So would modern science include 1, 2, and 4 from Bryan's list in post 15?
If you want to give your mind some direct interaction with regard to the consideration of what is possible and what is impossible, try watching a "sci-fi/fantasy" movie.
In fact, just last night I watched a sci-fi movie that had all sorts of impossible things happening.
Now in our current world we have technology built upon science. But science is a complicated thing in itself. And science uses concepts, models, and theories.
QuoteDisplay MoreConcept
I have this concept of a unicorn in my thoughts. I know unicorns do not exist but I have this idea of what they would look like if they existed
Model
I had this model made to make it easy to explain my concept. You can see from my model my concept idea looks like a horse with a horn growing from the forehead
Theory
I have a theory that unicorns might exist on other planets and that is where our concept of unicorns comes from. I intend to test my multiple ideas into the theory of unicorns on our planets by checking people who think about unicorns and what planets they also think of. Perhaps I can narrow it down to 1 planet
Concept - Generally (there can be exceptions) a idea about something which does not exist or a idea about something which might exist if we build it
Model - Build a model or make a drawing to show what the concept will look like if made
Theory - A collection of ideas which can be arranged or linked together to produce a new idea which can be tested to see if agrees with reality
