Time Safari Inc. is a safari that takes people in the present to the faraway past, in the short story "A Sound of Thunder".
<u>Explanation:</u>
"A Sound of Thunder" is a science fiction short story by Ray Bradbury.
In it he presents the further-est future, wherein it is possible to travel back in time to the age of the dinosaurs.
It invites wealthy hunters to enjoy the hunting of the dinosaurs, an experience that would otherwise not be possible.
But there are certain precautions that the time safari guides have to take which are:
- people who are traveling to the past should not step out of the time path that they are traveling in, as as to maintain the time path.
- the safari guides tag the dinosaurs which can be hunted upon, and only those creatures can be shot at by the travelers. This is done by the guides traveling beforehand and knowing which creature is about to die, and targeting that creature only. This way the past does not change at all and is maintained.
- no one is supposed to take along anything from the past environment except for the memories and the experience, so the past is kept as it is supposed to be, or else the future would change.
Thus, these are the guidelines that the safari guides take in the "A Sound of thunder".
