Laser guns are fine, but I like to invent new futuristic weapons from time to time. So in the most recent edition of Tomorrow News Network, the bad guys (a race of microscopic robots known as the Swarm) use their own gravity as a weapon. Specifically gravitational waves. The attack is so strange and surprising that Earth’s mighty Space Force doesn’t even know what’s happening at first.
Gravitational waves are real things predicted by Einstein’s theory of relativity. Massive objects like planets and stars bend the space around them. We call this gravity. If two massive objects (a pair of black holes, for example) orbit each other rapidly enough, Einstein predicted they’d create waves of gravity, their total gravitational force sometimes doubling and sometimes canceling out. It would be like two fat guys frolicking in a swimming pool: together, they’d make huge waves unlike anything you’d seen in a swimming pool before.
According to the MIT Technology Review, scientists are racing to find evidence of gravitational waves. New research suggests these waves may be stronger than previously thought, meaning current technology may be enough to detect them.
Of course, naturally occurring gravitational waves are nowhere near strong enough to be used as weapons, but I’ve taken some creative license. It’s not hard to imagine that, with the right technology, someone could make artificial gravitational waves. Those waves could do a lot of damage to enemy fleets or planets.
