alt Hacker NewsIf humanity doesn't perish in the next hundred year and masters interplanetary spaceflight, antimatter drive is the logical next step in propulsion after fusion.
Interstellar spaceflight will become (barely) feasible once spaceships can reach velocity between 0.02 to 0.1c are possible. Even assuming non-100% conversion efficiency, antimatter has enough energy density to provide this capability.

Interstellar flight is a new physics problem, not a smash-the-tiny-rocks-together-to-make-bigger-bang problem.
We're not going anywhere without a revolution in our understanding of the universe.

Maybe. Beamed propulsion makes a hell of a lot more sense in the solar system.
