Frankly were not much closer to near light speed travel, then FTl travel. No
idea how to generae that much power, or hold a ship together at it. Maser
sails could be pushed up that fast, but debres would rip them apart, and no
way to slow them down.
We'ld never bother with trips that would take centuries. Its just rediculas
to send a ship out that long. It couldn't possibly get there before more
advanced ships built later ran ahead of it.

Given the speeds and distences, its pretty hard to do auto intersepts. And
since you have to wind up at the same speeds, you might as well use the same
ship. Can't see a way around that.

But the same techs can't get you faster. Fusion systems, or things like fuel
sail, would require a exponential fuel growth. To get past .3 or .4 you need
a whole concept for tech. Something like zero-point energy, mass/inertia
alterratin - something wild.
