==Plot== In the year 2055, time travel is a practical reality, and the company Time Safari Inc. offers wealthy adventurers the chance to travel back in time to hunt extinct animals such as dinosaurs. A hunter named Eckels pays the company to travel to the Mesozoic to hunt a ''Tyrannosaurus rex''. He expresses relief that the candidate Keith won the presidential election the day before, noting that he might want to use a time machine to escape if the would-be dictator Deutscher had become President of the United States instead. The company emphasizes strict rules to avoid altering the future, such as staying on a levitating path and only shooting marked animals destined to die naturally. Eckels, joined by other hunters and guided by Travis and Lesperance, is warned about the catastrophic consequences of even minor disruptions to the past, like killing a single mouse, which could cascade through time and alter history.
During the hunt, Eckels panics upon seeing the massive ''Tyrannosaurus'' and returns to the time machine. The group kills the dinosaur, but Travis is enraged to discover that Eckels stepped off the path into the dirt. He orders Eckels to retrieve the bullets from the corpse to prevent further disruption, then threatens him as they return to 2055. Upon arrival subtle changes in the air, colors, and a sign's spelling indicate that the timeline has shifted. Eckels finds a dead butterfly on his boot and realizes that his misstep altered history. Most shockingly, he learns that the "iron man" dictator Deutscher has won the presidential election instead of Keith. As he pleads on his knees that there must be a solution, Travis raises his rifle and there is "a sound of thunder" (implied to be a gunshot).

==Influence== "A Sound of Thunder" is often credited as the origin of the term "butterfly effect", a concept of chaos theory in which the flapping of a butterfly's wings in one part of the world could create a hurricane on the opposite side of the globe. The term was actually introduced by meteorologist Edward Norton Lorenz in the 1960s. However, Bradbury's concept of how the death of a butterfly in the past could have drastic changes in the future is a representation of the butterfly effect and is used as an example of how to consider chaos theory and the physics of time travel.<ref>{{Cite web | url = http://www.philly.com/philly/blogs/evolution/Time-and-The-Physics-of-Ray-Bradbury--.html | title = The Physics of Ray Bradbury's 'A Sound of Thunder' | work = The Philadelphia Inquirer | date = June 15, 2012 | access-date = September 2, 2015 | first= Faye | last = Flam}}</ref>
