Campbell Memorial Award for Best Science Fiction Novel. The novel was widely hailed by both critics of science fiction and mainstream literature for its fusion of detailed character development and interpersonal drama with more standard science fiction fare such as time travel and ecological issues.Fact|date=February 2007 Pocket Books used the title of this book for their science fiction imprint.

Plot summary

The story is written from two viewpoints, equidistant from the novel's publication in 1980. The first thread is set in a 1998 ravaged by ecological disasters such as algal blooms and diebacks on the brink of large scale extinctions. Various other events are mentioned in passing, such as student riots and an event of nuclear terrorism against New York City which took place before the events of the novel. This thread follows a group of scientists in the United Kingdom connected with the University of Cambridge and their attempts to warn the past of the impending disaster by sending tachyon-induced messages to the astronomical position the Earth occupied in 1962-1963. Given the faster-than-light nature of the tachyon, these messages will effectively reach the past. These efforts are led by John Renfrew, an Englishman, and Gregory Markham, an American most likely modelled on Benford himself. Overseeing their efforts is Ian Peterson, a womanizing member of the World Council.

The second thread is set in the University of California, La Jolla, in La Jolla, California, in 1962 where a young scientist, Gordon Bernstein, discovers anomalous noise in a physics experiment relating to spontaneous resonance and indium antimonide. He and his student assistant, Albert Cooper (also likely based on the author and his experiences at UCLJ), discover that the noise is coming in bursts timed to form Morse Code.

The resulting message is made of staccato sentence fragments and jumbled letters, due to the 1998 team's efforts to avoid a grandfather paradox. Their aim is to give the past researchers enough information to start efforts on solving the pending ecological crisis, but not enough that the crisis will be entirely solved (thus making a signal to the past unnecessary and creating a paradox).

Due to the biological nature of the message, Professor Bernstein shares the message with a professor of biology, Michael Ramsey. Since the message also gives astronomical coordinates, he also shares it with Saul Shriffer, a fictional scientist who is said to have worked with Frank Drake on Project Ozma. Initially, these characters fail to understand the true meaning of the message. Ramsey believes it to be an intercepted military dispatch hinting at Soviet bioterrorism, while Shriffer thinks the message is of extraterrestrial origin. Shriffer goes public with this theory, mentioning Bernstein in his findings. However, Bernstein's overseer, Isaac Lakin, is skeptical of the messages and wants Bernstein to keep working on his original project and ignore the signal. As a result of this interruption in their experimentation, Bernstein is denied a promotion and Cooper fails a candidacy examination. The signal also exacerbates difficulties in Bernstein's relationship with his girlfriend, Penny.

In 1998, Peterson recovers a safe deposit box in La Jolla containing a piece of paper indicating that the messages were received. Meanwhile, it is clear that the viral nature of the algal bloom is spreading it faster and through more mediums than originally expected. Strange yellow clouds that have been appearing are said to be a result of the viral material being absorbed through the water cycle, and it soon affects the planet's agriculture as well, resulting in widespread cases of food poisoning. Flying to the United States, Markham is killed in a plane crash when the pilots fly too close to one of the clouds and experience seizures.

In the past storyline, now advanced into 1963, Bernstein refuses to give up on the signals. He is rewarded when the signal noise is also observed in a laboratory at Columbia University. Using hints in the message, Ramsey replicates the conditions of the bloom in a controlled experiment and realizes the danger it represents. Bernstein finds out that the astronomical coordinates given in the message represent where the Earth will be in 1998 due to the solar apex. He also receives a more coherent, despairing message from the future. Having built a solid case, Bernstein goes public and publishes his results.

This decision has monumental consequences. On November 22, a high school student in Dallas is sent by his physics teacher to the Texas School Book Depository to get a copy of Bernstein's findings. There he interrupts Lee Harvey Oswald's assassination attempt on President John F. Kennedy, attacking the shooter and sending the would-be fatal third shot awry. Though seriously injured, Kennedy survives. This paradox creates an alternate universe and forever ends the contact with the original 1998.

The concluding chapters portray the 1998 of the original timeline as a bleak, failing world, the intensified ecological disaster taking a noticeable toll on the human way of life. Peterson retreats to a fortified country farmhouse which he has obviously prepared well in advance. Renfrew continues to send out signals (including the more coherent one that Gordon receives) until the building's generator gives out. Before it does, however, he receives a signal purportedly from the year 2349.

In the final chapter, set in the alternate 1974, an awards ceremony is held for achievement in science. In light of Kennedy's survival, the United States President giving out the awards is William Scranton, who is said to have defeated Bobby Kennedy due to a telephone tapping scandal. The scientists whose work stemmed from the signal are honored, including Bernstein, who receives the Enrico Fermi Prize for his discovery of the tachyon.
