In Star Trek, time travel is very common. But, I am interested only in travel to past Earth and that’s also when it hosted humans (Q transporting Picard to Earth when life was originating won’t be counted). Some examples in my mind: In Star Trek: The First Contact, Borg queen and Picard went bac...

When the elves said they were leaving middle earth where were they going? For some reason I thought they were going underground. If it was another continent couldn't sauran just build ships?

Why doesn't Sam kill Ruby when he had the chance? I mean she lied to him, she's a demon. Sam and Dean hunt demons why?

A humorous short story from an anthology read 1970-80s. Humans have established a space station that orbits both stars of a twin system. As a result days and nights are of radically different lengths. The worse problem is during the journey from one star's proximity to the other they pass through...

I read this book a over a decade ago. and even then the book looked old. I can't say exactly when it came out. Each chapter was written in a different style. Some in first-person, some in third-person, some in debrief report style. I recall the book cover being completely blank, with no title. Th...

Looking for a graphic novel(s), roughly mystery stories targeted at high primary/ low secondary readers.
