QUESTION: wow thank you so much and your response time was incredibly fast i havent even heard from another site i emailed a week ago
         1.Just how different can one universe be
         2. if we had the right technology could we travel to          a parallel universe
         3. could we contact a parallel universe with todays current technology
         4. How was the idea concieved

         sorry about the odd formatting.
         


         sincerely,
         john

Answer
How different = infinite.
Right technology = unkown, we have no experimental evidence for or physical knowledge of how such universes work.
Again, we've never observed direct evidence of parallel universes.  How could current technology "contact" them?
The idea is a convenient mental device for conceiving quantum mechanics. I'm not sure of its exact origins, but probably quantum uncertainty had something to do with it.

Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
