Plot summary

The point-of-view character, a physicist with a time-travel theory, is approached by retired Senator William Proxmire. Proxmire has come up with a scheme to abolish such money-wasters (as Proxmire views them) as space travel. His plan is simple; many of those who worked for or advocated space travel cited the science fiction of Robert A. Heinlein as their inspiration. However, the iconic writer only began his career after being discharged from the United States Navy due to tuberculosis. If a time traveler were to cure Heinlein, he would presumably remain in the military and this impact on history would be negated.

Sure enough, the scheme is carried out. However, Proxmire finds out that he has not succeeded as well as he would have liked. Although Heinlein's absence from the literary world of the new timeline did neutralize the science fiction magazines of the 1950s, other authors took Heinlein's place just a decade later – in mainstream literary magazines such as The New Yorker. Science fiction thus gained an air of respectability, and inspired people to even greater achievements. Proxmire's political career ended when this culture of science fiction fans boycotted Wisconsin cheese in response to his Golden Fleece Awards.

The new timeline is far more technologically advanced; solar power satellites can be seen in the night sky, a lunar colony exists, and a mission to Mars is underway. The healthy Heinlein turned out to be as skilled an officer as he would have been an author, and is now an admiral with great influence over an equally healthy space program – he denies the Russians spacecraft, but has placed a number of cosmonauts on the Mars mission as payment for fusion bombs to be used in the ship's ORION drive.
