Right. That's what I was trying to say in my Last post. I am in no way trying to say we will colonize the galaxy in 4,000, 15,000 or even a million years. I was just trying to put into numbers that even at sublight speeds it should be possible in an extremely short amount of time as compared to the life of the galaxy. The fact that despite this teh galaxy is not colonized doesn't prove anything, but it certainly gives weight to the probability that there are huge factors making interstellar travel hard. Factors beyond just needing some faster propulsion system.
