future at War, edited by Reginald Bretnor.

The first volume, Thor's Hammer, contained stories about wars on Earth and in near-Earth space.
