"At the current rate of progress it will take another 2000 years to figure out the rest."

Even if the gamma ray jets point in our direction, the solar system will likely be protected by a Dyson shell (or similar giant structure) by then. Less developed colonies in other star systems might not be so fortunate, however. 3 "Our Sun may exit the Local Cloud, also called the Local Fluff, during the next 10,000 years."

These "resettlers" are elderly people who lived in the region prior to the disaster. Today there are approximately 10,000 people between the ages of 60 and 90 living within the Zone around Chernobyl. Younger families are allowed to visit, but only for brief periods of time. "Eventually the land could be utilized for some sort of industrial purpose that would involve concrete sites. But estimates range from 60–200 years before this would be allowed. Farming or any other type of agricultural industry would be dangerous and completely inappropriate for at least 200 years. It will be at least two centuries before there is any chance the situation can change within the 1.5-mile Exclusion Zone. As for the #4 reactor where the meltdown occurred, we estimate it will be 20,000 years before the real estate is fully safe."

All of this dumb matter and energy around us will wake up and become sublimely intelligent. Then it will spread out to the whole universe at the fastest speed information can flow. And one could make an argument that it’s not going to take an infinitely long time because there may be other ways to get to other parts of the universe through shortcuts like wormholes, which physics has postulated. Eventually the whole universe will, essentially, wake up."
