“When it came to time travel, science and science fiction and fantasy had flip-flopped. Nobody was going to create a machine that traveled to the future or the past. Time machines might be accepted in science fiction as an enabling device to get the story moving, but they're like faster-than-light space ships-- neither one is going to happen any time soon, not with any technology we know how to implement.The guys who had it figured were the fantasists, Dennis. The Finneys and the Mathesons and the Ellisons and the Serlings. No machines and no advanced physics, at least not most of the time. Just an overpowering desire. Just need and longing and pain and regret and the right talisman or the right surroundings. Put the right person in the right place, and perhaps with the right objects, and the potential for time travel is there.”
