In all these
shows and
science fiction stories, the
characters are always jumping through wormholes and
einstein-podolsky-rosen bridges and popping up in other
dimensions.
When you read this stuff, they always make it seem like they always start off in our dimension, our world, our timeline. They start off in our world and end up someplace else. When shows like Sliders started off, they made it look like it started here. Quinn's homeworld didnt have flying saucers, or hovercars, (or Gingers for that matter). It was depicted as it was our homeworld.
But with some thought, we realize this is NOT the case. These characters are not people in our world. Why, you say? It's simple:
In our universe, all the characters in these plots are characters in a fictional account, not real life people.
While it is not entirely impossible for visitors from another dimension to be named after characters in a show or book, or have followed the same adventures, it is extremely and highly improbable.
