[1] The story postulates a transportation device supervised by a dinosaur-like race of aliens that can transmit an exact copy of a person's body to distant planets.
The fictional race, nicknamed "dinos", looks down on humans for being scared of this process, making fun of them for being "weepy".
Reception is later confirmed, and the original, not surprisingly, declines to "balance the equation" by re-entering the scanning and disintegrating device and attempts to escape.
This creates an ethical quandary that is viewed quite differently by the cold-blooded aliens who provided the teleportation technology, and their warm-blooded human associates.
The story concludes with the narrator, a human intern working on the space station housing the device, agreeing with the dinos' philosophy and murdering the woman to balance the equation.
