Um.... 186,000 = c in miles per second, approx, (I don't happen to know its speed in KM) 0.05 = fishy's multiplier, makes 0.5C be... 9,300 = miles per second 33,480,000 = miles per hour 53,880,837 = kilometers per hour (I think)
58,000 = kilometers per hour = the fastest man-made object ever to leave Earth's orbit.
"You keep using that word. I don't think it means what you think it means."
Honestly, I think the thing that keeps technology from spreading across the universe is the frail nature of life and the transitory nature of knowledge. Even if you could travel at relativistic speeds, it means the life has to survive for decades in a tiny tin can to get anywhere. In order to thrive for that length of time, life needs planet-sized ecosystems.
Strap a big enough engine to a small planet, sure, we could colonize the universe...
