Since we are really talking Science Fiction, Asimov's "End of Eternity" gets my vote for the best time travel book. And then there is Hogan's "Thrice Upon a Time". If you haven't read those two, I highly recommend them.

Personally I think teleportation would be much more practical.

“Personally I think teleportation would be much more practical.”

Absolutely. Teleportation would involve creating a bit map at the atomic level of the item/person to be teleported. Once you had the bit map, you could recreate that item/person anywhere you want after you destroy the original.

The current limitations on technology that need to be solved do not appear to be impossible given current theory.

It will take advances in computer speed, memory, power generation, ability to scan at the atomic level, and practical chemistry in combining basic elements to produce anything.

Nanobots? Imagine giving the blue print (bit map) to a bunch of nanobots who have access to quanities of all the elements. Then they build whatever you want.

Thanks, for the book recommendations. I do like science fiction.
