“The Doomsday Book” by Marshall Brain covers a fascinating weapon from the realm of science fiction: The Relativistic Kill Vehicle (RKV). These are kinetic weapons, like a rifle bullet or a cannon ball, with two differences: 1) they are typically larger, say the size of a phone pole, and 2) they are traveling at something close to the speed of light. This combination gives RKVs enormous energy, similar to that of an asteroid strike. These videos help to illustrate the destructive power of an RKV:
The Breakthrough Starshot Mission
Humanity’s first relativistic vehicle may be a design called Breakthrough Starshot, which will travel at 20% of the speed of light:
