3 Days, 9 Months, 27 Years (The Time Traveler's Passport)

by John Scalzi

The client, however, has aged three days, or nine months, or twenty-seven years. They have been through a time machine, after all. This is how the time machine works.

The theoretical process is almost never what actually happens. Theory is almost never practice.

It is psychologically important, when traveling through time, to have another human be the last and first thing you see.

The thing that made time travel useless for historians is what made it profitable for tourism: Introducing information from one reality to another alters the second reality irrevocably.

The butterfly effect is correct, but the butterfly is in another reality entirely.

“History” stops being accurate the moment you observe it.

Every step changes everything, always.

Temporal tourism, as it happens, is not cheap.

Variety is the essence of tourism.

It is pleasant to work with, and for, pleasant people.

whatever reality I am in, in the end, I carry only myself into it. Realities change, and I am the constant.
