Time Traveling to Jesus
Science fiction stories have long been filled with marvelous gadgets, some of which have appeared in earlier chapters. Just to mention a few, even if I repeat myself, they include automatic language translators, invisibility cloaks, faster-than-light space ships slipping in and out of something called hyperspace, supercomputer brains, matter transmitters (‘beam me up, Scotty’), disintegrator ray guns, and tractor beams (think of a ray that pulls stuff towards you). But the ultimate SF gadget has to be the time machine. The other gadgets do neat things, sure, but that’s pretty much the extent of them. Time machines, while a gadget that opens the future to us, also appeals to our nostalgia for the past.
