I don't recall the name of the short story, but in one of the many paperback collections of Trek short fiction was a story in which the original cast actors step into the transporter set and upon issuing the "energize"…

Seems to me we need to think about solutions that negate these delays regardless of distance. Since research into quantum computing is afoot, how about quantum routers that use a collection of entangled particles to instantaneously send data across interplanetary or even interstellar distances? These could be major…

All these discussions about the Grandfather Paradox fail to take something into account that could easily eliminate the paradox entirely. If the Many Worlds Theory of quantum mechanics holds true, then there are an infinite number of alternate realities and what to our linear thinking appears to be time travel within…
