Wow, I was just thinking that this gun in orbit would be the cat’s a$$.

I think we need to take it up a notch from “Rods from God” to “Relativistic Kill Vehicle”

From the wiki:

“ExampleA 1 kg mass traveling at 99% of the speed of light would have a kinetic energy of 5.47×1017 joules. In explosive terms, it would be equal to 132 megatons of TNT or approximately 32 megatons more than the theoretical max yield of the tsar bomba, the most powerful nuclear weapon ever detonated. 1 kg of mass-energy is 8.99×1016 joules or about 21.5 megatons of TNT.”
