I especially like such stories as those that deal with space-traveling, because I believe that some time in the near future that is what we will be doing.

The strange, weightless sensation of space-traveling makes it very hard to recognize normally familiar sensations.

Space traveling, via rocket, isn’t a cinch, despite the centuries of study and experiment engineers have devoted to the problem.

Ten days later they landed on Eschaton—a routine landing, but interesting to Kent, who had done little space traveling.

Simply by doing some high-speed space traveling, we will have flung ourselves years into the future.
