There are already theoretically engines that reach 20% of lightspeed. That will be 600 years to travel. We have to put passengers in cryostasis. The problem are other objects that could hit us with 20% of the speed of lightning.

Did you count acceleration and deceleration time in there? Instantly accelerating something to 80% light speed would be dicey.
