I always see scientists trying to create the ultimate weapon. And more often than not, it turns on them. The parallels hearkens back to Frankenstein, I know that.

Do you believe if 1 person were to go back into time and meet his other self it would change the course of history? How and Why? What else could possibly happen with time travel to the past and future?

Do you believe that a parallel universe exists and that we have a twin in the parallel universe that does the exact opposite as we do in this universe? What do you believe about parallel universes?

When do you think scientists will discover time travel and parallel universes?

I am trying to remember the name of a story I read as a child (1980?). It may have been juvenile science fiction and may have been a short story. It involved a group of researchers who had discovered an alternate dimension into which they could send objects, which would then be transformed. A cloth with an overhand knot in it might turn into a bicycle, while a copper cable with three nuts would turn into a hamburger bun (or whatever). The only thing that didn’t transform was horses, which might grow bigger or smaller, or grow wings, but would pretty much stay the same. The scientists were using the alternate dimension as a kind of manufacturing tool, trying to find the combination of objects that when put through the portal would come back as a ray gun, for example. The main character (a child?) is forced to enter the portal himself, and the story involves what happens to him on the other side.

Do you know it, or can you suggest another possible source for an answer?

I am interested to know where and how imagination and creativity takes its place in the scientific process. We often hear about how reason and rationity are important back- bones to the scientific process but I’m wondering how much of what is something usually attributed to art is also very important to the sciences. I’m interested in any views from scientists in any area.
