? Are you serious. We have concepts for light driven probes now. They even can slow down, by ejecting a parabolic lightsail, that bounces light from the opposit direction back to them. Its all lightweight and - way more feasable, if you abandon the " a human has to go there idea". Communication would be an issue, but otherwise...

Yeah I'm familiar with the old "Devil's pogo stick." Apparently thermonuclear Orion could achieve as high as 10% the speed of light, which would get you to the Centauri system within a single human life span (barely).
